by Puffy is the pick here, and it earns the top spot on its own merits: a 365-night trial, lifetime warranty, and a plush all-foam build that works well for side sleepers. Casper One is a solid, cheaper alternative with better zoned support, but neither is as capable as a coil hybrid. For back sleepers, hot sleepers, or anyone over 200 lb, a hybrid like the Puffy Lux Hybrid or Saatva Classic is worth the upgrade.
Puffy Original
8.4/10
- 365-night trial, the longest in this price range
- Lifetime warranty (vs Casper's 10 years)
- Plush Cooling Cloud foam layer works well for side sleepers and lighter sleepers
- CertiPUR-US certified, no fiberglass in the cover
- All-foam runs warmer than a hybrid; not the right pick for hot sleepers
- Uniform foam layers offer less lumbar zoning than Casper's design
- Weak edge support, typical of all-foam construction
For side sleepers who want a soft, pressure-relieving surface and the longest trial window in this category, Puffy Original is the clear call. The lifetime warranty and 365-night trial give you more post-purchase protection than Casper at a comparable price.
Puffy vs Casper: head-to-head
Both Puffy Original and Casper One are all-foam, box-delivery mattresses aimed at the mid-range market. They share the same basic weaknesses, no coils means moderate cooling and weak edge support. Where they differ is in feel, zoning, trial length, and warranty.

| Type | All-foam | All-foam |
| Height | 10 inches | 11 inches |
| Firmness | Medium 5/10 | Medium-firm 6/10 |
| Queen price (sale) | ~$1,249 | ~$1,095 |
| Trial | 365 nights | 100 nights |
| Warranty | Lifetime | 10 years |
| Cooling | Cooling Cloud foam (average) | AirScape perforated foam (slightly better) |
| Zoned support | Uniform layers | Yes, firmer center zone |
| Edge support | Weak | Weak |
| Fiberglass | No | No |
Construction and feel
Puffy Original
The Puffy Original uses three foam layers: a proprietary Cooling Cloud comfort layer on top, a transition foam in the middle, and a dense base for support. The result is a slower, more cradling feel than Casper. Press your hand in and it takes a moment to rebound. Side sleepers who want their shoulders and hips absorbed rather than pushed back tend to prefer this. Back sleepers and anyone over 200 lb may find the hips sink a touch too far, breaking spinal alignment.
The knit cover is soft and removable. Setup is standard box delivery: cut the plastic, the mattress expands within a few hours, and you can sleep on it the same night.
Casper One
Casper renamed their Original as the "One," but the engineering that matters is the zoned support layer. The center section, where your hips and lower back land, uses firmer foam than the shoulder zones. You can feel this when you lie down: hips stay higher, spine stays more neutral. For back sleepers and combination sleepers, this is a meaningful structural advantage over Puffy's uniform layers.
Casper's top foam is also slightly more responsive, so changing positions at night requires less effort. If you switch between back and side frequently, that matters.
Who wins by use case
Side sleepers: Puffy. The softer surface absorbs shoulder and hip pressure more effectively. Lighter sleepers (under 150 lb) especially benefit from the plush top layer.
Back sleepers: Casper One, narrowly. Its zoned center keeps the lumbar from sinking. On Puffy, heavier back sleepers may notice their hips dipping slightly low over time.
Stomach sleepers: Neither is ideal. Both are soft enough to let the hips sink and arch the lower back. Stomach sleepers over 130 lb need a firmer build than either of these provides.
Combination sleepers: Casper, for its faster foam response. The Puffy's slower rebound can create friction when rolling over mid-night.
Couples: Puffy has a slight edge on motion isolation. Its denser, slower foam absorbs movement a bit better.
Hot sleepers: Neither is a good fit, but Casper's open-cell AirScape foam runs slightly cooler than Puffy's Cooling Cloud. If heat is a serious problem, step up to a hybrid.
Heavier sleepers (over 230 lb): Skip both. All-foam beds compress too much at higher weights, degrading edge support and lumbar alignment. A coil-based mattress handles the load more durably.
Durability and long-term performance
All-foam mattresses break down faster than coil hybrids. Without springs to hold structure, you rely entirely on foam density. Both Puffy and Casper are honest mid-range builds: expect 7 to 10 years of full performance before the foam softens noticeably in the hip zone.
Casper's zoned construction spreads wear more evenly, which gives it a slight edge in long-term shape retention. Puffy's lifetime warranty sounds like it solves this, but the practical threshold for a claim is visible sagging beyond 1.5 inches, which typically does not appear before you would want to replace the mattress anyway. Treat both warranties as effective 10-year coverage for real-world purposes.
Price and value
| Puffy Original | Casper One | |
|---|---|---|
| Queen (sale) | ~$1,249 | ~$1,095 |
| MSRP | ~$2,399 | ~$1,695 |
| Trial | 365 nights | 100 nights |
| Warranty | Lifetime | 10 years |
The price gap is smaller than Puffy's inflated MSRP makes it look. At sale prices, Casper is about $150 cheaper. For that extra $150, Puffy gives you a much longer trial (365 vs 100 nights) and a lifetime warranty. If you tend to take time deciding whether a mattress is right for you, that 365-night window is genuinely useful.
On pure value-per-dollar, Casper wins. The zoned support and lower price are hard to argue against. But Puffy's terms give you more post-purchase flexibility, and that has real-world worth.
The hybrid step-up
Both mattresses share a ceiling: all-foam construction. If you want better cooling, real edge support, or a mattress that holds up past year 7 at a heavier weight, you need coils. The Puffy Lux Hybrid addresses all of this: a coil layer under a foam comfort system, better airflow, stronger perimeter support, and the same 365-night trial and lifetime warranty as the Original.
Saatva Classic is the other natural comparison at this step-up tier: a coil-on-coil hybrid with white-glove delivery and a 365-night trial. Both are worth pricing out if your budget can reach $1,500 or above.
The $250 question had a $0 answer: neither, if you need coils
Puffy earned the win here — the year-long trial and plush side-sleeper feel are real advantages over Casper’s zoned but shorter-trialed build. Yet this page kept repeating one honest caveat: back sleepers, hot sleepers and anyone carrying more weight were pointed past both, toward a coil hybrid. The $250 gap between two foams stops mattering the moment you’re in that group.
The hybrid this page named is the Saatva Classic: coil-on-coil support that handles heat and heavier bodies structurally, plush euro top, white-glove delivery. If any of the step-up warnings above described you, skip the foam question entirely and check the Classic’s price today.
Frequently asked questions
Is Puffy worth the extra cost over Casper One?
At sale prices, the gap is roughly $150. What you gain with Puffy is a softer feel, a 365-night trial versus Casper's 100 nights, and a lifetime warranty. If those terms matter to you, Puffy is worth it. If you want zoned lumbar support and a more responsive feel, Casper is the better call for the money.
Do Puffy and Casper sleep hot?
Both run warmer than a hybrid or innerspring, because all-foam traps heat more than a coil system with airflow gaps. Casper's AirScape perforated foam is slightly cooler, but the difference is marginal. Neither is the right mattress if you sweat significantly during sleep.
Which is better for back pain?
Casper One, narrowly, because its zoned support keeps the lumbar region from sinking as far. For more serious back pain, a coil hybrid with a dedicated lumbar zone (Puffy Lux Hybrid, Saatva Classic) outperforms both all-foam options.
Can I try either of them before buying?
Both are online-only. Puffy offers a 365-night home trial, Casper offers 100 nights. Neither requires you to return within 30 days, though Puffy asks for a minimum 30-night break-in before initiating a return. Returns are free on both sides.
What about Puffy Lux vs Casper Nova Hybrid?
Both are significant step-ups from the base models. Puffy Lux Hybrid adds coils for better cooling, edge support, and durability. Casper Nova Hybrid adds zoned coil support for side sleepers with hip or shoulder pressure. At comparable prices, Puffy Lux Hybrid's 365-night trial and lifetime warranty tip the value calculation in its favor.
