Our next engagement, Casper Vs. Leesa, contrasts two well-known mattresses designed by bed-in-a-box veterans in business since 2014. Casper is constantly innovating based on customer feedback, and Leesa is committed to social impact, delivering mattresses to those in need and planting trees.

Both of these 10-inch, all-foam beds were designed to have a universal appeal, which was formulated to comfort and support a large variety of individuals and their preferences. But which is the best for you?

Comparing Construction (Materials & Quality)

Casper Construction

Casper’s flagship all-foam mattress is compressed and delivered to your home packed into a box. Depending on where you live and when you order, In-Home delivery, a service that will unpack and place your mattress, may be available.

The polyester cover can be removed and spot cleaned. It is stretched to fit the 11-inch height and three layers.

• The top layer’s  thick foam designed to be breathable for temperature control and quick-responding for easy repositioning.
• The second layer transitions with a layer of poly foam that is tailored to build a firmer center and provide additional support beneath your hips. This Zoned Support™ offers tailored firmness that boosts alignment for your spine.
• The third layer forms the base with denser poly foam formulated to be durably provide spine alignment.

Leesa Construction

All-foam Leesa is rolled into a box and mailed, but the company also has made white glove delivery available in selected areas. It is also one of few brands that can be tested in stores, following a partnership between the company, Pottery Barn, and West Elm.

The cover, which bears the company’s four-stripe design, is made from a blend of polyester, viscose, and polyamides that can be zipped off for spot cleaning. The mattress is 10 inches in height and is made up of three layers.

• The top layer is made from a 2-inch quick-responding foam. This layer has pinholes to help temperature-regulating air flow through the surface while cradling your body.
• The second layer is built with memory materials and stands 2 inches thick. This adds contouring at a deeper level and traps body heat away from the surface, helping you stay cool.
• The base layer’s poly foam is denser than the previous two layers, which lends the bed a 6-inch foundation and provides firmness necessary to the sleeper’s spine.

Comparing Firmness (Support & Feel)

On our scale to 10 when 10’s the firmest, we score the Casper at a 6 and the Leesa at a 5.5. Though both mattresses are within the boundaries of what we’d consider Medium to Medium-Firm, the Leesa may feel just a touch softer (Not sure what that means? Check out our Firmness Guide for more info).

Both brands were built to hit the sweet spot on feel with a blend of support and comfort that most people prefer in most positions. Also, the construction both follows a similar pattern: A quick-responding and breathable material, followed with denser supportive materials.

Casper’s targeted spine alignment with its Zoned Support™ in the third layer amps up the bed’s ability to hold most bodies in a neutral position, especially for sleepers who carry extra weight around their middles because of the extra firmness placed in the center. Exclusive stomach sleepers, in particular, should love this new feature.

Leesa’s slightly softer comfort layers on top and increased thickness of comfort materials overall, give it a slight edge with pressure relief. Side sleepers tend to need more pressure relief around their shoulders and hips because more weight is pressing down on a smaller surface area. Exclusive side sleepers should appreciate the additional softness of Leesa, though back and stomach sleepers should still feel well supported.

Though each offers a slight edge in certain positions, both should perform with a versatility that should work well with most sleeping positions and for an array of body shapes.

Though Casper does not suggest a weight limit, Leesa recommends a maximum weight of 300 pounds for each individual sleeping on the mattress. Those with significant weight concerns should also note that both companies offer upgraded models, Casper Wave and the Sapira, that include additional enhanced support materials.

Comparing Sinkage and Bounce

Casper contains 3 inches of softer comfort layers to Leesa’s 4, so you might find Leesa’s cradle to be a touch deeper than Casper’s gentle cradle. Casper’s firmer layers should have slightly more bounce as well, which pairs with the firm base and quick-response time to help make repositioning simple to manage. Though Leesa’s bounce is minimal, the quick-responding latex-like material on the top should not pose any significant difficulty for active sleepers looking to move around at night.

Comparing Motion Transfer

Beds that incorporate memory materials do a great job in this category, so you shouldn’t wake up in the middle of the night feeling your partner tossing and turning in either of these mattresses. Even though Casper has slightly more bounce, both mattresses perform roughly the same.

---

Comparing Edge Support

Beds that have been compressed in boxes typically do not have defined edges, but both brands exceed expectation in this category. You may notice some slight compression when you sit on the edges, but sleeping along the side of both beds should feel secure.

Not everyone thinks about edge support, but couples who share their sleep space can increase their surface space by shopping for consistent edge-to-edge consistency.
