You can now save up to $300 on a Sonno Mattress through November 20, so if you've been thinking about changing out the one you have, now's the time.

"Unlike other memory foam mattresses, the Sonno immediately adjusts to suit your body position without requiring a "warm up" period, and holds your weight whenever you roll. The result is a feeling of floating, which allows you to rest naturally, isolated from vibrations and movement that interrupt sound sleep."

33% CoolMax, 67% polyester cover; 4.5" polyurethane foam core; 2.75" visco-elastic memory foam layer.

Sonno Prima Queen: Medium or Firm, H 8" W 60" D 80", $1,500 $1,300, Buy it here.
