Overview
Tempur-Pedic makes this topper from its own memory foam and covers it in a breathable, cool-to-the-touch fabric. Corner straps hold it on the mattress.
The foam is meant to absorb pressure points and reduce motion transfer from a partner. A washable cover makes upkeep easier. Firmness is listed as medium firm in the specs and medium in the title, so the exact feel is unclear.
Who it's for
Couples on a King bed who want less motion from a partner and a softer surface. Those after a spill barrier should add a separate protector.
Pros and cons
- Reduces motion transfer
- Corner straps hold it in place
- Not water resistant
- Firmness wording differs
- Foam washing not covered
- Warranty limited to original buyers
Performance notes
Memory foam gives under body weight and spreads pressure, and it recovers slowly as the body moves. Corner straps stop the topper sliding. A cooling cover reduces heat buildup, but memory foam still retains some warmth.
