Lumbar Support Cushion

A lumbar cushion contoured to fill the gap between the lower back and a flat chair back. The shape is the product: it is built up through the side panels and relieved down the centre so support lands either side of the spine rather than pressing directly on it, and it tapers at the top and bottom so it does not push you forward out of the seat.

The core is moulded memory foam that conforms at the surface under body heat but keeps its contour through a full working day instead of flattening out by the afternoon. The cover is a black breathable three-dimensional mesh on the contact face, which moves air behind your back — the difference between a cushion you use in summer and one you take off by eleven.

Two adjustable straps, an upper and a lower, hold it in position. Two rather than one is what stops the cushion riding up the seat back as you shift. It fits an office chair, a car seat, a dining chair or a recliner. Position it so the fullest part sits in the curve of your lower back. The cover unzips and machine washes; do not wash the foam.
