Bariatric wheelchairs

Bariatric wheelchairs, also sometimes referred to as “heavy duty wheelchairs”, are designed and constructed with the larger and heavier person in mind. As a result they have much more substantial frames, stronger wheels and larger (particularly wider) seats than regular wheelchairs.

Weight capacity and seat size

With both a larger seat and a stronger frame, a heavy duty bariatric wheelchair can accommodate an individual of almost any weight. This means that these chairs can carry a larger individual than a heavy duty mobility scooter and some manufacturers produce chairs that can accommodate a person of up to 1000 pounds in weight (71 stone).

Additionally, these bariatric wheelchairs come in a range of different seat sizes, often directly related to the load bearing capacity of the chair. The seat sizes (i.e. seat widths) typically range from about 22 inches to 34 inches or more and increase at 2 inch intervals. As a result it is possible to find a wheelchair with a load bearing capacity and seating width to comfortably accommodate almost anyone.

More features

In addition to a larger sized overall wheelchair and seat, the bigger person will usually benefit from a more padded seat or cushion. Extra wide bariatric wheelchair Today many manufacturers offer the option of different seating cushions and a number include a visco elastic memory foam filling which many people feel offers superior comfort and support. Memory foam cushions can be flat or contoured to the shape of the lower torso and upper legs.

Variable seat height and armrest height selection enables the bariatric wheelchair to be matched to the person using it. Heavy duty armrests also make lifting oneself out of the chair an easier and more secure activity.

Hydraulic operation of the backrest is available on some chairs and most will have adjustable settings for the backrest height, seat depth, the angle between the seat and the backrest, and the angle (or tilt) between the seat and the floor.

The angle between the seat and the backrest is particularly important for larger people as this angle tends to be greater (more tilted) for larger bodied individuals who would otherwise feel compressed when seated in an upright posture. The result is that by taking advantage of these numerous adjustments a comfortable seated position can be achieved for almost anyone.

Further additional features can include padded leg supports for the back of the calves. These keep the legs in position and offer a balanced even support to the lower legs. Footrest are also included and these are often larger than standard and are adjustable for length and height.

An IV holder and (or) an oxygen tank holder are usually options that can be fitted to most wheelchairs.

Other design features

Like a standard wheelchair, the bariatric version places most of the weight over the larger fixed rear wheels. These wheels will be harder than normal to accommodate the extra weight. However, because the body’s weight distribution can also see a significant amount of weight in the legs of larger people, the front wheels are positioned further forward than normal. This increases the stability of the chair during motion and makes it easier to get into and out of the chair.
