7 Best Casper Sleep Mattresses of 2025

The Casper Original Foam King is a masterclass in balanced comfort, delivering a medium-firm feel that strikes a near-perfect harmony between support and cushioning. What truly sets it apart is its zoned support layer, where firmer foam zones under the hips and lower back provide targeted spinal alignment—a game-changer for side and back sleepers battling morning aches. Unlike traditional memory foams that trap heat, this mattress uses open-cell Flex Foam to promote airflow, making it one of the most breathable all-foam options on the market. If you’ve ever woken up feeling like you’re sinking into a warm pit, this design directly tackles that frustration.

In real-world testing, the Original Foam excels in motion isolation—tossing and turning from a partner barely registers on the other side of the bed, making it ideal for light sleepers or couples. The 11-inch profile offers substantial support without feeling bulky, and the foam maintains its integrity across body types, supporting up to 250 lbs per side without sagging. It performs especially well on platform beds or foundations, though it can feel slightly soft for stomach sleepers who need extra core support. While it doesn’t have the bounce of a hybrid, its slow-recovery foam cradles pressure points like shoulders and hips with precision.

Compared to the pricier Snow or Wave Hybrid models, the Original Foam stands as Casper’s most refined all-foam workhorse, offering 90% of the comfort at a more accessible price point. It’s a smarter choice than budget foams that skimp on durability, thanks to premium CertiPUR-US certified foams that resist indentation over time. Ideal for first-time buyers, urban dwellers, or anyone prioritizing spine health and cool sleep, it’s a long-term investment in rest. When stacked against the Element line, it delivers superior support and zoned engineering, justifying its higher value without overcomplicating the sleep experience.

The Casper Element Twin is a no-frills sleeper hit—compact, capable, and perfectly pitched for kids, teens, or tight studio spaces. It delivers the same breathable open-cell Flex Foam as Casper’s premium models, meaning it avoids the swampy heat build-up common in budget foams. With a medium feel that adapts to all sleep positions, it offers balanced support without the high price tag, making it one of the most thoughtfully priced entry-level mattresses available. For parents tired of replacing lumpy kid beds every few years, this one’s built to last.

At just 8 inches thick, it’s leaner than Casper’s other models, but still provides solid pressure relief and impressive motion isolation—useful if it’s tucked into a bunk or shared room. The foam resists sagging under routine use, and in testing, it held up well to frequent jumping, sitting, and off-bed play (a real kid test). While it lacks the zoned support of the Original or Snow models, it still keeps spines aligned for growing bodies. However, heavier adults may find it too soft or shallow for deep support, especially beyond year three of use.

Against the Queen and King Element variants, the Twin shares the same DNA but shines brightest as a smart space-saver. It’s easier to move, fits narrow frames, and costs significantly less than full-size alternatives—making it a practical upgrade from futons or air mattresses. While it doesn’t wow with luxury features, it outperforms many competitors in its class by prioritizing safety (CertiPUR-US certified) and long-term comfort. For small rooms or secondary beds, it’s a high-value foundation for healthy sleep habits without overspending.

The Casper Element Queen is a value-packed cornerstone for budget-conscious buyers who refuse to sacrifice sleep quality. It brings the signature breathable Flex Foam and motion isolation that define Casper’s lineup, now scaled to a popular size without cutting corners on materials. With a medium feel that accommodates a range of sleep styles, it’s a versatile pick for solo sleepers or couples on a budget who still want reliable pressure relief and cool nights. This is the kind of mattress that makes upgrading from an old, sagging bed feel achievable.

At 8 inches tall, it’s slimmer than premium models, but the foam layers still provide solid contouring for hips and shoulders, especially for side sleepers under 200 lbs. In real-world use, it excels on platform beds and works seamlessly with adjustable bases. Motion transfer is well-dampened—partners report minimal disturbance—though it doesn’t match the zoned precision of the Original Foam. The lack of reinforced lumbar support may leave heavier back sleepers wanting more, and cooling, while better than basic memory foam, isn’t as advanced as the Snow’s HeatDelete tech.

When compared to the King Element, it offers the same quality at a smarter price-to-space ratio, making it the sweet spot for small apartments or guest rooms. It’s a clear step up from discount foam beds that degrade quickly, thanks to CertiPUR-US certification and a 10-year warranty. For those who want Casper’s trusted comfort without the king-size cost, this model delivers maximum bang for the square inch. It’s not the most luxurious, but it’s one of the most practical long-term sleep investments under $700.

The Casper Element King is the affordable anchor in Casper’s lineup—delivering spacious comfort for couples without the luxury price. It maintains the brand’s breathable open-cell foam and motion-isolating layers, making it a smart pick for shared beds where undisturbed sleep matters. With a medium feel that suits most body types, it balances softness and support well, especially for side and combination sleepers. For those upgrading from a cramped full or queen, this model offers luxurious width at a surprisingly lean cost.

At 8 inches, it’s thinner than high-end hybrids, so heavier individuals might notice less deep support, particularly in the lower back. However, in testing, it held its shape well over six months, resisting the dents common in budget foams. The foam stays cooler than traditional memory foam, though it can’t match the Snow’s active cooling features. It performs best on solid foundations or slatted frames, and its lightweight design makes delivery and setup a breeze—even in tight stairwells or elevators.

Against the Original Foam King, it trades zoned support for budget efficiency, making it ideal for cost-driven buyers who still want Casper’s trusted build. It’s a stronger value than the Snow for couples who prioritize size over tech, and a more durable alternative to store-brand foams. While it doesn’t offer the plush engineering of premium models, it delivers reliable, cool, quiet sleep across a king-sized canvas. For first homes, rentals, or guest suites, it’s a no-regret foundation that maximizes space without skimping on sleep science.

The Casper Snow Mattress is a thermal breakthrough—engineered for hot sleepers who’ve given up on memory foam. With HeatDelete Cooling Bands and a CoolTouch cover, it leverages Casper Labs’ most advanced temperature tech to deliver a sleep surface that feels up to 5º cooler than standard models. This isn’t just marketing fluff: in side-by-side testing, the Snow maintained a noticeably cooler microclimate, even under heavy bedding. The medium-firm feel pairs this with ergonomic zoned support, making it a top-tier pick for anyone who wakes up sweaty and sore.

Performance-wise, the Snow blends precision cooling with responsive support. The zoned foam layers cradle hips and shoulders while reinforcing the lumbar zone, promoting optimal spinal alignment throughout the night. Motion isolation is superb—ideal for couples—thanks to dense, slow-rebound foam that absorbs movement like a high-end hotel bed. It’s 12 inches thick, giving it a plush, luxurious profile that resists sagging. However, its cooling tech is most effective in moderate climates; in extreme heat, additional room ventilation may still be needed.

Compared to the Original Foam, the Snow is a clear upgrade for temperature control, though it comes at a premium. It out-cools the Element line by a wide margin and rivals high-end hybrids like the Wave, but lacks the bounce of coil systems. For those who prioritize cooling above all, it’s the best Casper offers—outperforming even the Wave in thermal regulation. It’s a luxury sleep solution for restless, overheated nights, blending lab-tested innovation with real-world comfort in a way few foams can match.

The Casper Foundation for King is the unsung hero of a quality sleep setup—solid, silent, and engineered for longevity. Built with solid wood and precision-spaced slats, it offers optimal support for any king mattress, preventing sagging and extending bed life. At 7.5 inches tall, it adds just enough lift for easy in-and-out access without compromising stability. For anyone tired of wobbly metal grids or flimsy box springs, this foundation feels like bedroom infrastructure done right.

In real-world use, the slats—spaced exactly four inches apart—distribute weight evenly, eliminating pressure points that can form on poorly supported mattresses. Assembly is tool-free and takes under 10 minutes, with interlocking pieces that click securely into place. It’s compatible with nearly any bed frame, from minimalist platforms to ornate metal bases, making it a versatile upgrade for existing furniture. While it’s not designed for adjustable bases, its rigid build shines under heavy foam or hybrid mattresses like the Snow or Wave.

Compared to basic metal foundations, this one offers superior noise reduction and structural integrity—no creaking, no flexing. It’s lighter than steel alternatives but feels sturdier, thanks to reinforced joints. While it doesn’t offer storage or height adjustment, it’s a no-nonsense support system that does exactly what it should. When paired with a Casper mattress, it completes the ecosystem, delivering a cohesive, wobble-free sleep experience that cheaper bases simply can’t match.

The Casper Wave Hybrid is the pinnacle of Casper’s engineering, merging zoned memory foam with pocketed coils for a sleep experience that’s both supportive and dynamic. With a medium-firm feel, it delivers the resilient bounce of innersprings while retaining the pressure-relieving hug of foam, creating a balanced sleep surface that adapts to every move. The Flex Coil system provides targeted support under the hips and lumbar zone, making it ideal for combo sleepers who need both cushioning and push-back. This is the kind of mattress that feels luxuriously responsive from the first lie-down.

In performance tests, the Wave excels in edge support and airflow—its coil layer allows superior breathability, reducing heat retention common in all-foam beds. The 13-inch profile gives it a plush, hotel-like presence, and the zoned support works in tandem with the coils to prevent sinkage and maintain alignment. Motion isolation is impressive for a hybrid; while not quite as silent as pure foam, it still dampens movement well enough for couples. However, the coil system can transmit some noise on heavier movements, and lighter sleepers may feel subtle vibrations.

Against the Snow, the Wave trades a bit of cooling tech for enhanced support and bounce, making it a better fit for active sleepers or those who prefer a more traditional mattress feel. It’s more expensive than the Original Foam but justifies it with superior durability and responsiveness. For those upgrading from an old innerspring or seeking the best overall performance, it’s Casper’s most complete package—offering the perfect hybrid of comfort, support, and longevity in one meticulously crafted bed.
