The Casper Original is the mattress that put bed-in-a-box on the map. A decade later, the category has caught up, the brand has been through bankruptcy and a private-equity buyout, and the lineup has been quietly reshuffled. The Original is still in the catalog, still around $1,095 for a Queen at MSRP, and still the default recommendation a lot of buyers land on when they start researching foam mattresses. The honest question now isn’t whether Casper invented the category. It’s whether the Original still earns a spot at the top of the list when Nectar, Tuft & Needle, and a handful of Amazon-only brands are all sitting in the same price band.

TL;DR verdict

The Casper Original is a competent all-foam mattress with a real signature feature, zoned support that’s softer at the shoulders and firmer under the hips. For back sleepers and combination sleepers who shift between back and side, that zoning does measurable work. But at roughly $1,095 for a Queen, it’s no longer the obvious value play in its segment: Nectar offers a longer trial and lifetime warranty for less, and Tuft & Needle undercuts it by several hundred dollars with a simpler, cooler-sleeping build. Get the Casper if zoned alignment is what you’re optimizing for. If you’re just looking for the best sub-$1,000 foam mattress, the math no longer points here automatically.

What it is

The Casper Original is an 11-inch all-foam mattress with three functional layers. The top is an Airscape perforated foam designed to move heat away from the body. Under that sits the part Casper has built its identity around: a zoned memory foam transition layer that’s engineered with three distinct firmness regions, softer at the shoulders, firmer under the hips and lower back, and softer again at the legs. Below that is a high-density polyfoam base that does the structural work of holding the mattress up and keeping the comfort layers from compressing through to the floor.

The pitch behind the zoning is straightforward: in a back-sleeping or side-sleeping position, your shoulders need to sink in to keep your spine neutral, while your hips need more pushback to prevent them from dropping below the line of your shoulders. A uniform foam slab makes one or the other a compromise. Casper’s argument is that engineered zones do both at once. Whether that argument lands for your body is the question the 100-night trial exists to answer.

Sizes run the standard range (Twin, Twin XL, Full, Queen, King, California King), with the comfort layer thicknesses identical across sizes; only the footprint changes. Firmness is tuned to roughly a medium, around a 6 to 7 on the standard 10-point scale, which puts it in the sweet spot for the largest single group of sleepers and explains why so many bed-in-a-box brands target the same number. The mattress is CertiPUR-US certified for foam content, which means third-party verification on restricted chemicals, heavy metals, and ozone depleters. A baseline you should expect from any reputable foam mattress at this price.

What owners consistently mention

Across long-form owner reviews, expert testing labs, and aggregated retailer feedback, a few patterns repeat often enough to take seriously.

The zoning shows up in real use. Back sleepers and combination sleepers who alternate between back and side report that the lumbar-to-hip transition feels supportive in a way generic foam doesn’t. Reviewers also flag good motion isolation. A partner getting in or out of bed registers as a faint shift, not a wave across the surface. That’s the all-foam trade everyone signs up for, and Casper executes it well.

Setup is uneventful. The mattress arrives compressed in a box, expands within a few hours, and is sleepable the same night. Off-gassing is mild and fades inside a week for most owners. Nothing about the unboxing experience surprises anyone who has bought a foam mattress in the last five years.

Heat is a real concern, but not a dealbreaker for most. The Airscape top layer helps, and the zoned construction sleeps cooler than a single slab of dense memory foam would. But it’s still memory foam, which traps body heat by nature. Independent testing labs consistently rate cooling as good but not great. Roughly one in twenty owners flag heat as bad enough to undermine sleep, a rate similar to the rest of the all-foam category. If you regularly wake up sweating on your current mattress, a hybrid with coil airflow is the safer bet.

Edge support is mediocre. Sit on the perimeter and the foam compresses noticeably. Sleep close to the edge and you’ll feel the surface give as your shoulder presses down. For solo sleepers on a Queen or King this is invisible. For couples where each person treats their side of the bed as fully usable real estate (including the last few inches). This is the limitation that pushes some buyers to a hybrid.

Long-term durability is the most honest concern. This is where reputation has shifted in the last few years. Owners report visible body impressions and softening sooner than they’d like. Lighter sleepers under 150 pounds often get six to seven years of comfortable use, average-weight sleepers four to six, and sleepers over 200 pounds sometimes report meaningful sag in three to four. Some of that is the physics of any all-foam mattress at this price; some of it is the gap between the foam densities Casper uses and what longer-lived foam mattresses spec. The 10-year warranty covers indentations deeper than one inch, but many owners report comfort decline well before they hit that visible threshold, which means the warranty is technically intact while the mattress no longer sleeps the way it did on day one. Worth knowing going in.

If the zoned support sounds like the right fit for how you sleep, it’s worth checking the current price. The mattress is sold direct on Casper’s site and through Amazon, and the cheaper of the two on any given week is the right one to buy. Check price on Amazon →

Who it’s for, who should skip

Get the Casper Original if: you sleep primarily on your back, or you’re a combination sleeper who shifts between back and side through the night and wants the engineered zoning to handle both positions. It also works well if you sleep with a partner and motion isolation matters, foam handles this natively, and Casper handles it as well as anything in the category. If you’re a lighter sleeper (under 150 pounds), the durability concerns soften, and you’re more likely to get a full warranty cycle out of it.

Skip the Casper Original if: you run hot and don’t want to manage your bedroom temperature aggressively. Skip it if you weigh more than 230 pounds and want a mattress that holds its shape past the four-year mark. You’ll be better served by a hybrid built specifically for heavier sleepers, or by a foam mattress with denser support layers. Skip it if edge support is high on your list, or if you sleep predominantly on your stomach. Medium-firm foam tends to let the hips drop below the shoulders, which is the opposite of what stomach sleepers need.

How it compares

Three direct competitors sit in the same shopping cart most of the time. Here’s how the Casper stacks up against each.

vs. Nectar Original (~$799 sale, $1,199 MSRP): This is the head-to-head most buyers actually face. The Nectar is a 12-inch slower-responding memory foam build with a deeper hug. The Casper is 11 inches with zoned engineering that holds the hips up rather than letting them sink. For pure pressure relief on the side, the Nectar wins; for back sleepers and combination sleepers who want neutral spinal alignment, the Casper has the edge. The bigger differentiator is the trial and warranty: Nectar offers 365 nights and a lifetime warranty against Casper’s 100 nights and 10 years. At a roughly $300 lower street price, that’s a hard combination to argue against unless the zoning is specifically what you’re after.

vs. Tuft & Needle Original (~$645): Tuft & Needle skips the engineered zones entirely and runs a simpler two-layer adaptive foam construction that’s lighter, more responsive, and consistently rated cooler than the Casper. It’s also several hundred dollars cheaper. You give up the zoned alignment story and a small amount of contouring; you get a more breathable mattress at a meaningfully lower price. For renters, guest rooms, and buyers who want a baseline good mattress without the brand premium, Tuft & Needle is often the smarter pick.

vs. Allswell and Leesa Original: Allswell (Walmart-owned) drops to under $400 for a Queen and gets you a hybrid coil-and-foam construction at the cost of finish quality and warranty terms, a real budget play, with the trade-offs that implies. Leesa Original sits at a similar price tier to Casper with a softer, less-zoned feel and a comparable trial period; it’s the closest direct comparison for buyers who want the Casper experience but find the Casper too firm under the hips. None of these competitors changes the core Casper question, which is whether zoned support is worth the price gap.

Trial, warranty, return policy

Casper offers a 100-night sleep trial. The brand asks you to try the mattress for at least 30 nights before initiating a return, a reasonable ask, given that most buyers need a couple of weeks to adjust to a new feel before they can fairly judge it. After night 30 and before night 100, you can return the mattress for a full refund. Casper coordinates pickup and donates the mattress; you don’t have to figure out disposal yourself. There are no return shipping fees in the contiguous US, which is the industry standard at this price point but worth confirming.

The 10-year limited warranty covers manufacturing defects in the foam, cracking, splitting, or sagging deeper than one inch that isn’t caused by an unsupportive base. Read the fine print: the warranty requires you to be using a compatible foundation (slats spaced no more than a few inches apart, or a solid platform), it’s not transferable if you sell the mattress, and you’ll need proof of purchase to file a claim. The one-inch sag threshold is worth understanding clearly, many owners describe meaningful comfort decline at half that depth, well before the warranty kicks in. The warranty is real, but it isn’t a guarantee that the mattress will sleep the same in year five as it did in year one.

Where to buy and price context

The Casper Original is sold direct on casper.com and through Amazon. Both channels carry the same mattress; the difference is which one is running a deeper promotion in any given week. Direct from Casper, the Queen typically lists at $1,095 MSRP and drops to roughly $895 to $995 during the brand’s regular sale cycles, which run often enough that buying at full MSRP is rarely necessary. Amazon pricing tracks the direct site closely, sometimes a touch lower, sometimes a touch higher, with the added benefit of Prime shipping if you’re already a member.

One pricing note: like Nectar and most of the bed-in-a-box category, Casper’s listed MSRP and its actual selling price are different numbers. Don’t let a countdown timer or a percentage-off banner pressure you into a same-day decision. The mattress will be on sale again next week. Buy when the price is right, not when the urgency banner is loudest.

Final verdict

The Casper Original is a solid, well-engineered foam mattress that does one thing better than most of its peers. Zoned support that holds back and combination sleepers in neutral alignment without forcing the hips to sink. That’s a real feature, not a marketing line, and it’s the reason to buy this mattress over a cheaper alternative. The cooling is decent, the motion isolation is excellent, and the build feels like a quality product when you sleep on it.

The reasons not to buy it are equally honest. Long-term durability is a real question for anyone over the lighter end of the weight range, with body impressions and softening showing up sooner than the 10-year warranty implies. The 100-night trial is shorter than the 365 nights Nectar offers at a lower price. And if you’re a back sleeper who doesn’t specifically need the zoning, Tuft & Needle delivers a similar core experience for several hundred dollars less. The Casper Original isn’t the obvious sub-$1,000 winner it was five years ago. It’s one of three or four reasonable choices, and the right pick only if its specific strengths match your specific sleep style.

Overall rating: 7.8 / 10. A capable mattress with a clear use case, just no longer the default. Check price on Amazon →
