We've had ours for four years and love it. I have troubles sleeping on other beds. However, if you are a cuddler, somone who needs to nuzzle up to someone else, this bed probably isn't for you. The bed is divided into two adjustable air chambers. When I roll over to my wife's side of the bed, it feels like I'm rolling off a cliff because her side is much softer than mine. So if you like to cuddle, you'll probably find this bed annoying. Luckily for us that's not the case.
Other pro's - adjustable. this option comes in handy if you have a sore back and want something a little stiffer. When my wife was pregnant and ger weight constantly changing, she could adjust the bed to suit her needs. It has a twenty year warranty. The pump holds the air in if it loses power or gets unplugged.
The pump can be very noisy, although they have a quiet model. But when you think about it, does it really matter how noisy it is? You'll be adjusting the bed when your awake anyway. It's expensive but well worth the cost. If I ever get another bed, it will be a King Size select comfort.
