Soft Comfy Seat Cushion with Back Support Elastic Strap Armchair Cushion Cozy Warm Plush Lazy Sofa Office Seat Pad Pillow Relieves Back Coccyx Sciatica Tailbone Pain Relief Chair Cushions Floor Mat

So very nice on my back

This cushion is really good for people suffering with back problems especially base of spine

I thought this might be rather large for my office chair but it's a good fit: it might be too small for an armchair. It's very comfortable and not bulky, and it does not force you into the 'ergonomic' pose that is too upright and often painful for those without a perfectly functioning back.
