Overview
A 3-inch memory foam topper sized 79 by 75 inches for a king mattress, built to soften a too-firm mattress and ease pressure at the hips and shoulders. Tempur-Pedic markets it as a medium-firm cooling layer with a washable cover.
That framing matters because it is a comfort layer riding on top of an existing mattress, not a mattress replacement, and its effect depends heavily on how firm that base mattress already is.
- 3-inch memory foam, sized for a king mattress
- Marketed as a cooling, medium-firm layer
- Washable cover
- Meant to sit over an existing mattress, not replace it
Who it's for
Side sleepers and anyone with hip or shoulder pain on a mattress that is firmer than they would like, especially owners of firm hybrid or innerspring beds. Not the right buy for someone whose mattress is already soft, or who wants a thicker topper than 3 inches.
Pros and cons
- Corner straps criticized as an awkward attachment method
- One buyer denied a warranty claim over normal-wear stains
- Some call the price high relative to the improvement
Performance notes
Several describe it settling in fully only after the topper has had a day to expand once unpacked. It stays attached with corner straps, which more than one reviewer found workable but not elegant.
