Never buy again

We bought a sleep number bed 4 years ago. The first couple of months it was great. After about 6 month we could no longer sleep on it. Both husband and I would wake up in so much pain from either pur back, hips or shoulders. We had to purchase a new bed because we could not get a good night rest. Shipping and setting it up is the best part of it since it was so easy to unbox and put together.
