by The Casper Snow Max is a 14-inch cooling hybrid at $4,120 in Queen — the most expensive mattress Casper sells, built for hot sleepers who want a soft, conforming surface with zoned support underneath. You would buy it for the full Snow Technology stack (QuickCool cover, phase-change material, six HeatDelete bands), Zoned Support Max with seven zones, and simple ownership terms: 100 nights, free returns after the first 30, a full refund, a 10-year limited warranty. You would think twice if you want a firm bed, if you expect a showroom mattress to feel the same at home, or if you expect a dramatic temperature drop — the cooling number is Casper’s own test, and a minority of owners say the bed still slept warm.
How we compared
I compared Casper’s product specifications and size selector with its trial, return, delivery and warranty terms, then checked the details against the retailer listing and customer reviews. I did not sleep on this mattress or measure its firmness, temperature, motion transfer or edge support; the advice below is based on the published medium-soft feel and construction.
What you are buying: Casper’s most over-built mattress
The Snow Max is a 14-inch hybrid with 8 layers and a medium-soft, conforming feel — the memory-foam hug rather than the responsive bounce of the Dream Max beside it. Casper builds it around two systems: Zoned Support Max for the spine, Snow Technology for the heat.
Under your body sits Zoned Support Max: two layers of ergonomic foam, one precisely cut into channels, working with seven support zones so shoulders sink and hips stay lifted. Below that, Flex Coils sit over a durable polyurethane base inside Casper Core Edge foam, so the perimeter stays usable for sitting and sleeping.
The spec tab lists the cooling layers plainly: a top layer of breathable memory foam coated with phase-change cooling material, a second layer of zoned memory foam threaded with thin thermal bands of flexible graphite (the HeatDelete bands), a third layer of contoured memory foam, then the foam-and-spring base. Casper describes the mattress as fiberglass-free and designed and assembled in the USA.
Every size, every price
Casper’s size selector lists six sizes, all 14 inches tall. The weight matters — the King-class boxes are heavy:
| Size | Dimensions (W x L x H) | Weight | Price |
|---|---|---|---|
| Twin XL | 38 x 80 x 14 in | 73 lb | $3,370 |
| Full | 53 x 75 x 14 in | 92 lb | $3,870 |
| Queen (60 x 80 in) | 60 x 80 x 14 in | 111 lb | $4,120 |
| King | 76 x 80 x 14 in | 139 lb | $5,120 |
| California King | 72 x 84 x 14 in | 139 lb | $5,120 |
| Split King | 76 x 80 x 14 in | 139 lb | $6,740 |
Casper’s live page is currently promoting a free adjustable base with purchase and also advertises bundle savings and Affirm financing. The base shown with the Snow Max is Twin XL, so treat it as a bonus only if that size works for your setup. Promotions and financing eligibility can change; confirm the selected size and order total before checkout.
How firm is it, and which sleep positions suit it?
Casper rates the Snow Max medium-soft and calls the feel conforming — you sink in rather than rest on top — and positions it for side and back sleepers. No numeric score is published, so the advertised label is the honest starting point:
- Side sleepers: the first position I would put this bed in. A medium-soft conforming surface lets a shoulder and hip drop in instead of staying propped up.
- Back sleepers who want contouring: a good match — the seven-zone layer keeps hips from sinking while the lumbar stays filled in.
- Stomach sleepers: not the bed I would start with. Soft under the hips is the wrong direction for this position, whatever the zoning does.
- Couples: a foam-and-coil build with a foam-encased edge, the standard way to keep one partner’s movement from crossing the bed.
My practical advice: try the medium-soft feel in a Casper store if you can. The showroom gives you a chance to check whether you like the conforming surface before committing to a high-priced mattress.
What the cooling actually promises
Casper states that Snow Technology is built to keep you 6º cooler for 12+ hours, and footnotes that this is based on Casper testing comparing Casper products with HeatDelete to those without — a comparison between the brand’s own beds, not a room-temperature measurement of your bedroom.
Cooling: a QuickCool cover, extra phase-change material and six HeatDelete bands; Casper does not publish an independent temperature figure for this model. Motion transfer and edge support: Casper says its encased coils help limit partner disturbance and its Core Edge foam supports the perimeter. Those are construction claims, not measurements of this mattress.
The page also quotes Consumer Reports’ top-rated hybrid mattress of 2026, with Casper’s footnote that Consumer Reports does not endorse products or services, and publishes a keep rate: 92% of customers keep their mattress, a 12-month cohort that bought between May 2025 and April 2026.
The trial, the returns and the warranty: the part that decides a $4,000 purchase
Casper’s ownership terms are the strongest argument for buying direct:
| What the policy actually gives you | Casper terms |
|---|---|
| Trial length | 100 nights, starting when the mattress is delivered |
| Minimum before you can act | 30 nights — returns are not accepted during the adjustment period |
| Return fee | None. No restocking, pickup or processing fee |
| How you get your money | A courier removes the mattress from your home and the original payment method is refunded in full |
| Exchange instead of refund | Supported: Casper places the new order, collects the old one, and refunds the first purchase within 3-5 business days of confirmed pickup. Returned mattresses are donated or recycled where possible |
| Warranty | 10-year limited, original purchaser only, non-transferable |
| What counts as a defect | A visible indentation greater than 1 inch not caused by an unsupportive base, foam that splits or cracks, or a flaw in the cover’s zipper |
Three clauses deserve a second read. Comfort preference and normal softening are explicitly not covered — too soft for you is not a defect. Coverage also depends on support: Casper requires a firm, solid-surface base capable of holding the mattress and sleepers, and a weak foundation that causes the sag can cost you the claim. Finally, Casper pays return shipping when a warranty claim needs the mattress sent back; a mattress bought on casper.com needs no registration, one bought from another retailer does. Clearance and Final Sale items can carry shorter terms, and trade customers get 3 years instead of 10.
Delivery: box at the door, or people who set it up
Free UPS ground shipping is available for mattresses in the contiguous US. Casper says in-stock orders are typically delivered within 2-8 business days after ordering; processing usually takes 1-3 business days, so allow for the full window. The brand says its mattress boxes weigh 47-139 lb depending on model and size; the Snow Max Queen is listed at 111 lb. Alaska and Hawaii mattress shipping costs $250 per mattress; Casper does not ship to APO or PO boxes or US territories.
Prefer not to unroll it yourself? In-Home Delivery and Setup runs $249: 2-4 weeks, a scheduled date, a four-hour window confirmed the day before, room-of-choice setup, packaging removal, and optional removal of your old mattress when that old bed was bought through Casper. A standalone LoadUp removal costs $150 in eligible areas outside California. Casper sells foundations, slatted frames and adjustable bases alongside the mattress and describes them as working with any Casper bed.
Want a retailer option? Mattress Warehouse lists the Queen at $4,120 and advertises Free White Glove Delivery and a 120-day, 100% Comfort Guarantee on its product page. These are retailer terms, separate from Casper’s direct 100-night trial; read the retailer’s written conditions for your size and delivery area before ordering.
What Casper’s owner reviews can—and cannot—tell you
Casper displays 4.3 out of 5 stars from 386 Snow Max reviews. That is a useful signal that many buyers are satisfied, but it does not predict how this medium-soft feel will land for your body. The reviews displayed by Casper include strong comfort and cooling praise; treat individual reports as personal experience, not a performance test or a promise of pain relief.
How the Snow Max compares
Inside Casper’s own lineup, the Snow Max sits at the top of the Maxes tier — 14 inches, the most support, the most cooling, the highest price. Prices and ratings below are Casper’s own:
| Model (Queen) | Price | Feel | Height | Owner rating |
|---|---|---|---|---|
| Casper Snow Max | $4,120 | Medium-soft, conforming | 14 in | 4.3 / 5 (386) |
| Casper Dream Max | $3,370 | Medium-soft, responsive | 14 in | 4.3 / 5 (2,563) |
| Casper Snow | $2,720 | Medium, conforming | 12 in | 4.4 / 5 (1,072) |
| Casper Dream | $1,995 | Medium, responsive | 12 in | 4.5 / 5 (2,874) |
The Snow is the honest shortcut: same memory-foam cooling idea, 12 inches instead of 14, $1,400 less in Queen — you give up the seventh-zone Zoned Support Max layer and the strongest version of the cooling stack. The Dream Max is the move for people who dislike sink: same height, same support tier, responsive foam instead of conforming, $750 less.
Outside the brand, Cocoon vs Casper answers the value question — what a budget cooling foam bed gives up against a Casper — and Avocado vs Casper the materials question, natural latex and coils against foams and phase-change fabric. Our Casper mattress reviews page covers the rest of the lineup model by model, and Casper cooling technology explains QuickCool, phase change and HeatDelete in detail.
Who should not buy it?
- Skip it if you want a firm mattress. Medium-soft and conforming means you sink in; stomach sleepers and firm-bed sleepers have better options in Casper’s lineup.
- Skip it if you buy on showroom feel alone. The recurring complaint is that the Snow Max feels different at home than in the store — and this is the model where that costs most.
- Skip it if you need an independently measured cooling result. Casper’s 6º figure comes from its own comparison test; it is not an independent result.
- Skip it if your base is inadequate. The warranty expects a firm, solid-surface foundation; sag caused by a weak base is not covered.
- Skip it if $4,120 in Queen is the stretch. The Snow at $2,720 and the Dream Max at $3,370 do much of the same work, same trial and warranty.
- Skip it if you already know you dislike a conforming foam feel. Snow Max is built around contouring memory foam, not a buoyant, quick-response surface.
Frequently asked questions
How much is the Casper Snow Max?
Casper’s size selector lists Queen at $4,120, Twin XL $3,370, Full $3,870, King and California King $5,120, and Split King $6,740. Every size is 14 inches tall. Check the live cart for the selected size and any promotion.
Is the Snow Max firm or soft?
Casper labels it medium-soft with a conforming feel — expect more sink than on a firm or responsive foam surface. Comfort is personal, so use the trial terms if you cannot try it in a store.
Does it actually keep you cool?
Casper says Snow Technology keeps you 6º cooler for 12+ hours, based on Casper’s comparison testing of its own products with and without HeatDelete. That is not an independent measurement of how cool your bedroom or body will feel.
Can I return it if I do not like it?
Yes. After the 30-night adjustment period, inside the 100-night trial, Casper arranges a free courier pickup and refunds the original payment method in full — no restocking, pickup or processing fee.
How long is the warranty?
10 years, limited, original purchaser only and not transferable. It covers a visible indentation over 1 inch that is not the fault of a poor foundation, foam that splits or cracks, and zipper flaws — not comfort preference, normal softening, stains or abuse. Casper pays return shipping on a valid claim.
How does it arrive?
Free UPS ground delivery in the contiguous US, typically 2-8 business days after 1-3 days of processing. In-Home Delivery and Setup is $249 with a 2-4 week lead time and optional old-mattress removal.
Bottom line: the flagship for hot sleepers who like to sink
The Snow Max is the most mattress Casper builds: 14 inches, 8 layers, seven support zones, phase-change cover, six graphite thermal bands, encased coils and a foam edge, fiberglass-free and assembled in the USA. Queen at $4,120 puts it $1,400 above the Snow and $750 above the Dream Max, and the terms behind it are the easy part to like: 100 nights, free returns after 30, a full refund, and a 10-year warranty that pays its own shipping.
What I would weigh is narrower than the spec sheet: the medium-soft label is subjective enough that owners argue about it in both directions, and the cooling claim rests on Casper’s own comparison test. Sleep hot, like a bed you sink into, and can try it in a store first — it is the Casper to get. If either caveat sounds like you, the Snow or the Dream Max makes the same argument for less money.
