Our take on the Sealy Posturepedic Seafield 13" Tight Top Mattress Set

The Sealy Posturepedic Seafield is a 13-inch medium-firm tight-top innerspring mattress built around Sealy's Posturepedic Support System with PrecisionFit encased coils and a reinforced Coil Edge. It adds a gel foam layer, a MoistureProtect cover and Surface-Guard allergen protection, and it works with an adjustable base. The set version pairs the mattress with a standard-profile box spring; the mattress-only version ships without a foundation. Its only recorded daily price is $537.30, so there is no recent range to compare against yet.

Best forSide and combination sleepers who want medium supportShoppers replacing a sagging innerspring on a budgetAllergy-sensitive sleepers who want surface allergen protectionBuyers who plan to use an adjustable base
Pros
  • Medium tight-top feel suits side and back sleepers
  • Encased PrecisionFit coils give targeted support with less motion transfer than a traditional spring unit
  • Reinforced Coil Edge holds up along the sides
  • MoistureProtect cover and Surface-Guard allergen barrier
  • Adjustable-base compatible
  • CertiPUR-US certified low-VOC foam
Cons
  • Innerspring core still transfers more motion than all-foam or hybrid designs
  • 13 inches is bulky and needs deep-pocket sheets
  • No foundation in the mattress-only option
  • Firmness is fixed; no comfort exchange built into the spec
  • Only 35 ratings, so the review base is thin

Pros

  • Good value for a mattress-and-box-spring set

Questions and answers

Is the Seafield worth it?
At $537.30 at Macy's as of October 28, 2026, it is a low entry price for a Sealy Posturepedic innerspring set with encased coils and a reinforced edge. It makes sense if you want medium support and an adjustable-base-ready mattress without paying hybrid prices.
How does it compare with a hybrid or all-foam mattress?
The Seafield is a true innerspring with a gel foam layer on top, so it sleeps cooler and feels bouncier than all-foam. It transfers more motion than a pocketed-coil hybrid with a thick foam base, but it costs far less.
Does it work with an adjustable base?
Yes. Sealy lists the Seafield as adjustable-base compatible, so it can be used on a power base. The set's standard-profile box spring is not an adjustable base.
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 supply your own base or box spring.
What size is the California King?
The Cal King measures 83 inches long by 76 inches wide, which is longer and narrower than a standard King. Check your room and frame before ordering.
When is it cheapest?
The only recorded daily price is $537.30 on October 28, 2026, so there is no history yet to show a low point. Mattress prices usually drop around major holiday sales, so watch for those windows.
