The wedge adapts a horizontal seat to a 10 degree plus angle: this gently rocks the pelvis forward on the hips, taking the strain off the lower back. Upholstered in the new grip-right velour material which prevents slipping. The wedge has the added benefit of the contoured centre which is recessed to reduce pressure on the coccyx. It is light and has a carrying handle. Dimensions 40cm x 37.5cm x 14cm (16" x 14.75"x 5.5") Price £43.78 + VAT. Delivery. Colour options: Blue,Green, Grey or Black.
