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

Beautyrest Silver is an elevated sleep experience that gives you pure sleeping satisfaction so you can reach your best every day.

This mattress is just right. It was a great purchase and the price was fair. It’s firm yet not hard as a rock. It has a little fluff to it and seems to be just the right mix. Another plus is it doesn’t put out heat. I recommend this mattress.. Kimberly. Cypress, TX. Thu Feb 13 2020
