Leon 1.1 is an indoor/outdoor rear-wheel drive power wheelchair that offers extra stability when driving over uneven terrain and climbing obstacles. Leon features Karma’s Versus seating system, which is compatible with most after-market backrests, positioning supports, and cushions to create the perfect fit for any user.
Seating System
Karma designed its Sling seat for users with low-to-medium clinical needs. The adjustable seat frame and optional power positioning functions provide moderate support, while flip-back armrests simplify the transfer process.
The Leon Sling backrest folds down flat for storage and transportation.
