Very pleased with this mattress. Inflates in about 3 minutes with built in pump that plugs into an electrical outlet and is operated with the flip of a switch..so easy. I laid on it a while and was comfortable, then my teenage daughter had a sleepover and 2 girls used it and were very comfy all night!  The 22 inch height makes it easy to get in and out of. To me that is a big plus. I received this through TryItin exchange for my thoughts. .
