Casper vs Puffy (2026): Mattress Models Compared

Choosing between Casper and Puffy starts with the model, not just the brand. Casper The One is an 11-inch all-foam mattress described by Casper as medium-firm; Puffy describes the 12-inch Lux Hybrid as medium-plush, with foam and wrapped coils. Both brands sell other models with different feels and constructions.

Our starting point: Consider The One if you want a medium-firm foam bed and the Lux Hybrid if you prefer a plusher surface with coils. Body weight, sleep position and personal preference affect the fit. This is a comparison of the brands’ published current specifications and buying terms; it is not a newly conducted head-to-head test.

Sources checked November 1, 2026: Casper The One, Puffy Lux Hybrid, Casper trial and Puffy guarantee. Specifications, offers and policies can change, and retailer terms can differ.

Which mattress should you consider?

Choose Casper The One as a starting point if…

• You prefer the simpler construction of an all-foam mattress and a medium-firm feel.
• You sleep on your back or change positions and want to try a firmer-feeling option. Stomach sleepers should check that their hips feel supported in their usual position.
• You want to compare an 11-inch foam model with softer Casper options such as Cloud One.

Consider Puffy Lux Hybrid if…

• You prefer a plusher surface and want to explore a foam-and-coil design.
• You sleep on your side and want to check cushioning at your shoulder and hip.
• A longer direct-brand trial matters to you. Read the return conditions before ordering.

Neither choice is guaranteed to feel right for a particular sleep position or body weight. Try the exact model where possible; for persistent pain or a medical concern, consult a qualified clinician.

Construction and lineup differences

Casper The One and other Casper models

Casper lists The One as an 11-inch all-foam mattress. Cloud One is another 11-inch foam model with a plusher feel, while Dream and Snow are hybrid models. The Casper Original, Nova and Wave discussed in older reviews are legacy models; their construction and observations should not be assumed to describe The One. See our Casper model guide and The One review for model-specific context.

Puffy Lux Hybrid and other Puffy models

Puffy lists the Lux as a 12-inch hybrid with foam and wrapped coils, described as medium-plush. Its Cloud is a 10-inch all-foam model; Royal is a taller hybrid. See the Puffy model comparison, our Puffy lineup guide and Puffy Lux Hybrid review. Check the exact model and specifications at checkout, since designs can change.

Feel, cooling and motion transfer

Feel and pressure: The brands describe The One as medium-firm and Lux Hybrid as medium-plush. Those labels are useful starting points, not equivalent standardized measurements. Try each in your usual position, paying attention to shoulder and hip comfort and whether you can move easily.

Cooling: Puffy describes cooling foam and airflow around the Lux’s coils; Casper describes The One’s foam as breathable. These design descriptions do not establish which bed sleeps cooler for you. Sheets, protectors, room temperature and individual heat sensitivity matter too.

Couples: Both foam layers and individually wrapped coils can affect motion transfer. If possible, have one partner change position while the other lies still, and test the edge if you sit or sleep near it. We do not have a current, verified head-to-head result for these exact builds here.

Earlier comparison notes

In an older version of this guide, Yawnder described the Casper Original as more responsive and rated it 7/10 for firmness; it rated a Puffy Lux 5.5/10 and described a deeper contouring feel. Those observations refer to the older comparison, whose exact Puffy build and test date are not established here. They should not be treated as scores for the current The One or Lux Hybrid.

Price, delivery and warranty

Compare the same mattress size at the final checkout price, including delivery, setup, foundation and any return charges. Promotional prices change; a longer warranty does not prove that a mattress will last longer or cover normal comfort changes.

For direct purchases, Casper advertises a 100-night trial, a 30-night adjustment period and free eligible mattress returns. Puffy advertises a 365-night trial and free mattress returns; confirm the exact eligibility and timing when ordering. Casper offers a 10-year limited mattress warranty and Puffy a limited lifetime mattress warranty for covered defects. Both have exclusions. Policies can differ when you buy from Yawnder or another retailer, so check that seller’s written terms.

Frequently asked questions

Is Casper or Puffy better for side sleepers?

Start with the individual model. Puffy describes Lux Hybrid as medium-plush, while Casper offers the softer Cloud One as well as the medium-firm The One. The best fit depends on your weight and how your shoulder and hip feel.

Which is firmer, Casper The One or Puffy Lux Hybrid?

Casper describes The One as medium-firm, while Puffy describes Lux Hybrid as medium-plush. These are the brands’ descriptions, not a new Yawnder head-to-head firmness test.

Which sleeps cooler?

There is not enough comparable evidence here to name a winner. Compare each model’s construction and your bedding and room temperature, then use the applicable sleep trial.

Can I try these mattresses in a store?

Availability varies by model and retailer. Contact the Yawnder showroom before visiting to check whether a particular model is on the floor.
