We sold our home and moved into a condo while we wait for our new home. Our Sleep Number is in storage. Our rental has a Sealy 12" Medium Memory foam To Go. It is SO COMFORTABLE. Plus the price was under $500! So we bought one for our new home. The new guest room gets the Sleep Number!. Mike. Nasville. Tue Jan 06 2026
