Merits P312A Dualer Elevating-Seat Power Wheelchair

The Merits P312A Dualer is a full-size power wheelchair built around a power-elevating seat and a drive configuration that the seller describes as offering front- or rear-wheel-drive handling. Its appeal is the combination of a raised seating position, a relatively compact turning radius for a full-size chair, and a listed range of up to 18 miles. The trade-off is transport: the current specification table says the chair does not fold or disassemble, and lists a 97 lb base. This is not a lightweight take-apart travel chair, so measure the home and plan vehicle access before ordering.

Understand the Drive Configuration

The P312A product information describes the Dualer as a 2-in-1 drive platform. Its sales text says rear-wheel drive provides a more natural straight-tracking feel, while front-wheel drive responds differently in turns. However, the current structured specification table identifies the listed configuration as rear-wheel drive. Confirm with the seller whether the delivered unit is RWD, whether a drive conversion is available on this order, and what the conversion procedure requires. Do not assume that a single control or setting changes the drivetrain.

Seat Elevation and Rider Fit

The power seat is listed as standard, with seat height from 22 to 27 inches, an 18-inch seat width and 16-inch seat depth. Flip-back armrests are listed, and the legrest configuration includes a footplate with upgradable elevating legrests. Compare the seat dimensions and transfer height with the rider's needs, and confirm the selected joystick position and leg support. Seat elevation changes the rider's position; use it according to the owner's manual and consider room clearance and the complete chair configuration at its raised height.

Space, Surfaces and Performance

The seller's current specifications list an overall size of 24 inches wide by 38 inches long, a 21-inch turning radius and 2 inches of ground clearance. Measure doorways, tight turns, tables and the approach to the intended charging and storage areas. The 12-degree maximum incline rating is a published limit, not a recommendation to attempt every slope; surface, traction, rider load and approach all matter. Foam-filled drive tires and solid casters avoid routine air-pressure checks, but do not remove the need to follow the manual's surface and obstacle guidance.

Published performance is up to 5 mph and up to 18 miles per charge, with a 300 lb maximum capacity. Treat speed and range as test-based figures, not guaranteed trip results. Rider weight, terrain, stops, battery age, temperature and driving style affect usable range. Plan outings with reserve rather than treating the maximum range as a round-trip promise.

Batteries and Charging

The listing specifies two included 12V U1 batteries and an off-board charger. Follow the manual for charging, storage and battery service, and confirm the replacement battery type if service becomes necessary. Do not assume that a different battery chemistry or charger is compatible simply because the voltage appears similar.

Transport and Order Checks

The current specification table lists a 97 lb base, a 52 lb battery pack and a 40 lb standard seat; it also marks the chair as neither folding nor disassemblable. The listed 189 lb overall weight reflects those components together. Plan loading equipment and vehicle capacity around the complete chair, and verify how the batteries and seat are handled for transport with the dealer. Before purchase, confirm drivetrain, joystick selection, legrest, seat fit, charging setup and the vehicle or doorway measurements against the exact configuration being supplied.
