The original Casper mattress is an all-foam mattress that combines a latex-like foam top layer with a middle memory foam layer and dense foam base layer. Unlike the Casper, the Layla has two sides with different firmness levels. The firm side features a thin layer of pressure-relieving memory foam, while the soft side has a thicker layer of memory foam, plus a convoluted foam transition layer.
The Layla is an ideal choice for those new to the bed-in-a-box market who aren’t sure if they like a soft or firm mattress and want multiple firmness options. It’s also the best mattress for side sleepers in this comparison. You’ll like the Casper if you want a memory foam feel without feeling “stuck” in your mattress. The Casper is also a great pick for combination sleepers who change their sleeping position throughout the night.

Mattress firmness is subjective to each person, but generally, you can gauge how a mattress feels by using a firmness scale. The mattress firmness scale ranges from 1–10. Softer beds fall lower on the spectrum, while firmer beds are higher. If you have a lightweight body type, you’re more likely to perceive a mattress as firmer than advertised. The opposite is true for heavyweight sleepers: If you’re in that category, check out the best mattresses for heavy sleepers.
The Layla has two firmness levels: soft and firm. We think the “firm side” of the Layla is more like medium-firm—around 6.5/10—and the soft side is more like medium-soft, or 5.5/10. On the other hand, the Casper is a true medium-firm mattress. We think it’s around 6/10 on the firmness scale.
If you’re a light sleeper or someone who shares your bed, chances are that you appreciate when a mattress isolates motion at its source. Foam mattresses normally do a great job of absorbing movement, and this is true for both the Layla and the Casper. Still, Layla’s memory foam layers reduce motion transfer a little better than the foam layers on the Casper, especially on the soft side.
Edge support is an often overrated category, but it’s really important if you sit or sleep on the edges of your mattress. Mattresses with the best edge support incorporate high density foams or extra sturdy coils around the perimeter of the bed. Neither the Layla nor the Casper have any of these features, but they provide decent edge support nonetheless. We think the Casper has the better edge support of the two, but the firm side of the Layla isn’t far behind.
Memory foam is known for its incredible pressure relief, and both of these mattresses use at least one memory foam layer. It’s no surprise that the soft side of the Layla provides more pressure relief than the firm side. Still, we think both sides have sufficient cushioning, making them great mattresses for back sleepers. The soft side is best for side sleepers. Casper also offers good pressure relief, and is comparable to the firm side of the Layla.
Spine alignment is another way of saying “healthy sleep posture.” A mattress that supports spinal alignment is one that keeps your back in its neutral “S” curve while you sleep. Good spinal alignment also looks like a straight line from the base of your neck to your tailbone when you’re lying on your side.
Both of these mattresses keep your spine aligned, but the Casper does an even better job of evenly distributing your body weight. In that regard, it’s the better mattress for those with back pain.

Mattress longevity is influenced by its construction, materials, and level of use. With proper care and cleaning, a memory foam mattress like the Layla or Casper can last you upwards of seven to 10 years. Plus, Casper customers are covered by a 10-year warranty. Layla customers get a Lifetime warranty, as long as they are the original owner of the mattress.
Mattress temperature can have a big effect on your quality of sleep. Foam mattresses tend to retain heat more than those with innerspring layers, but Casper and Layla both deploy cooling technologies to give the mattresses a more temperature-neutral feel.
The second layer of the Layla is convoluted (wavy), which creates channels for airflow. The Casper is made with breathable, open-cell foam that’s essentially hole-punched for added airflow. Additionally, both mattresses have polyester mattress covers that allow warm air to escape from the foam. If you’re a hot sleeper, see our list of the best cooling mattresses.

The Casper mattress has a simple three-layer construction that’s equally pressure-relieving and supportive. On top is a layer of AirScape foam that’s perforated to improve air circulation. This layer has the buoyancy of latex with the softness of plush polyfoam. The transition layer is divided into three zones that are softer under your shoulders and firmer under your hips. At its base, the Casper is supported by high-density polyfoam that helps to prevent sagging.

The Layla mattress has a polyester blend cover that’s infused with a cooling agent called ThermoGel. The soft side of the mattress is made with a thicker layer of plush memory foam and a layer of convoluted transition foam. The other side of the mattress is topped with a thinner layer of memory foam. Both sides of the mattress are infused with copper, which helps with odor control and temperature regulation. The core of the mattress is made of a dense layer base foam.

The Layla and Casper are both high-quality, all-foam mattresses. We favor the Casper for combination sleepers and back sleepers. The firm side of the Layla is also a smart choice for back sleepers, and the soft side is ideal for side sleepers. Lightweight stomach sleepers may get enough lumbar support on the Casper or on the firm side of the Layla, but average or heavyweight stomach sleepers need a firmer mattress. Lastly, the Layla isolates motion better for couples.
