We just got our second one this summer. Our original one we took to our cottage at the lake and got a newer one for home.
We got the super deluxe one this time. It is a split king size. You can raise the head up (good for my breathing problems) and also raise up the foot (good for hubby's hurting, tired legs). Each side works independantly for that sleepers comfort. It also has a massaging vibration for either the top half of your body, or the bottom half of your body, or whole body. It is so great!

We just love the sleep number bed and have a difficult time sleeping when we go to a motel or someone else's house to sleep over.

I think you will just love the bed. Give it a chance.
We took it apart one summer when we painted the room and couldn't get it together again! Called the 800 number and the lady was so helpful. This time when we moved the older one to the cottage we took digital pictures as we took it apart--it went together like a dream.

Find a store and you can try all the different models. They even have a dog bed!
