...and I think it's a bit crap. Inflatable chair.

I think I'd have to make a back frame thing for it and bolt it to the bench to be actually useful. Oh well, maybe I'll take it back.
I think someone on here mentioned inflatable chair, and that's what got me thinking about it.
Here's my Trustpilot review:
Product doesn't exactly do what it says, namely providing "a comfortable and secure seating experience". If you've got something to lean back against, then yeah, but the product implies that you can sit by relying on the straps alone. This means having to set them so the chair back is at an acute angle to the bottom, otherwise there's not enough tension on the back support to stay upright. It sort of works, but you can't really relax. Even with something to lean back against and thus more stable, the tubes aren't large enough to take enough weight without bottoming out, really. Finally, the so-called built-in pump, I can't figure out how it works (hopeless instructions), and would be absurd anyway, much easier to just blow it up with your mouth. Overall, not a great product for £15. I bought this for sitting on the metal bench in my small inflatable boat while I'm sea fishing, and I am not confident at all it will be fit for purpose without I make a chair frame for it, which sort of defeats the object.
