  • Lightweight weighs no more than 36 lbs. For anyone looking for an ultra-lightweight wheelchair, the K4 is for you. The lightweight folding wheelchair weighs between 32 to 36 lbs, making it perfect for anyone with weak strength or in need of a portable wheelchair.
  • Supports up to 300 lbs. The manual wheelchair sports a cross-brace aluminum frame making it a heavy-duty wheelchair. This ProBasics wheelchair is guaranteed to last.
  • Height adjustable seat from 17" to 20". Having the right seat height is essential. The lightweight foldable wheelchair offers users more comfort with an adjustable seat.
  • Easy to clean nylon upholstery. The comfortable materials make cleaning easy. They're both mold and mildew resistant.
  • Comes with a 2" seat extension. Most standard wheelchairs don't offer much-extended comfort. This light wheelchair features a built-in 2" seat extension for an upgraded level of comfort. The handicap wheelchair combines convenience, comfort, and a better mobility method.
  • Adjustable anti-tippers for safetyFor anyone in need of everyday wheelchair assistance, safety is essential. The anti-tippers keep the wheelchair upright and prevent it from falling backward. This feature added even more safety when going up or downhill.
  • Added comfort with height adjustable padded flip-back armrests. Don't settle for wheelchair discomfort. The armrests offer an additional layer of comfort, can flip-back when not in use, and can be removed to convert into a compact wheelchair. They are height adjustable from 10" to 14" to accommodate a seat cushion.
  • Easy push-to-lock wheel locks. Keep the adult wheelchair in place when needed. Perfect for when sitting in place or on an uneven surface.
  • Available in multiple sizes. The lightweight, portable wheelchair comes in multiple sizes, from smaller to extra-wide wheelchair sizes. They include seat widths of 20" x 16", 18" x 16", and 16" x 16"

  • The seatback is height and angle adjustable. Adjust the disabled wheelchair's seat for even more comfort. It can be height adjusted from 16" to 18" and offers an angle adjust from 5 degrees to 20 degrees.
