Bariatric equipment is built and tested for higher weight capacities, usually from 400 lb up to 1,000 lb. Choosing the right piece comes down to four checks: weight capacity, seat width, doorway clearance and how the person transfers. This guide walks through each one, then covers the main equipment types. You can browse everything in one place in our bariatric equipment collection.
1. Weight capacity: leave a safety margin
Every product lists a maximum user weight. A good rule of thumb is to choose a rating at least 20% above the user's current weight. That margin covers the extra force of sitting down hard, shifting during a transfer, or carrying a bag on a rollator seat.
- User up to about 330 lb: a 400 lb rated item is usually enough.
- User up to about 400 lb: look at 500 lb rated items.
- User up to about 540 lb: look at 650 to 700 lb rated items.
- Above that: choose 800 to 1,000 lb heavy-duty (HD) models.
Weight capacity is a limit, not a target. Never exceed it.
2. Seat width: measure, then add room
Have the person sit on a firm chair and measure across the widest part of the hips or thighs. Add about 2 inches so clothing fits and the sides don't press on the skin. Bariatric wheelchairs come in seat widths from 22 inches up to 30 inches and more, and commodes and shower chairs list their seat width in the specs.
Too narrow causes pressure and skin problems. Too wide makes it hard to reach the wheels and can reduce stability, so don't oversize by more than a couple of inches.
3. Doorways and hallways: check the overall width
A wider seat means a wider frame. Before ordering a wheelchair, commode or mobile shower chair, measure your narrowest doorway with the door fully open, including the bathroom. Then compare it to the product's overall width, not its seat width. Many homes have interior doors around 30 inches wide, which can rule out some wide chairs.
If a doorway is tight, look at offset door hinges, a bedside commode instead of a trip to the bathroom, or a narrower model with a higher weight rating.
4. Transfers: plan how the person gets on and off
- Drop-arm commodes let the arm swing down so the person can slide across from a bed or wheelchair.
- Removable or desk-length arms on wheelchairs make side transfers and pulling up to a table easier.
- Tub transfer benches let the person sit outside the tub and slide in, instead of stepping over the tub wall.
- Seat height matters: knees level with or slightly below the hips makes standing up easier.
The main types of bariatric equipment
Bariatric wheelchairs
Heavy-duty frames, reinforced cross-braces and wide seats. Reclining models with elevating leg rests suit people who sit for long periods. See our bariatric wheelchair with desk arms and elevating leg rests (22 or 24 inch seat, 500 lb) and the DynaRide reclining wheelchair, or the full wheelchair collection.
Bariatric rollators
Wider seats, steel frames and larger wheels. Check the seat width and the handle height range. Browse rollators, including 500 lb and 700 lb models.
Commodes and shower chairs
Three-in-one commodes work as a bedside commode, a raised toilet seat or a toilet safety frame. Our bariatric drop-arm commode is a common choice for side transfers. For bathing, see shower chairs and bath benches, including the heavy-duty bariatric bath bench.
Beds, mattresses and overlays
Bariatric homecare beds and air mattresses spread weight to reduce pressure. Match the mattress width to the bed frame and check the combined weight rating.
Canes and walkers
Heavy-duty quad canes and wide folding walkers add stability for walking short distances. See the 500 lb heavy-duty quad cane and the walker collection.
Quick checklist before you order
- Weight rating at least 20% above the user's weight.
- Seat width = hip width + about 2 inches.
- Overall width fits through every doorway on the route.
- Transfer style planned: drop arms, removable arms or a transfer bench.
- Seat height lets the knees sit level with or below the hips.
Frequently asked questions
Is bariatric equipment only for people over 400 lb?
No. Many people under 400 lb choose bariatric models for the wider seat, extra stability or the safety margin.
Can I use bariatric equipment with my FSA or HSA?
Many items such as wheelchairs, walkers and commodes are commonly eligible. Check with your plan administrator for your specific plan.
Do you sell to nursing homes and facilities?
Yes. Facilities, hospices and DME providers can request volume pricing through our contact page.
