Having slept on water beds for over 50 years, and tired of patching leaking bed blatters, and also being partically crippled due to botched dual knee replacemtns, I tried the air mattress of a friend. It was made by a leading manufacturer of camping equipment, but also sold air mattresses. So I ordered on from the same company. Within a few days, it developed a leak. Based on the specifications and warranty of the Serta, I ordered their product. Thus far, it has performed quite well, their "constant air pressure" system is great, and I got a night's sleep without pain, or worrying about leaks!
