A Hemi Height That Actually Helps You Propel
The ProBasics K2 Standard Hemi Wheelchair is built for riders who need real flexibility in seat height and leg positioning. Its steel slide-tube frame, protected by a chip-resistant silver vein powder coat, supports up to 300 lbs over years of daily use.
A dual-axle system drops the seat from a standard 19.5" adult height to a 17.5" hemi height, letting feet rest completely flat on the floor for an efficient, low-strain foot-propulsion stroke β a meaningful difference for shorter users or anyone managing one-sided weakness after a stroke. Multi-position front caster forks keep the seat level and balanced at either height, so lowering the chair never comes at the cost of proper posture.
Key Features
- Dual-Axle Height Adjustment: Shifts between 19.5" standard and 17.5" hemi height for effective foot-push propulsion.
- Multi-Position Front Forks: Adjustable caster brackets keep the seat level and properly aligned at either height.
- Six Sizing Variants: 16", 18", and 20" seat widths, each available with swing-away footrests or elevating legrests.
- Pneumatic Piston Legrests: Elevating variants use a stepless gas piston to find the exact angle for comfort or edema relief, rather than a handful of fixed pin positions.
- Flip-Back Desk Arms: Shortened padding fits flush beneath tables and flips up or detaches for barrier-free side transfers.
- Bacteria-Resistant Vinyl: Non-porous, moisture-resistant seating that sanitizes instantly with standard disinfectants.
- Maintenance-Free Wheels: Flat-free solid urethane rear tires with high-grip composite handrims.
- Precision Sealed Bearings: Protect internal rolling mechanics from dust and moisture for a smooth, low-friction glide with no lubrication required.
Specialist Insight: Many wheelchairs overlook the mechanical relationship between rear axle height and front caster tilt, but the K2's multi-position fork system keeps the seat balanced and level no matter which height you choose. The pneumatic piston legrests on the elevating variants are a genuine quality-of-life upgrade too β caregivers get smooth, steplessly adjustable control instead of the rigid clicks of a traditional pin-lock mechanism.

Frequently Asked Questions
Q: Why does the hemi-height setting matter so much for stroke survivors?
A: Standard wheelchair heights can leave a seated user's feet dangling or only touching the floor with their toes. For those managing one-sided weakness, this makes self-propulsion exhausting and unsafe. Lowering the K2 to 17.5" places the foot completely flat on the floor for a proper, low-strain driving stroke.
Q: What's the advantage of the pneumatic piston legrest?
A: Traditional elevating legrests lock into a few fixed clicking angles, which can miss the exact elevation needed for comfort. The gas piston here lets a caregiver glide the leg panel steplessly to any precise angle instead.
Q: Do the sealed wheel bearings need maintenance?
A: No. Sealed bearings keep out hair, dust, and debris that can cause squeaking or drag in open-ring bearings, giving a smooth roll over carpet and sidewalks without any lubrication needed.
