Best Chair Raiser UK: Furniture Risers for Easier Standing

How High Should a Chair Raiser Lift My Chair?

A chair raiser should lift the seat so your hips sit slightly higher than your knees when you sit with feet flat on the floor. Measure from the floor to the back of your knee while standing in your usual shoes, then measure the current seat height of your chair at the front edge. The difference shows roughly how much lift you need. Most raisers add around 5 to 15 cm, and some screw type designs adjust in smaller steps. Do not raise the chair so far that your feet dangle, as this reduces stability and puts pressure on the back of the thighs. Check the armrest height too, because arms that end up too high can lift your shoulders. Try sitting with firm cushions or books under the legs first to test the height.

How Do These Chair Raisers Compare?

The table lists each chair raiser with who it suits and its main feature. Measure your knee height and chair legs before comparing them.

Which Chair Raiser Fits My Chair Legs?

The right chair raiser depends on whether your chair has round legs, square legs, castors or a solid base. Cup or elephant foot raisers suit round and square legs, with an opening that should be slightly wider than the leg. Measure each leg at the base, across its widest point, and compare with the inner cup size in the listing. Chairs on castors need castor cups or raisers designed to hold a wheel without rolling. Solid based sofas and recliners often need a frame or platform raiser that sits under the whole chair. Screw raisers fix into the threaded holes of some chair legs. Check the floor contact area too, because wider bases spread weight better on carpet. If your chair is a riser recliner, ask the maker before raising it.

Are Chair Raisers Stable on Carpet and Hard Floors?

Chair raisers for elderly users are stable on both carpet and hard floors when they suit the leg shape and sit flat, with every leg raised by the same amount. Wide, solid bases stay steady on thick carpet, while rubber or felt pads stop raisers sliding on wooden or tiled floors. Compare stability by pressing down on each arm of the chair once fitted; it should not rock, tilt or move. Push the chair from behind as well to check it does not slide forward when you sit down heavily. Avoid stacking different raisers, which can wobble. If the floor is uneven, adjustable screw raisers help level the chair. Check the stated weight limit, covering both the chair and the person. Recheck the fit every few weeks, as carpet compresses and legs can shift.

How Do I Fit Chair Raisers Safely?

Fit chair raisers with two people where possible, as tipping a heavy armchair alone can strain your back. Clear the area first and lay a towel on the floor to protect it. Tilt the chair gently backwards, slip the raisers under the front legs, then lower it and do the same at the back. Make sure each leg sits fully inside its cup or on its platform, with no part overhanging the edge. Check all four raisers are the same height, so the chair sits level. Once fitted, press down on each arm and the front of the seat to check it does not rock or slide. Sit down slowly the first time and test standing up again. If the chair has a reclining mechanism, check it still moves freely without catching on the raisers. Recheck the raisers each month, as carpet compresses. If you are not sure how high to go, ask an occupational therapist for a home assessment, which many local councils offer.

Frequently Asked Questions

How High Should a Chair Raiser Lift?

A chair raiser should lift the seat enough that your hips sit slightly higher than your knees, with feet flat on the floor. For most people this means an extra 5 to 15 cm. Measure your knee height and the current seat height to work out the lift you need.

Are Chair Raisers Stable?

Chair raisers are stable when they match your chair legs, sit flat and raise every leg by the same amount. Wide bases suit carpet and rubber pads suit hard floors. Press down on the chair arms after fitting to check it does not rock or slide.

Will Chair Raisers Fit Any Chair?

Chair raisers do not fit every chair, as leg shape, size and base type vary. Measure each leg across its widest point and compare it with the listing. Solid based chairs or sofas often need a platform style raiser rather than individual cups.

What Chair Height Is Suits Older People?

The best chair height lets an older person sit with feet flat, knees bent at about a right angle and hips level with or slightly above the knees. This makes standing up easier. An occupational therapist can measure and recommend the right height.

Do Chair Raisers Damage Carpets?

Chair raisers can leave marks on carpet over time, as the weight is concentrated on a small area. Wider bases spread the load and reduce marks. Moving the chair slightly every few months and using carpet protectors under the raisers can help.
