This air mattress was a good value. Just a basic air mattress to have for overflow guests. The built-in pump was very easy to operate and worked well. The mattress was filled in about a minute. I left it pumped up for several days so it could stretch as needed due to its newness. After a couple of supplementary fills, it has been stable and ready for our guests. Could it be more comfortable? Sure, but for the price this fits the bill.
