How bariatric ratings compare
| Rating | In kg | Typical seat width | Typical footrest limit |
|---|
| 25 stone | 159kg | 56 to 61cm (22 to 24in) | 20 stone or less |
| 30 stone | 190kg | 56 to 66cm (22 to 26in) | Typically 20 stone |
| 35 stone | 222kg | 61 to 66cm (24 to 26in) | Typically 20 to 25 stone |
| 40 stone | 254kg | 64 to 76cm (25 to 30in) | Typically 25 stone |
| 50 stone | 318kg | 71 to 81cm (28 to 32in) | Typically 25 stone |
These are typical ranges for chairs on the UK market. Every model is different, so always check the supplier’s figures for seat weight, footrest weight and seat size.
How to read a weight rating
Every riser recliner is built for a maximum user weight. It is the load the frame, mechanism and motors are designed to lift, recline and lower safely, many times a day, for years. On a bariatric chair it is the single most important figure on the specification, because it decides which chairs are safe for the user to choose from.
Ratings are usually given in stone and kilograms, and bariatric chairs are commonly sold in bands of 25, 30, 35, 40 and 50 stone. A higher rating means a heavier frame, stronger motors and a more robust mechanism. It usually brings a wider seat too, although the seat size and the weight rating are separate figures and both need checking.
Seat limit and footrest limit
Most chairs have two weight limits. The seat limit is the maximum user weight for the chair. The footrest limit is the maximum weight the raised footrest can carry, and it is almost always lower. On bariatric chairs the footrest is typically rated somewhere around 20 to 25 stone, even when the chair itself is rated far higher.
The footrest limit matters because the footrest carries the weight of the legs when raised, and some people rest heavily on it or sit on the end of it. Ask every supplier for both figures in writing.
Why choose a rating above the user's weight
A chair rated close to the user's weight works its frame and motors hard every time it lifts. Choosing a rating with some headroom leaves room for weight changes and for a visitor sitting in the chair, and helps the chair last. Suppliers will often recommend going up a band if the user is near the top of one.
Headroom also protects the warranty. Using a chair above its stated limit puts extra strain on the motors and mechanism and may affect what the manufacturer will cover.
Weight rating and seat size work together
A chair can be rated well above the user's weight and still not fit. If the seat is too narrow, the hips press against the arms; if it is too deep, the user cannot sit back properly; if it is too low, standing up is harder even with the rise function. Always check the seat width between the arms, the seat depth and the seat height alongside the rating.
Many bariatric suppliers will build the seat to the user's measurements. Our measuring guide shows how to take them in about five minutes.
Choosing between two ratings
If the user sits between two bands, compare chairs at both. The higher rating usually brings a wider seat and a stronger build, while the lower rating may offer more styles at that seat size. Ask suppliers to quote for both so you can see the real differences in fit, features and aftercare.
Think about how the chair will be used too. A chair that will be the main seat in the house, used for many hours a day, benefits most from extra headroom.
Made to measure at every rating
From around 30 stone upwards, many chairs are made to order, with the seat width, depth and height set to the user. A made-to-measure chair takes longer to arrive than a stock model, but it is often the best way to get a comfortable fit for a larger frame.
How the rating affects what you pay
Each step up in weight rating needs a stronger frame, higher-rated motors and usually a wider seat, so higher-rated chairs generally cost more to make. That is not a reason to choose the lowest rating you can. A chair working at the very top of its rating every day is under more strain, and a cheaper chair that does not fit is not good value. The fairest way to compare is to ask suppliers to quote for the same rating, seat size and features, then compare what each includes for delivery, warranty and aftercare.
Before you ask for prices
- Note the user’s weight and choose a rating comfortably above it.
- Take the user’s seat measurements with our measuring guide.
- Decide whether you want single or dual motor, and any extras such as a battery back-up.
- Measure the doorways and the room where the chair will go.
- Check whether the user may be eligible for VAT relief.
With those details ready, suppliers can recommend the right chair first time, and you can compare their quotes side by side.
Not sure which rating you need?
If you are unsure, start with the user’s weight and add some headroom, then check the seat size. Suppliers can help too: when they contact you with prices, tell them the user’s weight and measurements and ask which rating they would recommend and why. Many will bring a chair to your home so the user can try it before you decide, which is the most reliable way to be sure of the fit.
