Strong, supportive and comfortable — built for bigger users

If standard electric wheelchairs have felt cramped, or you've worried about whether a chair is really built to carry you, the Invacare AVIVA RX40 HD is designed with you in mind. It carries users up to 160 kg (25 stone) on a wider, sturdier base, with heavy-duty seating that gives you room to sit comfortably.

It's still an everyday electric wheelchair (also known as a powerchair) for home and outdoors: smooth CTC suspension, clear LiNX controls, speed options up to 8 mph and seating with tilt and recline, so you can spend the whole day in it and feel well supported.

✅ Key Features & Benefits

• Carries users up to 160 kg (25 st)
  A chair rated properly for your weight gives you peace of mind every time you sit down, and puts less strain on the frame and motors over the years.

• Wider 635 mm base and Modulite HD seating
  More room in the seat and a stable footprint, so you sit comfortably without feeling squeezed or perched.

• CTC suspension
  Keeps the chair steady and the wheels gripping on kerbs and uneven paving, so the ride is smoother on your back and joints.

• Tilt and recline
  Tilt up to 15° and recline up to 30° to take pressure off your bottom and lower back and to rest during the day.

• More powerful 120A power pack
  Gives the drive the extra strength needed for heavier users, so the chair doesn't struggle on slopes.

• Speed options up to 8 mph
  Motor options of 6, 10 or 12 km/h, so you can choose a gentle pace or something quicker for longer trips outside.

• Larger front castors
  Roll more easily over thresholds and rough ground.

• Seat lift option and crash tested
  Raise the seat to reach worktops or transfer, and travel seated in a suitably adapted vehicle.

Who it suits best

• Users up to 160 kg (25 stone)
• You need a wider, roomier seat
• You spend most of the day in your chair, indoors and out
• You'd benefit from tilt, recline or a seat lift

Worth knowing before you buy

The HD's 635 mm base is wider than a standard chair, so measure your doorways and hallways first — we're happy to help. It's a full-size chair that doesn't fold for a car boot. If you weigh under 136 kg (21 stone) and need a narrower chair for a tight home, the standard RX40 Modulite will usually suit better; for even higher weight limits, look at a dedicated bariatric electric wheelchair.

Questions customers ask us

Will it go through my doors?
The base is 635 mm wide, so some narrower internal doors can be tight — we'll measure up with you.

Can I use it in a wheelchair taxi?
Yes, it's crash tested for use as a seat in a suitably adapted vehicle.

Can I try one?
Yes — we can arrange an assessment and demonstration so the seating is set up for you.
