Comparing Construction: Leesa vs Casper
Leesa’s Sapira Hybrid Mattress has six layers and is 11 inches thick, while the Casper Dream has four layers and is 12 inches thick. While both mattresses combine multiple foams and individually wrapped springs, they have clear differences in construction.
Foams
Casper’s mattress has a breathable open cell foam that sits above a memory foam layer with zoned support to help relieve pressure on the spine. Its hybrid base is made of encased springs above polyurethane foam, while the Sapira Hybrid has a high-density foam base.
This Leesa mattress also has cooling premium foam, contouring memory foam, and transition core support foam, each in a separate layer. Its transition foam layer may increase comfort for some sleepers and add durability.
Springs
The Leesa Sapira Hybrid Mattress has over 1,000 individually wrapped springs, including perimeter edge support for more usable sleep surface. Casper also has edge support for its flex coil layer. Its coil count is 338-810, depending on mattress size.
Casper has 8.5-inch coils, while Leesa has 6-inch. Some sleepers find longer coils offer better support and greater motion isolation. Others find shorter coils offer more mattress stability and better integration of the thick comfort foam above it for a comfy feel with coil support.
Covers
Both mattresses have soft, breathable knit-blend covers. Better airflow may help some people rest more comfortably at night. The Leesa mattress also has moisture-wicking properties for potentially cooler sleep.
Size Comparison
The same popular size options are available for both Casper and Leesa. The Sapira Hybrid Mattress comes in these standard US sizes:
- Twin
- Twin XL
- Full
- Queen
- King
- Cal King
Those looking for a split king setup may consider putting two twin XL mattresses together. Dimensions can vary by 2 inches on any side due to the handmade nature of the Leesa mattress. Being handmade may give it a more premium feel and more attention to detail than one produced on an automated assembly line.
Leesa vs Casper: A Look at Pros and Any Limitations
Firmness and Sleep Style
The Sapira Hybrid is medium to medium-firm, as per Leesa’s US site. The Casper model is medium.
A medium hybrid is typically popular with lighter-weight and average-weight side sleepers for balancing softness and support. The slightly firmer Leesa mattress offers a more supportive feel that certain side sleepers prefer, as do many back, stomach, and combination sleepers. Plus-size sleepers often seek medium-firm or firm for extra support.
Hybrid, Not All-Foam
Both mattresses are hybrids, which will not suit everyone. Those who find all-foam mattresses most comfortable likely grew up sleeping on them. Those who do not like the body-hugging sensation of an all-foam construction may try a hybrid mattress instead for a more lifted feel.
Some people find hybrids combine the best of both worlds with cushioning from foam and springy support. Also, it may be easier to switch sleep positions without the stuck-in feeling of some all-foam mattresses.
Support and Pressure Relief
Casper also has a memory foam layer, with firmer foam in the center, to support the waist, hips, and lower back. Softer foam under the shoulders may reduce pressure in this area. Side sleepers and restless sleepers are most likely to benefit from the targeted support and pressure relief.
Premium memory foam in Leesa’s Sapira Hybrid contours the body, cushioning key pressure points like the hips, shoulders, and lower back. Beneath it, a responsive transition layer gives additional support. Sapira Hybrid’s high-density base adds stability and encourages proper spinal alignment in various sleep positions.
Individually wrapped coils in both mattresses respond independently to the body’s shape and weight for adaptive support. That can help reduce tension in sensitive areas, like the shoulders and hips, and support the spine’s natural curves.

Breathability
Both have breathable covers to help with temperature regulation for a more comfortable sleep. Leesa’s top cover is also moisture-wicking, meaning it pulls sweat away from the skin to help keep you dry. That may make the Sapira Hybrid the right fit for some people who regularly overheat at night.
Casper’s mattress has open-cell foams to prevent overheating, while the Sapira Hybrid offers cooling capabilities with its layer of ventilated foam. They both have independently moving springs, which are known for great airflow. These mattress features help certain sleepers get fresher sleep.
Motion Isolation
The two mattresses get positive feedback online for this feature. The soft foams and individually wrapped springs in both help improve motion isolation. Many couples look for a mattress with this quality to help reduce the chances of feeling your partner’s movements, which could wake you up.
Certifications
The Leesa Sapira Hybrid Mattress has CertiPUR-US® certified foams. This highly regarded certification means the foams are free of ozone depleters, PBDE flame retardants, heavy metals like lead, formaldehyde, and certain phthalates. The foams also have low volatile organic compound (VOC) emissions, contributing to better indoor air quality. Foams in the Casper Dream are not CertiPUR-US® certified.
All Leesa mattresses are also GREENGUARD gold certified, meaning they’ve passed rigorous testing of over 360 VOCs. Choosing a low-VOC mattress is often important to households with kids, seniors, or anyone with chemical sensitivities.
Fiberglass Free
Neither mattress contains fiberglass. That may help those with sensitivities or respiratory issues sleep more comfortably without potential fiberglass-related problems, such as sneezing and itchy skin.
