Skanto | Pustende Gelé PutemousseMost chair cushions do a mediocre job of supporting your back. But they're often bulky, get too hot, and have a hole cut out to make room for your tailbone. The Ventilated Gel Cushion supports your back so well you could sit on an egg without breaking it! Sit on the hardest surface and still feel comfortable. Ventilated Gel Cushion features a honeycomb design made from an ultra flexible polymer that stays cool to the touch, allowing air to circulate.
