How Do Raised Toilet Seats Work ?


Until you spend time someone with mobility issues you probably won’t ever come into contact with a raised toilet seat, or for that matter have any idea what they do. It’s as my parents caregiver that I first started to learn about them. There are a number of types, and they work in very different ways, and to my mind with varying degrees of success.

How do raised toilet seats work ? A raised toilet seat is a device which is either fitted onto, or above, the seat or bowl, of a toilet. The raised toilet seat makes it easier for a person to sit down onto the seat, or stand back up, from it, by reducing the distance.

Raised toilet seats are meant as a toilet aid for anybody with –


  • mobility issues
  • joint problems
  • a lack of strength in the legs and hips
  • people who are recovering from hip, or knee, replacement surgery
  • very frail people


It is very common for the elderly to use them in some form.

My introduction to them came prior to my mother having hip replacement surgery some 18 months ago, and I saw one in the flesh for the first time, and was rather underwhelmed at the build quality.

Knowing that my mom was going to have to have some aid of this type for the toilet, we had, in the first instance, purchased a seat which locked onto the bowl with a few plastic bolts.

You simply lifted up the seat and lid of the toilet, and then pushed the white, tire like form, down over the rim of the toilet bowl. And after that  tightened a plastic kind of bolt on each side, securing it to the toilet bowl.

I tested it, and instantly thought that it was completely inadequate for the needs of a 90 year old lady post-hip surgery, and my mom wouldn’t even sit down on it, as she thought it was just too unsafe.

We then bought a portable bedside commode, which is a fully adjustable metal frame with a removable potty, and a seat with a lid.

Much to my mom’s delight, we discovered that it was way higher than our toilet, and could be placed above the bowl at varying heights, once the potty part of the commode had been removed.

I was later thrilled to see that in the hospital they were using a similar frame over the toilet after my mom’s surgery, and that mom, and I, received full instructions from the nurses and physical therapist, on how to correctly and safely use it.

My mom still uses the portable commode over the toilet, and we have been able to adjust the height for her, slowly lowering it as she got stronger.

It has big armrests and a frame that she can easily hold onto, to guide herself back into position. My mom has issues with eye sight and balance to contend with, and so she finds the frame helps her with these.

What are the different types of raised toilet seats ?


Raised toilet seats can be sorted into a few basic categories –


  • more temporary seats which can be easily put on and taken off a toiket very quickly, but which are not a long term solution
  • seats which have different side-locking and front locking mechanisms and which are rather more secure
  • tall seats and risers which actually bolt onto the toilet using your existing toilet bolt hole – these are very solid and offer one of the more longterm solutions for a rasied toilet seat
  • raised toilet seats which slot onto the bowl, but also have legs
  • safety frames with raised toilet seats which are placed over and above the toilet
  • bedside commodes which can be placed over the toilet and used as a raised toilet seat

How to install a raised toilet seat ?


Lets’s take a look at each type of seat and see how they are installed with a toilet.


How to install Bubble seats

Bubble seat raised toilet seat

Bubble seat raised toilet seat - underside

Bubble seats – this is a type of seat which simply slots onto the toilet with out any type of fastenings, locks or brackets.


To install –


  • remove your toilet seat and lid
  • place the bubble seat over the rim of your toilet and push down hard
  • it fits both elongated and standard toilets


The seat is made of a compressed foam and grips the toilet bowl.


Examples of this type of seat are –


The NRS Comfort raised toilet seat

Herdegen Contact Plus 5 inch raised toilet seat

Yunga Tart 4 3/4 inch raised toilet seat


The seats  –


  • are not height adjustable
  • have no armrests
  • have no bolts, clamps or locks to fix them to the toilet bowl
  • have a weight capacity


Once again without armrests and, in this case no bolts or fixings to speak of at all, I certainly wouldn’t use this for my elderly loved ones, not even with a safety frame. 

How to install Clip On raised toilet seats

Clip-on raised toilet seat - topside

As the name would suggest, these are toilet seats which simply clip into your existing toilet seat.

They are not a complete circle, or oval, but have a small opening at the front end – like a horse shoe, or a letter “C”.

This allows the user to push these open ends together, to lower the inner edge of the “clip-on” seat into the opening in their existing toilet seat.

When let go, the two open ends of the “clip-on” pull apart again, and the clip on seat just clips onto your toilet seat.

There are no bolts, no clamps, or locks, the seat is supposed to hold itself in place through tension.

You are going to want to be very careful with checking the weight limit on these seats to avoid accidents.


Some examples of this are –


  • Ability Suprtstore 4 inch Clip On Raised Toilet Seat
  • Performance Health Novelle 4 inch Clip On Raised Toilet Seat


There are no armrests, so there is nothing to hold onto if you are frail, not supple, or have any balance issues.


Seats with side fixings – another type of elevated, or raised, toilet seat uses side fixings – a type of bolt clamp – to grip the bowl on either side towards the rear of the seat, and at the front there is usually a bracket.


To install –


  • remove the toilet seat and lid from your toilet
  • place the elevated seat over the rim of your toilet bowl
  • insert the fixing bolts into the slots on the side and tighten


These seats are –


  • bought with or without lids
  • not height adjustable
  • have no armrests
  • standard or elongated
  • for different weight capacities


Examples of this system are –


Aquasense 4 inch raised toilet seat with lid

Vaunn Medical Clamp-on 4 inch raised toilet teat

Carex 4 1/2 inch raised toilet seat

Homecraft Savanah 2, 4, 6 inch raised toilet seats with, or without lids


As with all seats without arms, I would only recommend these for people who have good balance, and don’t use a height that has the user’s feet in the air, or with just the toes touching, as this can lead to a fall when getting up.

I think that a toilet safety frame, or grab bars, again would be a good addition to make it all a bit safer, and to give the person support as they stand up, or sit down.

There is actually only one brand that makes these seats, but they are markedly different from the other types.


To install –


  • lift the existing seat and lid into the upright position
  • the raised toilet seat placed on the toilet bowl rim
  • there is an inner lip which drops several inches into the bowl to stop it wobbling
  • there are four plastic clips which are pushed in to grip the outside of the toilet bowl, exerting equal pressure around outside the toilet bowl
  • models I, II, III do not have armrests
  • models IV and V come with armrests
  • VI and VII come with armrests and legs


The examples of these seats are –


Herdegen Clipper I 4.3 inch raised toilet seat, Prod. No. 500400

Herdegen Clipper II 4.3 inch raised toilet seat, Prod. No. 500410

Herdegen Clipper III 4.3 inch raised toilet seat w/ lid, Prod. No. 500411

Herdegen Clipper IV 4.3 inch raised toilet seat w/ swing-up armrests, Prod. No. 500420

Herdegen Clipper V 4.3 inch raised toilet seat w/ swing-up armrests and a lid, Prod. No. 500421

Herdegen Clipper VI 4.3 inch raised toilet seat w/ adjustable frame and armrests, Prod. No. 500430

Herdegen Clipper VII 4.3 inch raised toilet seat w/lid and adjustable frame and armrests, Prod. No. 500431


How to install front locking rasied toilet seats

Front locking raised toilet seat without handles

Front locking raised toilet seat on a toilet

Front locking systems – front locking seats have a clamp at the front of the seat with a knob, and the sides go down a few inches on the inside edge. On the back there is also a lip which is to be placed under the inside edge of the toilet bowl rim to give added stability.

They come in a range of heights, depending on the brand, from 4 – 5 inches.


To install –


  • remove the existing seat, and lid, from your toilet if it is in your way
  • place the seat over the toilet and into the bowl
  • guide the back of the seat into the toilet so that the lip at the back goes under the rim of the toilet
  • line the seat up to where you would like it
  • tighten the knob on the front, and the seat is clamped on to the bowl


A few other points to consider –


  • most of these seats have armrests
  • some armrests are adjustable
  • some armrests are removable
  • the seats all have weight capacities
  • the seats are compatible with almost all types of toilet


Some examples of this type –


Carex E-Z Lock 5 inch raised toilet seat with arms

Medokare 4.5 inch raised toilet seat with arms

Vive 5 inch raised toilet seat with padded handle

Drive Medical Premium raised toilet seat with lock and padded armrests


Of all the elevated and raised toilet seats, the front locking are apparently the most solid.

The fact that they have armrests means that you have something to grab onto before you sit back.

If there was a grab bar next to the toilet as well, I think that this is a good system for all but the most elderly and frail.


How to install raised toilet seats with legs

Raised toilet seat with legs

This is a raised toilet seat which is wider than the toilet bowl, and has 4 legs.

The seat is resting on both the toilet bowl and on the legs.

The design stops any wobbliness, gives a wider distance between the armrests for a larger person, and makes the seat more sturdy in general.


To install –


  • the legs have to be adjusted to the height of the toilet bowl
  • the seat itself adds about 4 1/2 inches in height to the toilet on most models
  • depending on the brand the raised seats may attach differently to the bowl, some just slot in and others slot in and have a front locking bolt, but with four legs there is no real risk of it coming off
  • these raised seats can take greater weight than those without legs and are more stable


The armrests are a lot easier for an elderly person to use, and as I have seen with my own mom, when a seat has legs it gives the person more confidence when using it, as there is no problem with the seat moving around.


Some examples of raised toilet seats with legs –


Maddak Extra wide Tall-Ette elevated toilet seat w/ aluminum legs, Prod. No. T725881000

Maddak Extra wide Tall-Ette elevated toilet seat with steel legs, Prod. No. T725882000

Mobb 4.5 inchRaised Toilet Seat With Legs Prod. No. MHRTSL

Herdegen Clipper VII 4.3 inch raised toilet seat w/lid and adjustable frame and armrests, Prod. No. 500431


How to intsall “Tall Seats” or “Seats with Spacers”

Spacer raised toilet seat with lid

Spacer raised toilet seat without lid

The seats have small spacers on their under side, and come in 2 inch, or 3 inch high models.


To install –


  • remove the existing toilet seat and lid of your toilet
  • place the new seat and lid in the same position as the old one
  • re-attach the seat with bolts using the existing holes


The seats are available –


  • with or without lids
  • can be open or closed at the front
  • do not have armrests
  • the height is not adjustable
  • will have weight capacities you will need to check


Due to the lack of armrests, I again wouldn’t suggest these as viable for anyone who is less than strong and with good balance, unless you have grab bars, or a toilet safety frame, to help the person backing up to the toilet to sit, and to hold onto when they get up again.

If you do get this for someone, don’t have them use it if their feet are dangling in the air, or their toes only are touching the floor, as they won’t have proper balance when they stand up, and there are no handles for support.


An example of one of these seats is –


  • Centoco 3L440STS-001 raised toilet seat with lid

How to install toilet risers

Basic riser

Hinged riser

Riser with armrests

Alignment of a riser toilet seat, lid and toilet

Riser installed on a toilet under the seat and lid

These oval ring-shaped blocks of plastic which come in a range of heights from 2 to 4 inches.

The riser will raise your toilet seat by the amount of its height.

Risers are extremely solid as they are bolted onto the toilet using your existing bolt holes through which the seat and lid are attached – going under your existing seat.


To install –


  • first remove the seat and lid from your toilet
  • align the holes in the riser to the existing bolt holes on your toilet
  • place your toilet seat and lid on top of the riser and make sure all the holes line up
  • take the new extra long bolts which came with the riser and thread them through and attach the nuts to the bolts on the underside of the toilet
  • never over tighten the nuts to the bolts, as the toilet is ceramic and can break


A few other points to consider –


  • risers can have a hinge in them just as seats do, making it possible to lift and clean underneath them
  • I am not aware of a riser with adjustable height, but there are risers with adjustable arms
  • you must check whether your toilet is standard, or elongated, before you buy a riser, and buy the corresponding model


Some examples of these risers are –


  • Nova 3 1/2 inch toilet seat riser
  • Maddak 4 inch hinged seat riser
  • Maddak 3 1/2 inch toilet seat riser with safety arms


Risers are very solid, and with arms and a grab bar on the wall next to the toilet, they are a safe option, in my opinion, for people who are quite strong and still have relatively good balance.

How to install safety frames with raised seats

Toilet safety frame with elevated seat placed over a toilet

A safety frame is a metal frame – aluminum or steel – with an integrated raised seat, which you can easily place over the toilet – not to be confused with toilet safety frames which are only a frame to hold onto when you use the toilet.


To install –


  • put the seat and lid on your toilet in the upright position
  • place the frame over your toilet


A few points to consider –


  • the height on all models is adjustable
  • the width on some models is adjustable
  • the weight capacity is greater than on the plastic clamp on seats
  • there are bariatric frames for heavier people
  • you can get mechanized frames or toilet lifts which assist in sitting and standing
  • all the frames have armrests and some are adjustable – they are larger and more sturdy than on the plastic clamp on seats
  • the frame takes the weight, not the plastic seat


Some examples of safety frames with raised toilet seats are –


Maddak Tall-Ette elevated toilet seat with legs 

PCP raised toilet seat and safety frame 2-in-1

MOBB elevated toilet seat and frame

Aidapt President raised toilet seat and frame 

Lattice commode toilet seat and frame 


Some examples of toilet lift –


The Uplift Commode

Easy Access Tilt Toilet lift (this model is slightly different as it doesn’t have the frame on the floor, but it is secured to the toilet in a way that it won’t come off)

The Liftseat Powered Toilet Lift

The Drive Solo Lift with Arms


If you are at all worried about the physical capacities of your loved ones and aren’t sure about their balance, strength or mobility, I wouldn’t hesitate to get them a frame with a raised seat, instead of one of the other types.

If you are the caregiver to someone who is very frail, or who has a muscular  condition which makes movement extremely difficult, and painful, you may want to look at the toilet lifts.

The first two toilet lifts are a lot more accessible in terms of price, than the latter two, which are very sophisticated and pricey pieces of equipment.

How to install bedside commodes as a raised toilet seat

3 in 1 bedside commode placed over a toilet

Now to my mom’s favorite, the portable bedside commode.

The portable bedside commode is also known as a 3-in-1 commode, or as an all-in-1 commode.

It is a metal chair frame with a toilet seat and a potty, which can be

(a) placed at the bedside, to be used as a commode,

(b)  over and around the toilet as a safety frame to hold onto when you sit down, or get up, or

(c) as a frame with a raised toilet seat


To install as a raised toilet seat –


  • place the existing toilet seat and lid of your toilet in the upright position
  • remove the potty from the commode
  • for the tightest fit, remove the backrest
  • place the commode over the toilet with its seat on


Some other points to consider –


  • you can adjust the height
  • you can adjust the width
  • you can adjust the armrests on some
  • you have bariatric commodes for heavier people
  • you have transfer commodes with wheels


Some examples of this type of commode are –


Drive Medical heavy-duty bariatric commode

Drive Medical steel folding bedside commode 

UltraCommode bedside commode


This is pretty much perfect, in my opinion, for an elderly person who needs a bit of assistance with their balance, and who doesn’t have great mobility.

Should you decide that you would like to know more about how to use a bedside commode as a raised toilet seat, which types you can use over a toilet, and how to set one up, you can find all the relevant information, and more, in my article “Can A Bedside Commode Be Used Over A Toilet ?”

How to clean raised toilet seats ?


To clean the plastic elevated and raised toilet seats –


  • use a non-abrasive cleaner, or detergent, and warm water to wash down your seat
  • rinse the seat well and wipe off with a non-abrasive cloth
  • if your seat has any grips or plastic parts on any armrest, make sure that it is still firmly in place and doesn’t rotate
  • check around any fixings, clamps or other locking mechanisms, to make sure that there are no cracks each time you clean


To clean a frame or commode


  • start by removing the seat lid and splash guard and cleaning them one by one
  • make sure to pay particular attention to the armrests and seat, as this is where the body has the most contact
  • the underside of the seat, the metal bracket holding the splash guard and the splash guard are the areas which can get soiled, so they have to be thoroughly cleaned
  • rinse and wipe off with a dry cloth
  • then clean the frame and wipe and dry it off
  • check that the seat is not cracking anywhere
  • clean the plastic parts with a non-abrasive cleaner, or detergent, and warm water
  • rinse and wipe off with a non-abrasive cloth


What is the best raised toilet seat after a hip replacement ?


The choice of the best raised toilet seat after a hip replacement really depends on the age of the person involved, their size and general health.

For elderly adults, I would advise, based on experiences with my elderly Mom, a safety frame with a raised seat, or a portable bedside commode with the potty removed.

Younger adults who have no mobility or strength issues may be able to use some other types of raised toilet seats without putting themselves at risk of a fall.

If you want to learn more on the specific topic of seats for after a hip replacement, I have a specific article on the subject, “Best Raised Toilet Seats After A Hip Replacement”, in which I outline my preferred toilet seats for different types of individuals and situations –


  • best raised toilet seats after a hip replacement for an elderly senior
  • best raised toilet seats after a hip replacement for a larger elderly senior
  • best raised toilet seats after a hip replacement for a younger senior in good shape
  • best raised toilet seats after a hip replacement for larger, younger seniors


My post also discusses  –


  • do you need a raised toilet seat after hip surgery
  • how to sit on a raised toilet seat after hip surgery
  • for how long would you use a raised toilet seat after hip surgery
  • does Medicare cover raised toilet seats
  • how to choose your raised toilet seat



It is also a good idea, in the first weeks after the operation, to use a walker in addition to the raised seat.

That way, your parent has something to hold onto when they are standing, and backing up to the toilet, and secondly, they can transfer their weight from the toilet armrests over to the walker.

It is also very important for the person having the surgery, and for their caregiver, to learn how to sit down and to stand up after the surgery. If they can do this properly, it will avoid unfortunate strains, or injuries.

If you want to learn how to sit down and stand up properly from a raised toilet seat or bedside commode with a walker, I have a post which outlines how it should be done, and you can find that here – “Using A Bedside Commode: An Illustrated Guide”.


How to choose a raised toilet seat for an elderly person ?


How to decide what type of raised seat is needed ?


As well as considering how solid a raised toilet seat is, you also need to consider how secure and stable your elderly loved one is, and also if they will need any extra features to make sitting safer.


To choose which type of raised toilet is suitable for your loved one, you want to consider –


  • the environment where the seat is going – space ? Clutter ? Access ?
  • the health of your elderly loved one
  • any particular medical reasons for using the raised toilet seat


To help you, I have a free PDF checklist of possible questions that you can download below.

Here are the type of questions that you may want to ask yourself  –

Environment in the bathroom


  • how much space is there ?
  • has all unnecessary clutter which may cause a fall been removed ?
  • does your loved one know how to sit on a raised toilet seat using a walker?
  • is there a need for extra safety equipment to make your loved one feel confident about using a raised toilet seat ?


What is your loved one’s state of health ?


  • why is your loved one using a raised toilet seat ?
  • is it for long term or short term use ?
  • if it’s a short term, do you still need armrests etc. ?
  • if it’s long term, you may want to get the most solid seat from the start
  • will your loved one need help using the raised seat ?
  • are there other mobility issues as well as sitting and standing ?
  • how elderly and frail is your loved one ?
  • how good is your loved one’s balance ?
  • is your loved one’s vision okay, or are there problems ?
  • how strong is your elderly loved one ?
  • is your loved one’s grip strong ?
  • how good is your loved one’s coordination ? – seats with big armrests are easier for the elderly
  • how confident is your loved one about sitting and standing – are they nervous about using a raised toilet seat ?
  • how confident are they about moving backwards ?
  • can you make them more confident with a raised the seat ? – a more stable seat with armrests to hold onto will increase a person’s confidence
  • is your loved one able to clean themselves afterwards ? – if not, you may want to buy a drop arm bedside commode which permits side access, or an open front raised toilet seat, so they can pass their hand underneath without getting up
  • does your loved one sit back with quite a jolt ? – if so, you need a solid model with good armrests
  • how is your loved one’s leg strength ? Do they need armrests to help push themselves back up with ?
  • is your loved one a larger person ? If so, do they need a bariatric seat ?
  • does your loved one need a wide seat ? – if so you will have to get either a wider raised toilet seat with legs like the Maddak, an extra wide bariatric commode, a bariatric safety frame with raised seat, or a bariatric bedside commode which you place over the toilet which comes in extra wide models

Medical reasons for needing a raised toilet seat


  • if there are medical issues, are there very specific problems which will affect your choice ?
  • do you need to talk to your loved one’s doctor or nurse ?
  • if your loved one has eye conditions, will they need extra grab bars or bigger armrests ?
  • if it is for a long term medical condition, what does that condition require ?
  • is the seat for a younger person who has had a hip, or knee, replacement, and who has good strength and balance on their good leg ?
  • is the seat for an elderly person with a hip, or knee, replacement, and who maybe has poor strength and balance ?


Hopefully these questions will give you the answers you need, and maybe help you find more questions you need to ask.
