Marquis Mattress is a Dallas-area bed-in-a-box maker. It sells four cooling-focused models: Cool X, UltraREST, CopperZen and CopperZen Reserve. Prices run from about $268 to $1,215, with a 10-year warranty headline. It's best if you want budget cooling foam or a plush copper hybrid. The catch is that it doesn't publish a trial, return terms or full warranty terms (checked September 2026).

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: CopperZen or CopperZen Reserve in ultra-plush (scale 3) for shoulder and hip cushioning; Cool X in Plush is the budget alternative. Back sleepers: Cool X or UltraREST in Medium Firm (about 4) for flatter support; Reserve only if you like a soft top over zoned coils. Stomach sleepers: Medium Firm options only, and confirm you do not sink, as exact ILDs and densities are Not published as of Sept 2026.
Combination sleepers and couples: UltraREST or CopperZen hybrids for coil bounce plus motion isolation. Heavier builds: hybrids over all-foam for coil support, and confirm edge feel, as coil counts and weight limits are Not published as of Sept 2026. Hot sleepers: cool-touch covers with gel, copper or graphite are the pitch, but independent cooling test data is Not published as of Sept 2026.

Which Marquis 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 Marquis 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.

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.
A 10-year warranty is stated on the Cool X page and warranty registration and support links appear sitewide, but sag-depth thresholds, covered-defect definitions, foundation rules, and claim steps are Not published as of Sept 2026. Durability signals are brand-reported only: CertiPUR-US foams, zoned coils with reinforced edges (UltraREST), and USA assembly.
Long-term owner durability data and independent wear testing are Not published as of Sept 2026. Heavier shoppers should confirm support limits before buying.

Delivery, setup and old-mattress removal
Why this matters to you: Delivery terms decide your first week with the bed. Confirm the date, setup and old-bed removal before you pay.
Mattresses ship compressed in a box; setup is unbox, unroll and expand, and all lines claim adjustable-base compatibility. Shipping cost, coverage area, delivery timeframes, white-glove setup, and old-mattress removal pricing are Not published as of Sept 2026; cart pages note shipping and taxes recalculate at checkout.

What do the warranties cover?
Why this matters to you: A warranty is only as good as its terms. Read the written terms and use a supported base, because the wrong frame can end coverage.
A 10-year warranty is stated for Cool X, and footer links offer warranty registration and warranty support, but full terms are Not published as of Sept 2026, including covered defects, sag-depth minimums, exclusions (stains, misuse, commercial use, foundation violations), transferability, prorating, and claim process and costs. Get the warranty document by email before buying.

Strip the bed down to the mattress and wait a few hours so the top layers can recover.
Lay a straight edge (a broom handle or long level) across the dip, resting on the flat parts.

Why this matters to you: Star ratings depend on who posts and where. Read the low-star reviews for patterns, not just the average.
Aggregated star ratings, review counts, and complaint rates on the brand site, Google, BBB, or independent outlets are Not published as of Sept 2026. No third-party scores for cooling, motion isolation, edge support, or durability were found as of Sept 2026, and no Amazon, Wayfair, or big-box listing with ratings was verified.
Shopper tip: use phone (214) 838-1538 or info@marquismattress.com to request verified owner feedback and firmness guidance, since published proof is thin.

What are the mattresses made of?
Why this matters to you: Layer names say little without numbers. Ask what is inside your exact model, layer by layer.
Comfort layers per official pages: cool-touch covers (copper-infused on CopperZen lines); cooling-gel memory foam (Cool X, UltraREST); copper-infused memory foam, graphite-infused foam and two gel strata (CopperZen, Reserve). Support: ventilated support foam base (Cool X all-foam); individually encased pocket coils, 3-zone on UltraREST and tri-zone glue-free on Reserve.
Claims: CertiPUR-US certified foams across lines; fiberglass-free stated on UltraREST, CopperZen and Reserve; made in USA and mattress-in-a-box format stated. Not published as of Sept 2026: foam densities, ILDs, layer thicknesses beyond Cool X 14 inch and UltraREST 11 inch naming, coil counts and gauges, cover fabric content, and fire-barrier details.

Marquis 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 Zinus, Lucid and other budget cooling-gel beds: Marquis Cool X prices in the same value band with a USA-made pitch, but rivals often publish trial and return terms Marquis does not. Versus Allswell, Dreamfoam and budget hybrids: UltraREST matches on pocket-coil plus gel-foam basics while trailing on published specs and trial transparency.
Versus copper lines like Brooklyn Bedding CopperFlex or Bear Elite Hybrid: CopperZen and Reserve share the copper-for-cooling story at lower list prices, but publish less construction proof and no verified trial. VersusTempur-Pedic and Sealy chill lines: Marquis is far cheaper with no equivalent testing, store footprint, or warranty documentation.
Competitor details reflect published prices and specs on the date shown. Mattress brands may update prices and trial terms over time.
