Casper Mattress Reviews 2026
Casper mattress reviews point to a solid, medium-feel foam and hybrid line for average sleepers who want a safe pick, with real caveats on sinkage and firmness. We rated it from the line's Amazon listings, specs and buyer feedback on six criteria.
Our verdict: Recommended 66/100
Consistent 4.4-star ratings and a stated warranty make it a safe medium-feel pick, but owners disagree on firmness and some report sinkage. Based on 4 models, 8,457 Amazon reviews, 137 search results and 28 buyer questions.
The verdict
Is Casper worth buying?
RecommendedHow it scores
Our score66/100
For most average-weight sleepers who want a medium or medium-firm bed, yes. The Casper mattress line across Amazon holds a 4.4 average from 8,457 reviews, and the two Original 11" models and the all-foam Element each sit at 4.3 to 4.4 stars. That kind of consistency across different builds is rarer than it sounds in this category.
The listings state a breathable open-cell Flex Foam, motion isolation, and Zoned Support on the Original models that puts firmer foam under the hips, waist and lower back. A 10-year warranty is stated on 22 of 24 listings.
The reservation is feel. Outside owners split on it: some call it too soft and say it caused back pain, others call it firm enough to cause hip pain. One owner reports excessive sinkage at average weight. And the Element Hybrid has only six reviews, so we can't vouch for it yet. Check the exact model before you buy.
- Average-weight sleepers wanting a medium or medium-firm foam bed
- Couples who care about motion isolation
- Back and combination sleepers who want zoned lower-back support
- Buyers who want a stated 10-year warranty
- Heavier sleepers who need a very firm, non-sinking bed
- Buyers sensitive to new-foam smell
Who is behind Casper
Casper is a well-known online mattress brand with a large search presence, and its mattresses show up in coverage from outlets such as Wirecutter and Tom's Guide. It also sells through Costco and Home Depot, and runs its own site with phone and chat support seven days a week.
The record isn't spotless. Search results surface Better Business Bureau complaints and Trustpilot posts about lumps in hybrids, and one Reddit owner calls the brand a scam that no longer builds beds to its old standard. That's one voice, but it fits a pattern of mixed long-term feedback.
On Amazon, the warranty is stated as 10 years on 22 of 24 listings. Read the terms on the exact listing you buy, since we can't see claim outcomes. One Reddit thread also says Casper pillows lost their trial and returns, a reminder to confirm return terms for your specific purchase.
The line
Casper's models and how they differ
The four models share the same core pitch: open-cell Flex Foam meant to sleep cooler than traditional memory foam, layered foam for motion isolation, and a medium to medium-firm feel. They split on two choices. First, all-foam or hybrid with coils. Second, the Element (simpler, medium) or the Original 11" (zoned support, a touch firmer).
If you want the simplest bed from this line, the Element Memory Foam is the biggest seller and carries a stated medium feel. If you want targeted lower-back support, the Original 11" models state Zoned Support. Choose hybrid if you prefer bounce and airflow through coils, foam if you prefer a slower, hugging feel. Sizes run from Twin to California King across the models.
Element Memory Foam Mattress
The entry all-foam bed and the line's largest seller, at about a third of sales. It has a medium feel and is rated 4.4 stars from 958 reviews. The listing states breathable open-cell foam and motion isolation. A fit for average sleepers who want a straightforward foam bed. It comes in Grey.
Original 11" Hybrid Mattress
An 11-inch hybrid with encased coils and Zoned Support, medium feel. It is rated 4.3 stars from 1,305 reviews, the lowest of the three well-reviewed models. One Reddit owner reported a sinkhole after three months on the Original Hybrid. Best for sleepers who want coil bounce and zoned support.
Original 11" Memory Foam Mattress
The 11-inch all-foam with Zoned Support and a medium-firm feel, rated 4.4 stars from 1,058 reviews. The listing says firmer foam sits under the hips, waist and lower back. Wirecutter describes the 11-inch model as medium-firm with bounce and cushion. Fits back sleepers and anyone who wants spinal support in foam.
Element Hybrid Mattress
A hybrid with pocketed springs and a medium-firm feel, unlike the medium all-foam Element. It has only six reviews and a 3.7 rating, so the evidence is thin. The listing states airflow and a responsive feel with some bounce. Treat it as unproven until more owners weigh in.

Medium feel, but owners disagree
The line sits at medium or medium-firm, and the listings call it suited to all sleepers. Tom's Guide found the One skews slightly firmer than rated. Owners split: one found a Casper too soft and ended up with back pain, another says it's firm and causes sacroiliac pain, and one reports a Wave Hybrid too soft. Another says it suits thin people but sinks for average weight. Try the exact model with a good return window.
- Medium to medium-firm across the four models
- Owner feedback on firmness is split
- Average-weight and heavier sleepers report sinkage
Long-term reports are mixed
The listings state a 10-year warranty on 22 of 24 listings, which sets a durability expectation, but the terms matter. One Reddit owner used a Casper for the better part of ten years with no issues and called the quality fine, not exceptional. Against that, a Reddit owner reported a sinkhole in an Original Hybrid after three months, and a Trustpilot post describes a lump in a one-year-old hybrid.
- A stated 10-year warranty on most listings
- One long-term owner reports a decade without issues
- Hybrid lumps and sinkholes show up in complaints
Two foam beds and two hybrids
Casper's four models split evenly: the Element and Original 11" Memory Foam are all-foam, while the Original 11" Hybrid and Element Hybrid add coils. The listings describe the hybrids as using encased or individually pocketed springs under foam. The foam models carry the better-documented ratings, since the Element Hybrid has just six reviews. The Original Hybrid is the one with reported sinkhole complaints.
- Two all-foam and two hybrid models
- Coil hybrids add bounce and airflow
- The Element Hybrid has too few reviews to judge
Open-cell foam aimed at cooler sleep
Every listing we read leads with airflow: Flex Foam is described as breathable open-cell foam that keeps air moving, and the Element Hybrid adds a top layer built for airflow. That's the manufacturer's claim, and the listings give no temperature figures. Owner opinions differ: one Reddit buyer called a Casper a raging inferno, while a coil count and cooling cover aren't stated for these models.
- Airflow is the headline claim on all four listings
- No temperature measurements are given
- At least one owner reports it sleeping hot
Certifications aren't stated on these listings
The listings we read don't state a CertiPUR-US certification or any off-gassing information, so check the exact listing before buying. One Reddit owner of a Casper Dream wrote that its out-of-the-box smell is well documented. A mattress-review site notes Casper uses certified covers and foams but that some Caspers contain fiberglass. Unbox in a ventilated room.
- No certification stated on the listings we read
- Some owners report a strong new-bed smell
- Ask whether your model contains fiberglass
What Casper owners say
Across 8,457 Amazon reviews the line averages 4.4 stars, and the outside comments are more divided than that number suggests.
- Owners like the balance of softness and support, and Home Depot buyers say it suits several sleeping positions.
- One Reddit owner got the better part of ten years out of a Casper and another likes an older one enough to upgrade to a Queen.
- Reviewers describe Zoned Support as helpful for back and joint pain.
- Sinkage for average-weight sleepers and a Casper Original Hybrid sinkhole after three months.
- Firmness misses in both directions: too soft for back pain for some, too firm for sacroiliac pain for others.
- Some owners dislike the new-bed smell and report heat.
Alternatives
When another brand fits better
If you weigh well above average or want a truly firm bed, look for a brand that states a higher firmness rating and a dense support core, since owners report sinkage on Casper. Shoppers sensitive to smell should look for a listing that states CertiPUR-US certification clearly and says whether fiberglass is in the fire barrier.
If you want a hybrid with proven reviews, look for a model with a deeper review pool than the Element Hybrid's six, and one with a coil count stated. Buyers who want an adjustable or flippable feel won't find that in this line.
FAQ
Casper questions buyers ask
01 Is Casper a good mattress company?
Mostly yes on ratings: its Amazon line averages 4.4 stars from 8,457 reviews with a 10-year warranty stated on 22 of 24 listings. But owner complaints about sinkage and lumps in hybrids, plus BBB complaints in search results, mean you should check the exact model and return terms.
02 What are some common complaints about Casper mattresses?
Owners mention sinkage at average weight, firmness that missed expectations in both directions, and sinkholes or lumps in hybrids. Some report a strong new-bed smell and heat. A Reddit owner reports a Casper Original Hybrid sinkhole after three months.
03 What is a Casper mattress made of?
The listings describe layered foam with breathable open-cell Flex Foam on top. The Original 11" models add Zoned Support, and the hybrids sit on encased or individually pocketed coils. The listings don't state foam density or certifications.
04 What Casper mattress is good for side sleepers?
Sleepopolis says the Casper One accommodates light and average-weight side sleepers without shoulder sensitivities, and Tom's Guide found the One skews slightly firmer. Among these Amazon models, the medium Element is the softer pick. Heavier side sleepers report sinking too far.
05 Is the Costco Casper the same as the original?
Not necessarily. Costco sells models such as the Casper Cooling Select 12", which isn't one of the Amazon models reviewed here. Compare the layer descriptions and firmness on each listing instead of assuming they match.
06 Can I refund a Casper?
Return terms depend on where you buy. For Amazon purchases, check the listing's return terms. A Reddit post warns that Casper pillows lost their trial and returnable status despite the site's free-returns wording, so confirm before you buy.
Where to buy Casper
Amazon carries the Casper line covered here, with 24 live listings across four models and sizes from Twin to California King. Costco and Home Depot also sell Casper mattresses, though their models and terms can differ. Check current pricing and return terms on the listing before you buy.
