We should have ordered this years ago. This is the second BB product in our home. We actually look forward to going to bed now because of this new bed. We went with medium and the pillow top which satisfies one person that prefers plush and the other that prefers more firm. Seems to be a good balance for us. Can confirm almost no mattress movement when on person moves in bed. This bed replaced our Sleep Number bed. What an improvement! We have 6 months on this bed and are still telling people about it!
