Casper vs Serta 2026: Which Mattress Should You Buy?

Choosing between Casper and Serta comes down to feel, construction and how each brand handles the buying experience. Casper sells foam and hybrid mattresses with published prices, a 100-night trial and a 10-year limited warranty. Serta sells innerspring, hybrid and foam mattresses across several collections, with prices starting at $219 for the Serta Five Star. Both are established names, but they are built differently and priced differently.

If neither feels right, the Saatva Classic is a strong alternative: an innerspring mattress with three comfort levels, a 365-night home trial and a lifetime warranty. We will come back to it at the end.

Which mattress should you buy, Casper or Serta?

The Casper vs Serta choice favors Casper for shoppers who want a clear, published price and a simple foam or hybrid lineup. Casper lists The One foam mattress at $699 and the Dream hybrid at $1,215, with a 100-night trial and a 10-year limited warranty.

The short version: pick Casper if you want a medium-firm foam feel with a published price and a stated trial. Pick Serta if you want an innerspring or hybrid with zoned lower back support and a lower entry price. If a 100-night trial feels short, the Saatva Classic carries a 365-night home trial.

Who is Casper best for, and who is Serta best for?

Casper suits sleepers who want a foam or hybrid mattress with a medium to medium-firm feel and a published price. Serta suits shoppers who want an innerspring or hybrid with zoned support, including the Serta Five Star with 3 zones for lower back support and the Perfect Sleeper with up to 5 support zones. Serta’s entry price of $219 undercuts Casper’s $699 starting price for The One.

• Shoppers who want a published price before they click, with The One at $699 and Dream at $1,215
• Side and back sleepers who prefer a medium-firm foam feel, as described for The One
• Hot sleepers who want a cooling option, since Casper lists Snow as a memory foam bed that sleeps cool with QuickCool cover technology
• Buyers who want a stated 100-night trial and 10-year limited warranty in writing
• Shoppers who want optional white glove delivery and free, no-contact delivery

• Shoppers who want a lower entry price, starting at $219 for the Serta Five Star
• Buyers who want zoned lower back support, offered across the Five Star, Classic and Perfect Sleeper collections
• People who want an innerspring build rather than foam, since Serta lists innerspring, hybrid and foam types
• Shoppers who want a full size range from Twin through Cal King, with Split Head Queen and Split Head King on select models
• Buyers who prefer a long-established brand with collections at several price tiers

If you want a foam build specifically, our best memory foam mattress picks for 2026 cover more options in that category.

How do Casper and Serta compare on feel and construction?

Casper states its feels directly: The One is medium-firm, Dream is medium, Cloud One is medium-soft, and Snow is medium conforming. Serta describes its collections by construction rather than a single feel scale, listing firmness filters of Firm, Medium, Plush and Extra Firm across its range. Casper gives you a named feel on each product; Serta gives you a construction type and a firmness filter.

Casper’s lineup splits into foam and hybrid builds. The One uses three layers of cradling foam for a responsive yet supportive medium-firm feel. Dream pairs responsive springs with ergonomic support zones. Snow combines conforming memory foam with encased coils. Serta’s collections work the same way: the Five Star uses an individually-wrapped coil system with 3 zones, the Perfect Sleeper offers up to 5 support zones with pressure-relieving memory foams, and the iComfort line offers 5 support zones with cooling foams.

Which brand is better for hot sleepers?

Casper is the clearer choice for hot sleepers between the two, because Casper states a cooling purpose on its products: Snow is described as a memory foam bed that sleeps cool, and the QuickCool cover uses cool-to-the-touch fibers. Serta mentions cooling foams and cool-to-touch fabrics in the iComfort collection and cooling layers as upgrades on Perfect Sleeper, but gives no duration claim. Neither brand’s cooling claim is independently verified here, so treat both as manufacturer descriptions.

Casper’s Snow page states the mattress attacks overheating for 12+ hours, which is a brand claim about its own product. Serta’s cooling language appears across iComfort and as upgrade options rather than on every model. If cooling is your main concern, our best cooling mattress roundup for 2026 lists other options worth comparing.

What does each mattress cost?

Casper publishes prices on its mattress page: The One is $699, Dream is $1,215, Snow is $1,590, Cloud One is $899, Dream Max is $2,040, and Snow Max is $2,525. Serta’s figures are starting prices for a collection, not a specific size, so they are not directly comparable to Casper’s listed prices without checking the size you need.

Both brands run frequent sales, so check today’s price before you buy. Casper’s page shows savings against a comparison value, and Serta’s collection page shows starting prices that may shift by size and model.

How do the trial periods and warranties compare?

Casper states a 100-night trial and a 10-year limited warranty, with free no-contact delivery, optional white glove delivery, free returns, and quick financing options.

The gap matters if you want time to decide. Casper gives you 100 nights and 10 years of limited warranty coverage. The Saatva Classic, as an alternative, carries a 365-night home trial and a lifetime warranty, both longer than Casper’s stated terms.

For a longer look at how Saatva’s trial and warranty work in practice, see our Saatva Classic review.

Who should NOT buy Casper or Serta?

Skip Casper if you want an innerspring build, since Casper’s lineup here is foam and hybrid only, with no innerspring option listed.

Also skip both if you want a split head size in every model: Casper lists Split King, while Serta lists Split Head Queen and Split Head King only on select models. If firmness is your main filter, our best firm mattress picks for 2026 collect the firmer options in one place.

What is the Saatva alternative to Casper and Serta?

The Saatva Classic is a strong alternative if you want an innerspring mattress with more trial time and a longer warranty than Casper’s stated terms. Saatva lists three comfort levels: Plush Soft at 3/10 on Saatva’s own scale where 1 is softest and 10 firmest, Luxury Firm at 5-7/10, and Firm at 8/10. The Luxury Firm level is described as a medium feel that balances cushioning and uplifting support, similar in intent to Casper’s medium-firm The One.

Saatva’s construction includes a 3-inch Euro pillow top, a dual-coil design with over 1,000 recycled carbon steel coils in full size and up, and patented Lumbar Zone technology for spinal alignment. It comes in two heights, 11.5 inches and 14.5 inches, and pairs with a foundation, box spring, bunkie board, platform frame or adjustable base. Delivery includes in-room setup and removal of your old mattress at no extra cost.

Where Saatva pulls ahead of both brands here is the trial and warranty: 365 nights versus Casper’s 100 nights, and a lifetime warranty versus Casper’s 10-year limited warranty. Saatva’s foams are CertiPUR-US certified and its mattresses are GREENGUARD Gold certified, and the brand is endorsed by the American Chiropractic Association.

For shoppers comparing hybrid builds specifically, our best hybrid mattress roundup for 2026 places Saatva alongside other coil-and-foam options.

Frequently asked questions

Is Casper firmer than Serta?

Casper states specific feels on its products: The One is medium-firm, Dream is medium, and Cloud One is medium-soft. Serta does not assign a feel to each model on the collection page; instead it offers firmness filters of Firm, Medium, Plush and Extra Firm across its range. Whether one brand is firmer than the other depends on the specific model you choose from either lineup.

Does Serta offer a trial period like Casper’s 100 nights?

Casper states a 100-night trial on its mattress page. If a long trial matters to you, the Saatva Classic carries a 365-night home trial.

Which brand has more construction options?

Serta lists three construction types: foam, hybrid and innerspring, across collections including Five Star, Classic, Perfect Sleeper, iSeries NXG, iComfort and iComfortPro. Casper lists two: foam and hybrid. Serta’s range is broader on construction, while Casper’s is narrower with a named feel on each product.

Can I get a cooling mattress from either brand?

Casper offers the Snow and Snow Max, described as memory foam beds that sleep cool, with QuickCool cover technology using cool-to-the-touch fibers. Serta offers cooling foams and cool-to-touch fabrics in the iComfort collection, with cooling layer upgrades on Perfect Sleeper. Both descriptions are manufacturer claims about their own products.

Do both brands offer white glove delivery?

Casper lists optional white glove delivery alongside free, no-contact delivery. The Saatva Classic includes free white glove delivery with in-room setup and old mattress removal as standard.

Verdict: Casper wins this comparison for shoppers who want a published price, a named feel and a stated trial on every product. Serta wins for shoppers who want a lower entry price, an innerspring build and zoned lower back support. Neither brand’s trial or warranty terms should be assumed beyond what each page states. If you want more time to decide and a longer warranty than Casper’s stated 100 nights and 10 years, the Saatva Classic is the alternative worth checking.
