King Pocket Coil Springwall® H2 Chiropractic® Adjustable Base Compatible 14 Inches All Mattresses
King mattresses measure 76" × 80" — the widest standard size, giving each partner the same personal space as a twin. They're the top choice for couples who want maximum room, families who co-sleep, and larger master bedrooms. Compare every king option below by brand, feel, and price.
Pocket coil mattresses use individually wrapped coils that move independently, delivering targeted support and far less motion transfer than traditional innersprings. They contour better and isolate movement while keeping a coil bed's breathability — a great fit for couples. Compare every pocket coil option below.
Springwall H2 Chiropractic mattresses represent the pinnacle of luxury and support in the Springwall lineup, handcrafted in Canada with premium hybrid technology for an ultra-comfortable, chiropractor-approved sleep experience. Springwall Chiropractic® and the Canadian Memorial Chiropractic College (CMCC) have joined forces to improve the sleep of Canadians with a long-term funding agreement to aid the Research & Development with the purpose of maintaining and improving health through better sleep.
These mattresses are built to flex with adjustable bed bases — bending smoothly at the head and foot without damage — so you can raise, recline, and find your ideal position. Compare every adjustable-base-compatible option below by brand, type, and feel.
