If you’re here, you probably got a good look at the adorable animals that Casper has marched out to help sell their mattresses. Who doesn’t love a baby goat? We know we do.

But what’s the deal with their mattress? Is it worthy of all the internet buzz surrounding this brand and its products? In this Casper mattress review, we’ll check out their flagship mattress model that launched the now-famous brand back in 2014.

Casper is always innovating, and they have had a few updates since then (including a brand new cover and new layer of breathable foam in 2020), and we’ll break them all down and what they mean for you, the sleeper. Does it sleep cool? Can couples share it easily?

Stay tuned, as we go through the details. Or skip to the bottom to see how it scores in individual categories.

Who Do We Think Matches With Casper?

  • Versatility Fans – If you’re in a couple and your partner has a different body type (80% of couples are in this boat) or you’re a person who switches positions a lot, you might like how versatile Casper mattress is. They’ve built this bed to work with multiple shapes in different positions by strategically layering their foam.

  • Spine Alignment Seekers – Having problems sleeping in a neutral position? Zoning in Casper may help you out. Firmer foam in the center of the bed helps hold your hips in line, which can be a struggle, especially for stomach sleepers.

  • Hot Sleepers – If you’ve shied away from foam beds in the past because of heat retention concerns, you have little to worry about with Casper mattress.

Possible Casper Complaints:

  • No Innerspring Feel – This is an all-foam bed, as as such as some pretty great motion isolation, but if you want more of an innerspring bounce in your bed, you may steer towards the company’s hybrid mattress.

  • Foam Doesn’t Slowly Respond – Fans of traditional memory foam beds are often looking for materials that slowly respond, but that’s not the feel here. By building the top layers with responsive foams, the brand aims to make repositioning easier and provide a less “stuck” feeling.

Construction: What’s inside Casper?

Casper mattress is a bed-in-a-box foam brand that stands 12 inches tall. Its four layers are wrapped in a durable polyester fabric.

  • The first layer is perforated proprietary comfort foam called AirScape™ that gives the mattress some bounce and breathability to keep the surface from overheating.
  • The second layer is 2 inches of Zoned Support™, a transition layer that is firmer in the center of the bed where your hips are positioned to help with the extra weight that tends to concentrate in this region, but softer around your shoulders and knees, for additional pressure relief. Since your body is getting tailored firmness levels, your spine should remain in neutral alignment.
  • The last layer is a layer of dense foam that lends durability, provides support, and creates the overall foundation of the mattress.

First Impression: How Does It Feel?

The outsides of this mattress look sporty and modern, with grey side panels and white top. The top feels soft and cool to the touch. Pressing into the foams, you should notice how responsive they feel or how quickly they regain their shape when pressure is released. Pushing deeper, you’ll feel the slower responding memory foam that was built to conform to your shape.

Lying down, you should feel immediate sinkage into the top layer of breathable foams as the lower layer of memory foam slowly conforms to the shape of your body. With built-in gradual transitions between each layer of foam, you shouldn’t feel “bottomed out” or up against the firmness of the base, though the supportive system should keep your body level, using the zoning in the third layer.

Firmness Scale: 6/10

Pressure Relief

When more weight is concentrated on one part of your body more than another, this creates what we call “pressure” which can translate into soreness come morning if you’ve slept in a bed that’s not right for you. Using graduated firmness and zoning in their foams, Casper mattress works to ensure that your weight is evenly balanced.

There is slightly less sinkage in this bed than one might expect from a traditional memory foam bed, and most sleepers can expect to sleep closer to the surface of the bed. You should sink in for a gently cradled feel that works to relieve pressure with the foams working to balance your weight and filling in any gaps caused by curves in your shape. Because you don’t sink deeply and the foams are responsive, repositioning in this bed is simple to manage.


The firmness of the base is balanced by the softer top to put this bed at a versatile 6 on our firmness scale. This score is ideal for many different body types and shapes.

However, the real star of this show is the zoning that runs through the middle of the bed, which helps to support sleepers throughout their hips. This is the area where most people carry the most weight and commonly the most excess weight for heavier sleepers.

Beneath this layer is a robust support foam that forms the foundation of the bed and completes the support system designed to keep all shapes pressure-free and correctly balanced. It provides a small amount of “push-back” or bounce that aids in repositioning.

Preference-based Features


Though there are some pop-up and retail locations for Casper products cropping up nationwide, the company still sells online, a business practice that helps reduce costs by eliminating the middle man and delivering directly to consumers in an easier to ship container.

Zoned Support System

The third layer of this bed provides a bit of extra support in the center of the mattress to promote better spine alignment under the hips without sacrificing the soft pressure relief usually required in the shoulder area.

Breathable, Responsive Foams for Cooling

When air can move quickly through the memory foam, there is less of a chance that body heat will become trapped, which is Casper’s strategy with its top layer of proprietary foam.

Great Motion Isolation

Though there is some bounce coming from the base layer, the memory foam here works exceptionally well here to trap vibrations caused by a sleeper’s movements before they travel across the bed to wake a sleeping partner or child. This is a great feature that couples usually gravitate towards.

Adjustable Base Compatible

If you want to use an adjustable base with this bed, the manufacturer had designed one for their line of mattresses, though it should also be compatible with other models.

Overall Summary

The name of Casper’s mattress game is versatility and its flagship mattress has definitely made its mark on the industry. Since it’s so accommodating to different sleepers, especially with Zoned Support™, there’s a great chance you’re going to love it.

Side Sleeping Icon

Side Sleepers


Most side sleepers will notice the classic pressure relief of memory foams and find that the bed conforms nicely to their curves while keeping their spine in neutral alignment. Side sleepers often experience pressure in their hips and shoulders in this position because their weight is concentrated on a smaller area.

If you’re exceptionally curvier or prefer a softer bed, you may consider looking at the Wave, Casper’s luxury brand that has an advanced support system and is scored for firmness at 4.5.

Back Sleeping Icon

Back Sleepers


Most back sleepers will appreciate the medium-firm feel and extra support beneath their hips that helps keep their spine aligned while the foam conforms to the curve of their lower back. The medium-firm feel should suit a majority of back sleepers who prefer a deeper cradle, though if you prefer a deeper sink, you may want to check out the Wave. For a touch of added firmness, go with the hybrid version of this bed.

Stomach Sleeping Icon

Stomach Sleepers


Stomach sleepers need a bed that is firm enough so their hips do not sink too low, forcing their spine into an awkward angle. The Zoned Support™ shines for those in the prone position by adding extra foam where it’s needed most for a majority of sleepers.

However, if you prefer extra support or are substantially heavier than average, we might recommend you take a look at Casper’s hybrid mattress offerings.

Combination Sleeping Icon

Combination Sleepers


If you are someone who falls asleep in one position and wakes up in another, you’re not alone. Many sleepers are what we call “combo sleepers.” These folks need to look at versatile brands that ease repositioning with responsive materials and accommodate different positions throughout the night. Casper mattress shines in this area, and we think this is an ideal choice for people who fit this category.

Couples Icon



Sleeping partners are very seldom the same size and shape and rarely have the same sleep schedule, so they need to shop versatility, low motion transfer, and edge support. Bounce is also a consideration for those who are sexually active. Casper mattress works extremely well for accommodating different body shapes and reducing the amount of motion that transfers. Couples who prefer more bounce and slightly better edge support may go with the hybrids, though there might be a slight sacrifice with motion isolation.

Heavy Sleepers Icon

Heavy Sleepers


Casper is an extremely versatile bed among a variety of different weights, though the hybrid selections, particular the Wave hybrid, might be a better pick for those who are substantially heavier than average (over 250) and need a little extra support.

Light Weight Sleepers

Light-Weight Sleepers


The original Casper mattress is our choice among this company’s line for light-weight sleepers (though those on a tight budget may also consider the Essential.) The graduated foams work to provide support and pressure relief without requiring your weight to push through to the foundation, which is great news for those with below-average body weights who prefer to sleep gently cradled. If you’re looking for a slightly deeper sink, the Wave may be more your style.

Overall Value


Casper takes the time to do their research and listen to customer feedback, and the result is a bed that should accommodate a lot of different people, including couples looking to share or combo sleepers wanting to feel comfortable in all their preferred positions.

Having a new mattress that should adjust to your changing needs and preferences over time (pregnancies, injuries, marriages, and aging) drives up the value of this product and the risk-free trial seals the deal.
