At three times the cheap air mattress at Wal Mart I expect this to be 3 times better. Instead it's 3 times worse. The coleman has an old school valve, the wal mart brand has a two way valve so you can open it up and air it up without worry of losing air. For me the Wal Mart brand is still going strong, the coleman has already sprung a leak and has to be aired up every 2 hours. Save your money and just buy the Wal Mart brand.
