Maxim Mattress Review

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.

If you sleep on your side and want super-plush pressure relief, start with The Windsor hybrid. If you sleep on your back or stomach, or you've been told to sleep very firm, start with the D-76 Dunhill Orthopedic extra-firm. If you sleep hot and like foam, try the Newport Cooling in Plush for a softer contour or Medium-Firm for easier movement.

If you want boxed delivery, ask about the Glacier Silk v4 or v5 boxed option. The Windsor and Dunhill are sold as traditional non-boxed builds. If you use an adjustable base, confirm compatibility first, because the Windsor and Dunhill pages flag a rigid steel edge and no powered-base pairing. Sizes run from Twin through Eastern King and Cal King across the core models.

The Windsor starts at $1,299, and so does the Dunhill Orthopedic (D-76). The Newport Cooling, Glacier Silk and Glacier Silk Pro start at $1,399. These come from the brand's product pages. The brand advertises $500 savings for first responders, military, police and teachers with verification. The homepage also notes discounts for older adults and learners.

You're paying for factory-direct, hand-built construction, 1000-coil-class support, domestic CertiPUR-US foams and a pledge to never use fiberglass. The brand does not publish the final delivered price with white-glove options, taxes or the Forever Warranty+ upgrade cost (checked September 2026).

The Windsor has a soft plant-based cotton top quilted to supportive foam, ventilated plush rubber-tree foam and HD SmartFoam layers. Under that are independent pocketed steel coils (about 996) with a steel perimeter, foam edge framing and stabilizing base foam. All foams and gels are stated CertiPUR-US certified. It's assembled in the USA with American and imported components, and the brand states it will never use fiberglass.

The D-76 Dunhill has a breathable faux-suede cover. Under it sit 1 in of quilted firm SmartFoam HD and 1 in of SmartFoam HD. Next come 2 in of charcoal foam and a 2 in transition layer. The charcoal foam is noted for rest, recovery and antibacterial qualities. Below that are OrthoCoils+ 1000+ wrapped coils. They have a steel perimeter and foam-encased edge. A 1 in layer of stabilizing base foam sits at the bottom. The Newport has an Arctic Breeze Fabric 3 cover and PermaCold gel-infused memory foam. The brand does not publish full chemical, latex or organic cotton certification documents beyond its CertiPUR-US claim (checked September 2026).

The brand emphasizes dense, hand-built construction, steel-perimeter and foam-encased edges, HD SmartFoam and stabilizing base foam for slat frames. These are heavy builds. Windsor weights run about 70 lb for a Twin and 80 lb for a Full. A Queen is 95 lb and a King is 130 lb. The standard cover is a 10 Year Platinum Warranty, with Forever Warranty+ available on select mattresses.

The brand doesn't publish independent long-term data on sagging, edge breakdown or foam softening (checked September 2026). The rigid steel-edge builds (Windsor and Dunhill) can't be compressed for parcel shipment or paired with powered bases. That limits flexing but means traditional handling.

The brand's site shows a store rating of 4.96 from 429 reviews. The Windsor is about 4.6/5 from 223-plus ratings (224 reviews). The Dunhill is 4.90/5 from 20 ratings (21 reviews). The Glacier Silk Pro is 5.00/5 from 18 ratings (19 reviews). Visible comments praise the plush feel, cooling, back support, and helpful staff and delivery confirmation calls.

The brand does not publish independent third-party review volume or BBB complaint details (checked September 2026). We couldn't confirm a recurring defect pattern from the brand's pages alone.

You can buy direct at maximmattress.com, which has product pages for The Windsor, D-76 Orthopedic, Newport Cooling, Glacier Silk and Glacier Silk Pro. The phone is (888) 727-1759. The brand says it sells direct and through select authorized dealers, with retailers noted in California, Arizona, Texas and Nevada.

The brand does not publish try-in-store addresses, a dealer list or online checkout and shipping-zone details (checked September 2026). Call or use Contact Us to find your nearest showroom.

The homepage advertises Free Shipping and White Glove Delivery, with complimentary white-glove or standard delivery on chosen styles. Deluxe styles arrive fully expanded, not compressed, because of the dense build. Reviews mention scheduled home delivery with confirmation calls.

The Windsor can't be compressed for parcel shipment or paired with powered bases because of its rigid steel edge. The D-76 is sold as a Real Mattress, not rolled into a box. The Glacier Silk v4 and v5 are available traditional or in a box. The brand does not publish delivery timeframes, fees by ZIP, setup steps or old-mattress removal terms (checked September 2026).

The brand does not publish a sleep-trial night count, return window, exchange process or restocking and return-fee schedule (checked September 2026). Before you buy, confirm in writing whether trial and returns are offered online or only through select dealers. Ask who pays return freight, and whether Forever Warranty+ affects returns.

The standard coverage is a 10 Year Platinum Warranty, stated on the Windsor and D-76 pages. Forever Warranty+ is an optional upgrade. The homepage frames it as a promise to warranty your mattress for life, limited and available on select mattresses. Some styles get online-only lifetime coverage, and some shops offer their own extended plans. The Q+A says select dealers allow you to buy or upgrade to Forever coverage within 14 days of the original purchase.

To register, send a photo of your mattress and receipt plus your email or phone, by digital or mail-in sheet. You'll get claim instructions and a Warranty Registration Number. Valid proof of purchase is required, and you can call (888) 727-1759. The brand does not cover any transportation costs for warranty service. It doesn't publish the sag-depth threshold, covered defects or exclusions, so request the full warranty document.

Against bed-in-a-box hybrids such as Casper, Purple and Nectar, Maxim is heavier and hand-built. It isn't compressed, and it has steel-edge support. It lacks a clearly stated trial or returns policy. The D-76 targets chiropractor-suggested extra-firm support with 1000+ coils and HD and charcoal foams. Against cooling-foam specialists, the Newport leans on Arctic Breeze fabric plus PermaCold gel foam, not phase-change covers.

Shop on build feel (plush Windsor, ultra-firm D-76 or foam Newport). Weigh boxed versus white-glove delivery and get the trial and warranty terms in writing.
