A comfortable, capable chair for people who are out and about every day

If your electric wheelchair is how you get to work, the shops, the pub and back, you need one that rides well, lasts and fits you properly. The Invacare Storm4 is a robust, rear-wheel drive electric wheelchair (also known as a powerchair) with springs and shock absorbers on all four wheels, so everyday outdoor journeys feel smooth rather than jarring.

Its Modulite seating can be set up around your body, with an optional seat lifter and seat tilt, and the REM400 touchscreen makes driving and adjusting the chair simple. It's a chair built for a full, active life, indoors and out.

✅ Key Features & Benefits

• Suspension on all four wheels
  Four individually adjustable springs with shock absorbers soak up kerbs, potholes and rough paths, so far less of each bump reaches your back, neck and joints.

• Up to 36 km (22 miles) of range
  Large 73.5 Ah batteries give you a full day out without watching the battery gauge.

• Modulite seating set up for you
  Seat width (380–530 mm), depth and height adjust to your body — better posture and comfort if you sit most of the day.

• Seat tilt up to 25° and backrest recline
  Shift your weight and lean back to ease pressure on your bottom and lower back and rest when you need to.

• Optional seat lifter
  Raise yourself to reach cupboards, worktops and shelves, or talk to people at eye level.

• REM400 touchscreen with Bluetooth
  A clear 3.5" colour screen that needs very little pressure to use — helpful if your hands are weak — and connects to up to three devices.

• Choice of 6 or 10 km/h motors
  Roughly 4 or 6 mph, so the chair can be set up for mostly indoor use or quicker outdoor trips.

• Crash tested
  Can be used as a seat in a suitably adapted vehicle.

Colours available

Blue, Black and Champagne as standard, with Transparent Red, White and Olive Green as options.

Who it suits best

• You use your chair outdoors every day and want a smooth ride
• You spend long hours seated and need seating set up for you
• You'd benefit from tilt, recline or a seat lifter
• Users up to 150 kg (23.5 stone)

Worth knowing before you buy

The Storm4 is a full-size chair — around 174 kg on average depending on configuration, with a turning circle of 1770 mm — so it needs reasonable space at home and does not fold for a car boot. If your home has very tight corners, a compact or mid-wheel drive chair may turn more easily. For heavier users, look at the Storm4 MAX; for rough tracks and countryside, the Storm4 X-plore is built for all terrain.
