Title: It's ok, you get what you pay for.
Review: This was pretty cheap, so not too surprisingly for the price it's ok but no more than that. It's certainly firm and doesn't let any air out. The air lock on it is quite clever actually and very secure. The two problems it has are that the ridges are noticeable so it's not that flat. I put a thick blanket on it then it was fine, but I only realized this after one night. The other problem is that if the bottom is on a hard surface it squeaks a lot as soon as you move an inch. I then put my rug underneath it and that was fine. These fixes might not be available in a tent though. I'd probably spend a bit more next time, I only needed it for a week though and it did the job.
