Casper Element Mattress Review

Quick Verdict

The Casper Element is a good buy for back sleepers, combination sleepers, and couples under about 230 pounds each who want a simple, responsive foam mattress from an established brand without paying premium prices. It absorbs motion well, sleeps cooler than traditional memory foam, and doesn’t leave you feeling stuck.

Skip it if you’re a heavier sleeper, a strict side sleeper with broad shoulders, or someone who sits on the edge of the bed a lot. Two layers of foam in 10 inches don’t offer the deep pressure relief, edge support, or long-term support of a thicker hybrid. Hot sleepers should also consider a mattress with coils, which breathe better than any all-foam design.

Prices by Size

Casper excludes the Element from its sitewide sales, so the price is usually the same on Casper.com and Amazon. Not sure which size fits your room? Our mattress size chart has dimensions and room-size guidance.

Construction

The Element keeps things simple:

1. Knit cover. A soft, four-way stretch fabric that lets you feel the foam underneath. It’s not removable, so use a mattress protector.
2. Breathe Flex Foam comfort layer. Casper’s open-cell foam. Open-cell foam has more air pockets than traditional memory foam, so it lets heat escape more easily and springs back faster when you move.
3. Support foam base. A dense polyurethane foam that gives the mattress its structure and keeps you from sinking too far.

Casper’s more expensive mattresses add zoned support, more comfort layers, or coils. The Element doesn’t, and that’s how it hits its price.

Firmness and Feel

Casper calls the Element medium. In practice it sits in the middle of the firmness range for most people, with how firm it feels depending on your weight: lighter sleepers sink in less and find it firmer, while heavier sleepers press through the comfort layer and feel more of the base.

The feel is responsive: the foam contours to your body under pressure but rebounds quickly when you shift. If you’ve slept on a traditional memory foam mattress and disliked the slow, quicksand-like sink, the Element is noticeably bouncier. If you love that hugging feel, you may find it too plain.

Who It Suits, by Sleep Position

• Back sleepers. The best match. The medium feel lets the hips sink slightly while keeping the lower back supported.
• Combination sleepers. The responsive foam makes it easy to change positions.
• Stomach sleepers. Works for lighter stomach sleepers. Heavier stomach sleepers may find their hips sink too far, which strains the lower back; a firmer mattress is safer.
• Side sleepers. Light to average-weight side sleepers can be comfortable. Side sleepers with broad shoulders or hips often need a thicker comfort layer to relieve pressure.

Body weight matters. Thin, all-foam mattresses like the Element are best for people under roughly 230 pounds. Heavier sleepers generally need a thicker mattress, a hybrid with coils, or both, for adequate support and durability.

Motion Isolation, Temperature, and Edges

Motion isolation is a strength. Foam absorbs movement instead of bouncing it across the bed, so if your partner tosses and turns or gets up early, you’re less likely to feel it.

Temperature is better than traditional memory foam, thanks to the open-cell comfort layer, but it’s still an all-foam bed. Foam holds more body heat than the open space inside a coil layer, so very hot sleepers usually do better on a hybrid.

Edge support is the weak spot. Without a firm perimeter or coils, the edges compress when you sit on them, and you may feel like you’re rolling off when you sleep near the side. That matters most for couples on a full or queen and for anyone who sits on the edge to get dressed.

Setup and Off-Gassing

The Element ships compressed in a box. Unroll it on your bed frame or foundation, cut away the plastic, and let it expand. It’s usable within a few hours, but it can take up to a day or two to reach full height.

Like most new foam mattresses, it has a temporary “new mattress” smell when unboxed. Open a window and give it a day or two to air out. The CertiPUR-US certification means the foams are tested for emissions and made without certain chemicals, such as ozone depleters and some flame retardants.

Trial, Warranty, and Returns

Casper offers a 100-night trial and a 10-year limited warranty on the Element. Give any new mattress at least two to four weeks before deciding; your body takes time to adjust. Return terms can differ depending on whether you buy from Casper, Amazon, or another retailer, so check who sells and fulfills your order and read the policy at checkout.

Casper Element vs. Other Options

The Element Hybrid adds coils for better airflow, edge support, and support for heavier sleepers, and costs a bit more. It’s new and has far fewer reviews so far. The Casper Original adds more comfort layers and zoned support for a big jump in price.

Who Should Buy It, and Who Should Skip It

Buy it if you’re a back or combination sleeper of average weight, want a responsive foam feel with good motion isolation, and value a name brand, a 100-night trial, and a 10-year warranty at a moderate price.

Skip it if you weigh more than about 230 pounds, sleep only on your side with broad shoulders or hips, sleep very hot, or need firm edges. A thicker hybrid is a better fit.

Final Verdict

The Casper Element does the basics well: a responsive, medium foam feel, good motion isolation, and a cooler top layer than traditional memory foam, backed by a 100-night trial and a 10-year warranty. It’s a sensible choice for average-weight back and combination sleepers and couples on a budget. Heavier sleepers, strict side sleepers, and hot sleepers should step up to a hybrid.
