Every other blanket has the same flaw outside – nothing is holding it to the chair. The moment you stand up or lean forward, it falls away and your warm setup is gone.
The Chair Blanket's stretch-to-fit back loops over your chair and grips the frame like a fitted sheet grips a mattress. It works on Adirondacks, camping chairs, stadium seats and most other outdoor chairs. Stand up, sit back down – it's still exactly where you left it.
The Chair Blanket is the first outdoor blanket that was actually built to stay on a chair.
