I don't know how we've managed without these for so long. We visit a lot of UK beaches and have always sat directly on the sand. Well, not any more! These are easy to fold and are genuinely really comfortable to sit on. Being able to carry them on your back means you have hands free to carry other things, hold a dog's lead etc. You do need to make sure you have the back straps level, or you will find you get clonked in the head by a corner of the chair! It's great that they are height adjustable too, it's possible to lie nearly horizontal without getting sand all over you. The side pockets are really handy, space for drink bottles, sun lotion etc. Having a zip pocket is also good for storing phones in. Absolutely no complaints about these chairs, I just wish I'd found them sooner.
