Need a new bed for my bad back and neck
 

I need to replace my bed. Has anyone bought a bed in the last year that you would highly recommend for those of us with bad backs and necks. I sure would appreciate your input on the type of bed, the cost and why you like it. A good bed can get expensive so, I don't want to mess this purchase up. I've read stories of people buying expensive beds only to have them start sagging six months later. That is disastrous for people with bad backs. Yikes. Help needed! Thanks :)

This is completely out of the box, but Laura's been doing well for about a decade using a wool futon, rotated every day to make sure you don't end up with lumps, on top of a top of the line Thermarest pad on the floor. Not saying that it's for everyone but it's good proof that cost isn't the best determiner of what works.

I recently got a Sleep Number. Works great for me.

I got mine from Sleep Country. They have excellent return policies and were very educational. I went back to the store twice and spent lots of time laying in diff positions on beds. Ended up with a medium firmness, no pillow top. This link to their bed selector might be useful to you even if you don't buy from them...

Tempurpedic, Sleep Number, and Capser...I have a Tempurpedic (firm) my pressure points don't hurt any either.
