Description
The Drive Sentra EC Extra-Extra-Wide Bariatric Wheelchair is the chair for riders every standard line leaves out — seats up to a true 30 in wide and a frame rated to 700 lb, reinforced at every point that carries weight. Desk-length arms let you pull up to tables and counters, and Drive sells this class the way facilities buy it: as the base chair, with front riggings ordered separately so you fit exactly the footrests or elevating legrests the rider needs. If you have been told to "look at reinforced models," this is the reinforced model.
- 700 lb capacity on a reinforced carbon steel frame — the top of Drive's Sentra line
- Seat widths of 26 in, 28 in and 30 in with a 20 in depth
- Desk-length armrests, detachable, extra-large padded
- Base chair sold without front riggings — add Drive PH-SF footrests or PHELR elevating legrests to fit the rider
- Triple-coated chrome finish over steel spoke wheels and heavy-duty flat-free casters
Built for Riders Standard Chairs Turn Away
Most bariatric chairs top out at 450 or 500 lb and 24 in of seat. This extra wide wheelchair starts where they stop. The carbon steel frame adds reinforced gussets at every weight-bearing point, a reinforced side frame, caster journals and dual cross bars, and extra-heavy-duty front forks — structure you can feel the first time you sit down: no flex, no creak, no negotiation. The triple-coated chrome finish shrugs off daily knocks, and the reinforced nylon upholstery is made for real-world use, year after year. Desk-length arms keep tables and work surfaces within reach, then detach for side transfers.

It is rated to 700 lb — the highest in Drive's Sentra line — on a reinforced carbon steel frame with a triple-coated chrome finish.

Minimal by design: wipe the tires occasionally with a damp cloth and replace them if severely worn or cracking; inspect the front casters periodically and lubricate the stem and wheel bearings occasionally, tensioned so there is no play yet the wheels roll freely.
