Is the Seafield good for side sleepers?

Sealy lists it for side sleepers, and the medium tight top gives some cushioning at the shoulder and hip. Heavier side sleepers may find it firmer than expected and should try it in a store first.

How does it compare with the Posturepedic hybrid models?

The Seafield is a traditional innerspring with gel foam on top, so it has more bounce and motion transfer than Sealy's hybrid lines. Hybrids add more foam and pocketed coils for pressure relief, usually at a higher price.

Does it work with an adjustable base?

Yes, the mattress is listed as adjustable-base compatible. The standard box spring in the set is not meant to flex, so use the mattress alone on an adjustable frame.

What comes in the set?

The set includes the 13-inch mattress and a standard-profile box spring. The mattress-only option ships without a foundation, so you need a frame or base.

What size is the California King?

The Cal King measures 83 inches long by 76 inches wide, so it is longer and narrower than a standard King. Measure your room and frame before ordering.

When is the best time to buy it?

Mattress prices at department stores drop around major holiday sales and Presidents' Day. The set was $1,099 at Macy's as of November 3; check whether a sale or coupon beats that.
