Qube Sleep is the BedMart house-brand mattress line. You'll find it only in BedMart's 40-plus Oregon, Washington and Hawaii stores and at shopbedmart.com. Seven gel-cube models (CoreQUBE, Immerse, Intrigue, Indulge and three INTELLIQUBE hybrids) run roughly $2,599 to $13,398. They come with a 365-night exchange-only guarantee and a 20-year non-prorated manufacturer warranty. It's best if you want to test a cooling-gel bed in a store. You won't get a shipped home trial or third-party reviews.

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: start with Distinction INTELLIQUBE (medium-soft graphic) or CoreQUBE and Indulge (medium graphics) for pressure relief at shoulders and hips. Back sleepers: test Intrigue and Elite INTELLIQUBE (extra-firm graphics) plus Immerse for alignment-first support. Stomach sleepers: ask staff for the firmest build since only Intrigue and Elite carry explicit extra-firm graphics.
Combination sleepers and couples: favor the coil hybrids (Intrigue, Immerse, all three INTELLIQUBE) for movement ease and the gel-cube motion-isolation claim. Heavier builds: lean to the five-zone 948-coil INTELLIQUBE flagships with foam-encased edges. Hot sleepers: the whole line is pitched at cooling, with the Kikoo graphite-band flagships making the strongest claims.
All guidance is brand-reported; independent firmness or pressure-mapping data is Not published as of Sept 2026.

Which Qube Sleep feel fits you?
Weight chart not yet researched
Weight and sleep position can change how a bed feels. We have not yet checked whether Qube Sleep 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.

Compare the mattresses
Why this matters to you: Models from one brand can differ in feel, height and layers. Match the feel label and height to how you sleep before you compare prices.

Mattress prices and value
Why this matters to you: A starting price can rise with size, base and delivery. Get the full price for your size in writing before you choose.
Full-line range runs about $2,599 (CoreQUBE XL Twin, North West) to $13,398 (Distinction Split King or Split Cal King, Hawaii). Queen street prices in the North West zone run $2,999 CoreQUBE, $4,199 each for Immerse, Intrigue and Indulge, $5,499 Elite INTELLIQUBE, $5,999 Signature INTELLIQUBE and $6,499 Distinction INTELLIQUBE; Hawaii-zone Queens run $700 higher on most models.
Value read: premium regional-house-brand pricing far above DTC gel and hybrid rivals, justified by BedMart only through 1,116-cube gel construction, Talalay latex and zoned-coil flagships, 365-night exchange rights and a 20-year non-prorated warranty; weak on verifiable value because foam certifications, coil counts below the flagships and independent test data are Not published as of Sept 2026.

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.
Durability evidence is brand-reported only: 20-year non-prorated manufacturer warranty on all models, high-density base foams, tempered-steel coil units, foam-encased edges and five-zone construction on flagships. Independent durability lab results, sag-depth statistics, body-impression rates, edge-breakdown or coil-fatigue data are Not published as of Sept 2026.
BedMart's warranty FAQ notes coverage generally targets measurable defects and body impressions over 1.5 in on quilted tops and 0.75 in on memory foam, not gradual comfort loss. Practical tips: use a proper supportive foundation or adjustable base, keep the law tag and receipts, use a waterproof protector since stains void exchange and warranty rights, and rotate only if the model is designated flippable.

Sleep trials, returns, exchanges and fees
Why this matters to you: Feel is hard to judge in a store or in a week. Know your exit plan and its cost before you pay.
BedMart's 365 Night Comfort Guarantee is exchange-only, not a money-back trial: one-time mattress exchange within 365 nights of original purchase, with a required minimum 30-night break-in. The handling fee is $299.95 within the local delivery zone; exchanges outside the local zone pay current delivery rates.
Guarantee applies to the mattress only; stained or unsanitary mattresses cannot be exchanged or warranted; exchanged mattresses and all sales tagged outlet, clearance, floor model or as-is are final sale with no manufacturer warranty. No restocking percentages, refund mechanics or multi-exchange rights were published beyond these terms. Always re-check the live guarantee text before purchase in case terms change.

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.
Local delivery covers Oregon, SW Washington and Hawaii via BedMart trucks as soon as next day: free smartDROP threshold service (factory packaging left at door, garage or first-floor weather-protected area; no room placement, unpacking or assembly) and free white-glove mattress delivery on purchases of $1,499.95-plus after discounts (a $149.95 value; 2-hour window; unpacking and setup), all Qube Queens qualify.
Old-mattress set removal service costs $35 per piece (mattress, boxspring, standard metal frame). Standard bed-in-a-box courier shipping runs free within 5-10 days to 48 states (no Alaska); oversized flat-rate shipping averages 1-2 weeks in the contiguous US. Free warehouse pickup is available at Wilsonville OR plus Central OR, Oahu, Maui, Kauai and Big Island warehouses.
Frame, foundation and adjustable-base add-ons are offered at checkout; confirm exact fees and windows by ZIP before paying.
Typical wait: 5 to 10 days

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.
Every Qube mattress carries a 20-year non-prorated manufacturer warranty per all seven BedMart product pages.
BedMart's warranty page adds: the manufacturer alone honors and fulfills the warranty; coverage generally targets measurable structural defects and body impressions over 1.5 in on quilted tops and 0.75 in on memory foam, not gradual comfort loss; excluded items generally include stains, burns, mold, firmness preference, improper foundation damage, handles and misuse; keep receipts, warranty paperwork and sewn-in law tags (removal can void coverage); free claim-filing help is offered via MyMattressWarranty.com.
Per-model warranty cards, sag minimums, foundation requirements and claim remedies are Not published as of Sept 2026; read the card packed with your exact model.
Covered when the dip is deeper than 1.5 in on quilted tops, 0.75 in on memory foam, measured with nobody on the bed.
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.
Measure from the edge down to the deepest point, then photograph the ruler for your claim.

Customer reviews and complaints
Why this matters to you: Star ratings depend on who posts and where. Read the low-star reviews for patterns, not just the average.
No star ratings, review counts or written reviews were displayed on any of the seven live Qube product pages retrieved (CoreQUBE shows an empty review form; Q and A sections show no questions yet), and no third-party ratings for Qube Sleep on Google, BBB, GoodBed, Sleep Foundation, Sleepopolis, Mattress Clarity or RTINGS were found, so aggregate scores and complaint themes are Not published as of Sept 2026.
BedMart-level context only: family-owned chain since 1992 advertising 40-plus stores; brand-page claims of satisfaction and restorative sleep are marketing, not review data. Tip: read recent BedMart store and site reviews for your exact model before buying, since house-brand builds rotate and older feedback may describe different constructions.

Where can you try and buy the mattresses?
Why this matters to you: Where you buy sets the price, the trial and who handles problems. Check the seller's terms, not just the brand's.
Try and buy exclusively through BedMart: 40-plus family-owned stores across Oregon and Hawaii with delivery also serving SW Washington (find stores via shopbedmart.com locator; phone (503)-546-3300), plus online purchase at shopbedmart.com with ZIP-based local inventory and delivery availability. Test each finalist in store for 10-plus minutes in your sleep position and confirm feel against the on-page comfort graphics.
Qube Sleep has no standalone DTC site and no third-party dealers were found; BedMart's brand page says Qube is sold exclusively through authorized dealers. Sibling lines sharing the floor and in some cases the maker include Sound Sleep Products (named as a Qube manufacturer), Parklane, BedTech, King Koil, Kingsdown, Sealy and Tempur-Pedic.

Qube Sleep 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 Tempur-Pedic, Sealy, Kingsdown and King Koil sold in the same BedMart stores: Qube is the house-brand cooling-gel alternative, usually priced below Tempur-Pedic flagships but above Sealy and King Koil promoters, trading national-brand R and D plus review depth for exclusive gel-cube construction and a 20-year non-prorated term; head-to-head comfort winners are Not published as of Sept 2026.
Versus DTC gel and hybrid brands (Purple, Casper, Nectar, Saatva): Qube trades bed-in-a-box convenience and free-return trials for in-store testing, local white-glove delivery and exchange rights. Versus furniture-store house brands (Bob-O-Pedic, Ashley, Denver Mattress): all compete on store testing over published specs, with Qube differentiating on patented gel cubes and graphite cooling bands.
Versus latex specialists: only Indulge and the flagships carry Talalay latex, not full-latex builds.
Competitor details reflect published prices and specs on the date shown. Mattress brands may update prices and trial terms over time.
