- Which firmness should I pick?
- Side sleepers usually do best on the plush or soft. Back and stomach sleepers and heavier buyers should take the extra firm. Couples with different preferences often settle on the plush.
- Does it work on an adjustable base?
- Yes. Pocketed coil mattresses bend, so the BRS900 works on an adjustable base as well as a box spring or slatted frame.
- How does it compare with an all-foam mattress?
- It feels springier and sleeps cooler, and it isolates motion well for a coil bed. All-foam beds still beat it on edge support and on quietness.
- Will a king fit my bed frame?
- It is a standard king at 76 by 80 inches, so it fits any king frame or platform. Check that your foundation can carry the weight of a 12.25-inch coil mattress.
- Does it need a box spring?
- No. A slatted platform or adjustable base is enough. If you use a box spring, pick a sturdy one, since the mattress is heavy.
- How long should it last?
- Expect roughly seven to ten years for average-weight sleepers. Heavier sleepers and the soft version tend to show wear sooner.
