You never seem to have an inflatable bed when you need one. Then you buy one and the piece of crap leaks or is really uncomfortable. This one works well. A typical two-prong power outlet nearby lets you fill the Insta Bed quickly with the mattress’s built-in air pump — and this is key — it quietly keeps it inflated to your desired pressure all night. You also deflate it via that pump. Folds into a small twin pillow-sized bundle for storage. It is firm enough to fool me, doesn’t lose air very fast either. Guests have commented on its comfort. Returning guests pick the room with that mattress over a guest room with a real queen-sized bed for some reason.
