Our take on the Beautyrest BRS900 King Mattress

The Beautyrest BRS900 is a 12-inch king mattress that pairs pocketed coil springs with a layer of memory foam on top. It is built at an extra-firm comfort level, so it suits sleepers who want a flat, supportive surface with little sink-in. Against softer hybrid rivals, it trades cushioning for back support and a bouncier feel from the coils. Owners of firm mattresses in this class often note strong edge support and easy movement, but heavier side sleepers may find it too hard.

Questions and answers

Is the BRS900 good for side sleepers?
Mostly no. At extra firm with a thin foam layer, it gives little give at the shoulder and hip, so side sleepers often feel pressure. Back and stomach sleepers are the better fit.
Does it need a box spring?
It works on a box spring, a slatted frame or an adjustable base. A solid, supportive foundation keeps the coil unit from sagging.
How firm is extra firm here?
It is at the hard end of the scale, with minimal sink-in. If you are used to medium mattresses, expect a noticeably stiffer surface.
Will two people feel each other move?
Less than on a plain foam bed. The pocket coils are individually wrapped, which limits motion transfer between partners.
What is the 12-inch height good for?
It fits standard king sheets and gives a taller profile that is easier to get out of. Deep-pocket sheets are the safe choice.
Where is the Beautyrest BRS900 King Mattress cheapest?
At The Home Depot, for $610.00, 24% under what the other stores charge, as of our latest check.
