I am 4'11" and 120 lbs., but my Hubby is 6'1" and 185 lbs. This caused some issues on any mattress!! We bought our Sleep Number(then called Select Comfort) 18 years ago. The only change has been to get new motor and the company is great in response time and service. Would not change my bed for anything! Ours is pillow top and dual controls that deep pocket regular sheet sets fit just fine.
