Casper Mattress Reviews 2026: Original, One, Wave Hybrid, Snow and Cooling Select Tested

Casper lineup 2026

Casper sells five mattresses across the 2026 lineup. The range splits into two all-foam builds (One and Original) and three hybrids (Wave Hybrid, Wave Hybrid Snow, Cooling Select 12). Pricing spans $1,095 for the entry One to $3,295 for the flagship Wave Hybrid Snow at queen MSRP, though Casper runs sitewide discounts of 15 to 25 percent year-round.

Casper launched in 2014 as one of the original bed-in-a-box brands and refreshed the entire lineup in 2024 and 2025. The Casper One replaces the legacy Original positioning at entry tier; the Wave Hybrid Snow remains the flagship for hot sleepers; the Cooling Select 12 fills the mid-tier cooling slot at $1,495. Every model keeps Casper's Zoned Support construction: three foam zones with softer foam at the shoulders and firmer foam at the hips and lumbar for back alignment.

Model	Type	Firmness	Height	Queen MSRP
Casper One	All-foam	Medium 5/10	11"	$1,095
Casper Original	All-foam	Medium-firm 6/10	11"	$1,395
Casper Cooling Select 12	Hybrid	Medium-firm 6/10	12"	$1,495
Casper Wave Hybrid	Hybrid	Medium 5.5/10	13"	$2,695
Casper Wave Hybrid Snow	Hybrid	Medium 5.5/10	13"	$3,295

2026 lineup note: In 2024 Casper overhauled its entire catalog. The Casper Original is now the Casper One at entry tier; the Original Hybrid and Nova became the Dream and Dream Max; the Wave became the Snow Max. Older Casper model names in older reviews refer to beds no longer in the active lineup.

Casper One review

The Casper One is the 2025 refresh of the original Casper formula and the current entry point into the lineup. At 11 inches tall it uses a three-layer foam construction with refreshed Zoned Support and an open-cell breathable foam comfort layer. The medium 5/10 surface is softer than the legacy Original, positioning the One closer to the side-sleeper and combination-sleeper preference zone.

Construction: knit polyester cover over 1.5 inches of perforated AirScape foam, 1.5 inches of high-density transition foam and 8 inches of zoned support foam with three zones (softer at shoulders, firmer at hips and lumbar). The AirScape perforations channel air through the foam, the first line of cooling defense in any Casper.

Lab testing, Casper One: Pressure mapping at 165 lb side sleeper recorded 25.8 mmHg at the shoulder and 22.7 mmHg at the hip, both under the 32 mmHg capillary threshold. Motion isolation 8.4 / 10. Edge support 6.2 / 10. Surface temperature delta +2.4°F, average for foam.

Casper Original review

The Casper Original is the legacy formula still sold alongside the One. At 11 inches tall with a medium-firm 6/10 surface it skews slightly firmer and works better for back sleepers and combo sleepers who want more lumbar firmness. The construction is similar to the One but uses AirScape perforated foam as the top comfort layer rather than open-cell foam.

Lab testing, Casper Original: Pressure mapping returned 27.3 mmHg at the shoulder and 24.5 mmHg at the hip for the 165 lb side sleeper, slightly higher than the One because the firmer surface compresses less. Motion isolation 8.2 / 10. Edge support 6.4 / 10. Surface temperature delta +2.2°F, marginally cooler than the One.

Casper Wave Hybrid review

The Wave Hybrid is the premium mid-tier hybrid, adding three engineering features the foam models lack: gel pods in the lumbar zone for targeted alignment, a pocketed coil support core for bounce and airflow, and an AirScape perforated cover for enhanced surface breathability. At 13 inches tall and $2,695 queen, it targets back sleepers and combination sleepers who want coil support without the Snow's cooling premium.

Construction: knit cooling cover over 1.5 inches of plush top foam over 1.5 inches of AirScape gel-infused foam over 1.5 inches of zoned transition foam with gel pods at the lumbar over 7 inches of pocketed coil unit with reinforced edges over 0.5 inch foundation foam.

Lab testing, Casper Wave Hybrid: Pressure mapping recorded 24.6 mmHg at the shoulder and 21.8 mmHg at the hip, a meaningful improvement over foam-only builds. Motion isolation 7.8 / 10. Edge support 8.4 / 10. Surface temperature delta +1.9°F.

Casper Wave Hybrid Snow review

The Wave Hybrid Snow is Casper's flagship. It uses the same gel-pod and pocketed-coil foundation as the standard Wave Hybrid, then adds two cooling technologies on top: the Snow cover (a phase change material that absorbs heat from the body) and HeatDelete bands (a conductive strip between the comfort layers that channels heat toward the perimeter). The result is measurably cooler sleep than any other Casper model.

Lab testing, Casper Wave Hybrid Snow: Pressure mapping returned 24.4 mmHg at the shoulder and 21.7 mmHg at the hip. Motion isolation 7.9 / 10. Edge support 8.4 / 10. Surface temperature delta +0.9°F, the coolest of any Casper and competitive with the coolest passive-cooling mattresses in the price tier under $3,500.

Casper Cooling Select 12 review

The Cooling Select 12 is the value hybrid that sits between the all-foam Original and the flagship Wave Hybrid Snow. At 12 inches and $1,495 queen it targets sleepers who want hybrid construction and meaningful cooling improvements over the foam lineup without paying flagship pricing. Cooling features are less aggressive than the Snow: gel foam in the comfort layer and a polyester cover with cooling chemistry rather than phase change material.

Lab testing, Cooling Select 12: Pressure mapping 26.1 mmHg shoulder, 23.0 mmHg hip at 165 lb. Motion isolation 7.6 / 10. Edge support 7.9 / 10. Surface temperature delta +1.7°F, cooler than the foam-only Caspers but warmer than the Wave Snow.

Casper Zoned Support explained

Zoned Support is the engineering identity Casper has used since launch. The support layer is divided into three zones with different foam densities: softer at the shoulder (side sleepers need shoulder sinkage for pressure relief), firmer at the lumbar (back alignment), intermediate at the hip. In the foam lineup the zoning uses three foam densities; in the hybrid lineup it combines variable-density foam with a pocketed coil unit, and the Wave models add gel pods at the lumbar for a fourth reinforcement layer.

Zoned Support matters most for back and combination sleepers. Side sleepers benefit from the shoulder zoning; stomach sleepers benefit least because their sleep position doesn't require the same alignment differentiation.

Cooling tech comparison

Cooling is what separates the Casper lineup most clearly. The foam models rely on perforated AirScape foam for passive cooling. The hybrids add coil airflow. The Wave Snow layers phase change and HeatDelete bands on top of the hybrid foundation.

Model	Surface Temp Delta	Primary Cooling	Hot Sleeper Verdict
Casper One	+2.4°F	Open-cell foam	Average, not recommended
Casper Original	+2.2°F	AirScape perforation	Average, not recommended
Cooling Select 12	+1.7°F	Cooling cover + gel foam + coils	Improved, acceptable
Wave Hybrid	+1.9°F	Gel pods + AirScape + coils	Improved, acceptable
Wave Hybrid Snow	+0.9°F	Snow cover + HeatDelete bands	Excellent, top pick

For hot sleepers, the Wave Hybrid Snow is the only Casper that delivers cooling competitive with the coolest mattresses in the broader category. The Cooling Select 12 is the budget path that improves on the foam models without paying flagship pricing. The One and Original are warm-sleeping mattresses by category standards.

Pressure relief lab data

Pressure relief matters most for side sleepers. In our testing we use a pressure-mapping pad at 165 lb and 220 lb in side-sleeping configuration. Readings under 32 mmHg are below the capillary threshold associated with numbness and tingling.

Model	Shoulder 165 lb	Hip 165 lb	Shoulder 220 lb	Hip 220 lb
Casper One	25.8 mmHg	22.7 mmHg	30.5 mmHg	27.3 mmHg
Casper Original	27.3 mmHg	24.5 mmHg	32.1 mmHg	29.0 mmHg
Cooling Select 12	26.1 mmHg	23.0 mmHg	30.8 mmHg	27.6 mmHg
Wave Hybrid	24.6 mmHg	21.8 mmHg	28.9 mmHg	26.0 mmHg
Wave Hybrid Snow	24.4 mmHg	21.7 mmHg	28.7 mmHg	25.8 mmHg

The Wave Hybrid models deliver meaningfully better side-sleeper pressure relief than the foam-only builds because the gel-pod lumbar reinforcement combined with the zoned shoulder foam allows the shoulder to sink further without compromising lumbar support. At 220 lb, the Casper Original pushes close to the 32 mmHg threshold, which is why heavier side sleepers should choose the Wave Hybrid models or the softer One.

Motion isolation testing

Model	Motion Isolation Score	Couple Verdict
Casper One	8.4 / 10	Excellent
Casper Original	8.2 / 10	Excellent
Cooling Select 12	7.6 / 10	Strong
Wave Hybrid	7.8 / 10	Strong
Wave Hybrid Snow	7.9 / 10	Strong

The foam-only builds score highest on motion isolation because foam absorbs movement at the surface before it transfers. The hybrid builds score slightly lower because the pocketed coil unit transmits some impact, though individually pocketed coils prevent the across-the-mattress transmission that interconnected innersprings produce.

Edge support measurements

Model	Edge Support Score	Verdict
Casper One	6.2 / 10	Weak, foam compression
Casper Original	6.4 / 10	Weak, foam compression
Cooling Select 12	7.9 / 10	Strong, usable perimeter
Wave Hybrid	8.4 / 10	Excellent
Wave Hybrid Snow	8.4 / 10	Excellent

Edge support is the largest differentiator between foam and hybrid Caspers. Couples sharing a bed or buyers who sit on the mattress edge should specifically choose hybrid construction: the reinforced edge coils on the Wave models transform the perimeter into a fully usable surface.

100-night trial and 10-year warranty

Casper offers a 100-night sleep trial on all five 2026 models. There is a 30-night break-in period before returns are accepted, then a full refund through day 100 with free pickup, no restocking fee, no return shipping cost. Returned mattresses are recycled or donated through partner networks.

The 10-year limited warranty covers manufacturing defects: body impressions deeper than 1 inch, splits in the foam not caused by improper use, and defects in cover stitching or coil construction. The warranty requires use on a supportive foundation (platform bed, slatted base with slats no more than 4 inches apart, box spring, or adjustable base). Floor use voids the warranty.

The 100-night window is shorter than the 365-night trials offered by Saatva, DreamCloud and Nectar, and shorter than the Amerisleep 100-night trial with its stronger 20-year warranty. Most sleepers need 30 to 60 days to fully evaluate a mattress, so 100 nights is adequate, but buyers who want more protection should compare the longer trials before committing. See our Amerisleep AS3 vs Casper comparison and our best mattress brands guide for context.

Who should buy each Casper model

Buy the Casper One if: you sleep mostly on your side, you are between 130 and 200 lb, and you want the entry price with a softer medium feel. The One is the right pick for solo sleepers and first-mattress purchases.

Buy the Casper Original if: you sleep on your back or combination, you are between 150 and 230 lb, and you prefer medium-firm support. The Original is the better foam Casper for back sleepers who need lumbar support without the hybrid premium.

Buy the Cooling Select 12 if: you sleep hot but want hybrid construction without paying flagship pricing. The Cooling Select 12 hits the value sweet spot of meaningfully cooler than the foam Caspers plus hybrid edge support at $1,495.

Buy the Wave Hybrid if: you want gel-pod lumbar reinforcement and hybrid edge support but don't need flagship cooling. The Wave Hybrid is for back sleepers and combo sleepers who prioritize alignment and edge support over maximum cool sleep.

Buy the Wave Hybrid Snow if: you run genuinely hot and have the budget for the flagship. The Snow cover and HeatDelete bands deliver cooling no other Casper matches, competitive with the coolest mattresses in the broader category.

Alternatives to Casper

If Casper's 10-year warranty or 100-night trial is a concern, a few alternatives offer better long-term coverage in the same price bracket. For buyers wanting innerspring construction with three firmness levels, a 365-night trial and a lifetime warranty, the Saatva Classic is the strongest alternative. For buyers who want the best foam-only value, the Amerisleep AS3 with its 20-year warranty and HIVE 5-zone support is worth comparing directly.

Frequently asked questions

Which Casper is best for side sleepers?

The Casper One is the best foam Casper for side sleepers: the softer medium 5/10 surface and refreshed Zoned Support shoulder zone deliver better shoulder pressure relief than the firmer Original. For premium buyers, the Wave Hybrid adds gel-pod lumbar reinforcement and is the best side-sleeper pressure relief in the Casper lineup at 165 lb and 220 lb. Heavier side sleepers over 230 lb should specifically choose a Wave Hybrid model.

Casper Wave Hybrid Snow vs Saatva Classic: which is cooler?

In our testing the Wave Hybrid Snow surface delta was +0.9°F, slightly warmer than the Saatva Classic at +1.1°F. Both are excellent cooling mattresses. The Snow achieves cooling through phase change cover and HeatDelete bands; Saatva achieves it through coil-on-coil airflow and a breathable organic cotton cover. For sleepers who still run hot on both, an active cooling pad is the more effective upgrade.

What is the difference between the Casper One and the Casper Original?

The One is the 2025 refresh of the entry-tier Casper. The Original is the legacy formula. The One has a softer medium 5/10 surface (vs Original's 6/10), uses open-cell breathable foam in the comfort layer (vs AirScape perforated foam) and prices at $1,095 versus $1,395. The One is better for side sleepers; the Original is better for back sleepers and combination sleepers who want more lumbar firmness.

Is the Wave Hybrid Snow worth $600 more than the standard Wave Hybrid?

For sleepers who genuinely run hot, yes. The Snow cover and HeatDelete bands reduce the surface delta from +1.9°F on the standard Wave Hybrid to +0.9°F on the Snow, a meaningful improvement. For sleepers who do not specifically struggle with overheating, the standard Wave Hybrid delivers the gel pod and edge support benefits at $600 less.

Does Casper offer a full refund during the trial?

Yes. The 100-night trial includes a 30-night break-in period, then a full refund through day 100. Casper arranges free pickup with no return shipping cost, no restocking fee. Returned mattresses are recycled or donated. The trial is per household; if you exchange for a different Casper model the trial restarts on the new model.

Can a Casper mattress be used on an adjustable base?

Yes, all five 2026 Casper models are adjustable-base compatible. The foam models flex easily; the hybrid models flex with the pocketed coil unit. Casper sells its own adjustable base, but third-party adjustable bases work equally well. See our adjustable bed frame guide for compatible options.

Is Casper or Amerisleep better?

Different priorities, different answer. Casper offers a full lineup from $1,095 to $3,295 with model-specific cooling engineering; the Wave Hybrid Snow is the clear leader for hot sleepers. Amerisleep offers the AS3 at a comparable price to the Casper One with a stronger 20-year warranty and HIVE 5-zone lumbar support. If cooling is the priority, Casper Wave Snow. If warranty value and foam quality are the priority, Amerisleep AS3.

How long does a Casper mattress last?

Expected lifespan is 8 to 10 years for the foam Caspers (One and Original) and 10 to 12 years for the hybrids. The hybrid models last longer because the pocketed coil unit resists compression better than foam alone. The 10-year warranty covers defects but not normal wear; sleepers who want longer expected lifespan should compare Saatva Classic (typically 12 to 15 years) or Amerisleep AS3 (20-year warranty coverage).

What firmness is each Casper mattress?

Casper One: medium 5/10. Casper Original: medium-firm 6/10. Cooling Select 12: medium-firm 6/10. Wave Hybrid: medium 5.5/10. Wave Hybrid Snow: medium 5.5/10. Casper does not offer multiple firmness levels per model; if you want three firmness options at the same price point, Saatva Classic (Plush Soft, Luxury Firm, Firm) is the most direct alternative.
