Puffy Mattress Review Highlights

  • Cooling: Puffy designed their Cooling Cloud layer to regulate the temperature of your sleeping surface. It features cooling gel that is cool-on-contact and prevents heat from staying trapped in the foam layers. It’s also high in breathability, garnering a 8/10 score for cooling in our lab assessment.
  • Pressure Relief: Puffy is one of our top rated memory foam mattresses in part because of its excellent pressure relieving properties. The Firm Core support layer cradles pressure points by contouring around shoulders and hips. This makes it a great choice for side sleepers who need extra cushion. 
  • Motion Isolation: The best mattresses for couples absorb motion from movement. The Puffy scored 9.25/10 on motion transfer, meaning you get to sleep through your partner’s tossing and turning. 
  • Lifetime Warranty: Your new bed from Puffy is protected for life. In other words, you pay one price for your original mattress and never need to buy another full-priced mattress again. We’re not sure it gets much better than that!
  • Stain-Resistant Cover: The top layer of your Puffy bed repels spills and cleans up quickly. It’s also zipper-removable, so you can deep clean dirt and germs that accumulate over time. 
  • Puffy offers two other luxury beds: the Puffy Royal and the Puffy Lux mattress.

Casper Mattress Review Highlights

  • Recommended for Side Sleepers: We included the Casper mattress in our list of top-rated beds for side sleepers because it scored high on spinal alignment and pressure relief. Both are vital for side sleepers to wake up without pain and stiffness in their shoulders and lower back.
  • Zoned Support™: Casper designed their comfort layer to uniquely support each region of your body. Shoulders, knees, and ankles are cushioned with softer foam while hips and the lower back region are supported with firmer foam.
  • Breathable: Memory foam has a reputation of absorbing all your body heat throughout the night, making it too hot to rest well. Casper’s top layer is perforated, which improves airflow, keeping you cooler while you sleep. 
  • Responsiveness: The Casper scored a perfect 10/10 on our responsiveness test. It quickly conforms to changes in your position, so you can move without having to wait for your mattress to adjust. 
  • Universal Comfort: Casper is 7/10 on the firmness scale, which suits most sleep positions. It’s medium-firm feel is supportive enough for back sleepers and contouring enough for side and stomach sleepers
  • Memory foam isn’t the only type of mattress Casper makes. Check out the Casper Hybrid mattress, Casper Nova Hybrid, and the Casper Wave Hybrid.

Verdict: Which Is the Best Mattress?

Casper provides better pressure relief and spinal for side sleepers. Puffy is better for couples who need motion isolation. Puffy is cooler, making it the preferred option for hot sleepers. Casper is the more budget-friendly option. Puffy’s lifetime warranty is the better choice for those concerned about protection against defects.

Read on for a more thorough discussion of which mattress is best for each of these categories.

Sleeping Position

Every sleep position needs a mattress that supports spinal alignment, and Casper scores higher in this category. Casper also scores higher for pressure relief, which means it will be more comfortable for side sleepers

A highly responsive mattress is important for combination sleepers who change position throughout the night. Again, Casper takes the cake, this time with a perfect 10/10.

Sleep Environment

If you’re sleeping with someone, you’ll want to think about motion isolation, which is a mattress’s ability to absorb movement. The Puffy mattress scored noticeably higher in this category, although neither scored particularly low. 

Mattress temperature is also important, particularly with foam beds. Puffy scored a full point higher than Casper for cooling, so it’s the better choice for those who sleep hot. 


Casper is the more affordable option with prices between $55-$200 cheaper than Puffy. The Full size is the same price for both brands. Neither mattress brand is prohibitively expensive, and both offer financing options to shoppers (Casper through Affirm and Puffy through Klarna).

Consumer Experience

This is one area where these mattresses differ significantly. Puffy offers their mattress owners a lifetime warranty, whereas Casper offers only a 10-year limited warranty. The typical mattress remains effective for at least 10 years, so both warranties cover the mattress’s lifespan. 

Both Puffy and Leesa provide a 3+ month trial period. Puffy’s is a single day longer than Casper’s at 101 nights compared to 100-nights.
