Maxim Mattress is a California factory-direct brand that has handcrafted mattresses since 1979. The lineup centers on The Windsor, a 13-inch 996-coil super-plush hybrid from $1,299. It also includes the D-76 Dunhill orthopedic extra-firm and the Newport Cooling foam bed. These are heavy, non-boxed builds with CertiPUR-US foams, sold online and through select dealers. You'll want to ask for trial and return terms in writing, because the brand doesn't publish them.

The Windsor 13in Super-Plush Hybrid, product photo
Choose Maxim if you want a heavy, hand-built, non-bed-in-box mattress made in Los Angeles since 1979 with firm orthopedic or plush hybrid options. Best for back/stomach sleepers wanting extra-firm support (D-76 Dunhill), side sleepers wanting super-plush pressure relief (Windsor), and foam fans wanting cooling (Newport). Not ideal if you need a compressible bed-in-box, powered/adjustable-base compatibility, a stated sleep trial, or a budget price.

Chapter 02
Comfort and firmness: which mattress fits you
Why this matters to you: Feel names are the brand's words, not measurements. Use them to shortlist two or three beds, then let your body decide.
Side sleepers wanting super-plush pressure relief: start with The Windsor hybrid.
Back/stomach sleepers or those advised to sleep very firm: start with D-76 Dunhill Orthopedic extra-firm.
Hot-sleeping foam fans: consider Newport Cooling in Plush for softer contour or Medium-Firm for easier movement.
Shoppers wanting boxed delivery: ask about Glacier Silk v4/v5 boxed option, since Windsor/Dunhill are sold as traditional non-boxed builds.
Adjustable-base users: confirm compatibility before buying, as Windsor/Dunhill pages flag rigid steel edge/no powered-base pairing.
Sizes Twin through Eastern King/Cal King are listed across the core models.

Which Maxim Mattress feel fits you?
Weight chart not yet researched
Weight and sleep position can change how a bed feels. We have not yet checked whether Maxim Mattress publishes a fit chart by body weight, so use a trial, where one is offered, to test the bed the way you sleep at home.
Neck: on your side, your nose should line up with the middle of your chest, not tip up or down.
Shoulders: your bottom shoulder should sink in. Tingling or a numb arm means the bed is too firm for you.
Lower back: on your back, slide a flat hand under your waist. A big gap means too firm; no room at all can mean too soft.
Hips: ask someone to look from the side. Hips lower than shoulders means the bed is too soft for you.
Figure 2.1: Four checks to run in a store, lying still in the position you sleep in most. The store test in chapter 11 says how long to lie on each bed.

How well do the mattresses hold up?
Why this matters to you: A mattress is a long buy. Lean on the written warranty and real owner reports to judge how it will last.
Brand emphasizes dense, hand-built construction, steel-perimeter/foam-encased edges, HD SmartFoam, and stabilizing base foam for slat frames; Windsor weights listed approx. Twin 70 lbs, Full 80 lbs, Queen 95 lbs, King 130 lbs, indicating heavy builds. Standard cover is 10 Year Platinum Warranty with Forever Warranty+ available/upgradeable on select mattresses.
Independent long-term sagging, edge-breakdown, or foam-softening test data Not published as of Sept 2026. Rigid steel-edge builds (Windsor/Dunhill) cannot be compressed for parcel shipment or paired with powered bases, which limits flexing but requires traditional handling.

What do the warranties cover?

Optional: Forever Warranty+ Available; homepage frames lifetime promise as We will warranty your mattress for life, Limited, Available On Select Mattresses, with online-only lifetime on certain styles and shops offering their own extended plans; Q+A notes select dealers allow buying/upgrading to Forever coverage within 14 days of original purchase.

Maxim Mattress vs. other mattress brands
Why this matters to you: A fair comparison needs the same facts for both beds. Line up price, trial and warranty for each one.
Versus mass bed-in-box hybrids (Casper, Purple, Nectar): Maxim is heavier, hand-built, non-compressed with steel-edge support and factory-direct heritage, but lacks a clearly stated trial/returns policy on its site. Versus heritage innerspring/orthopedic makers: D-76 targets extra-firm chiropractor-recommended support with 1000+ coils and HD/charcoal foams.
Versus cooling-foam specialists: Newport leans on Arctic Breeze fabric plus PermaCold gel foam rather than phase-change covers. Shop on build feel (plush Windsor vs ultra-firm D-76 vs foam Newport), boxed vs white-glove needs, and written trial/warranty terms.
Competitor details reflect published prices and specs on the date shown. Mattress brands may update prices and trial terms over time.
