The bed originally works for one year after that the mattresses developed, leaks. A replacement air chamber was given free u see warranty but developed another leak a year later but was not considered to be under warranty. Then, the second air chamber developed leaks as well. Since we had spent the money for the bed, I c ouldnt afford to buy another one so we bought 2 air chambers. Now 2 months later they both leak continually, hence we need a new pump I am assuming. I have no more money to dump into this faulty system. I wake up with no air in the chamber every morning, stiff, aching and numb. Do NOT purchase from this company.
