Casper Mattress Review and Ratings 2026: Is It Right for You?

This Casper mattress review will focus on the new updated version of the flagship Casper, while also mentioning the alternatives in the Casper range. Casper offers the Wave (top of its range but expensive), the new updated Casper mattress, and the lower priced Essential.

It is the mid-range 2026 Casper mattress that we shall be reviewing here. We shall first discuss its construction: the various layers that make this mattress what it is. We shall start from the top sleeping surface down to the base support layer.

Construction of the Casper Mattress

The new Casper mattress is constructed using four layers of foam. Casper does not use innersprings in any of its mattresses, so if you cannot sleep without springs, then you may think that this is not for you. However, Casper has many enticing features that may change your mind.

Cover: The cover of a mattress is more important than many people realize. It is the surface in contact with your skin. The cover of the Casper mattress is a soft, thick polyester fabric. It has been designed not to bunch up when you move around when sleeping, but quickly zaps back to its original flatness. It is a zippered cover that can easily be removed for cleaning – it is machine washable.

First Foam Layer – 1.5 inches: The first layer of foam is a proprietary foam, much like latex. It is comfortable to lie on and provides a good level of bounce for those that like this. This top Comfort Layer also relieves pressure on your shoulders, hips and other pressure points. It gives excellent support for the lower/lumbar region of your back. It also rapidly responds to pressure, and it keeps you cool at night.

Second Foam Layer – 1.5 inches: This is referred to by Casper as the Contour Layer. This is a layer of 3.5 lb memory foam which contours to your body, and thus extends the pressure relief offered by the top layer down towards the third layer. It makes for an exceptionally comfortable mattress to lie and sleep on.

Third Foam Layer – 1.5 inches: This is referred to by Casper as a Transition Layer. It is constructed using two types of polyurethane foam. There is a soft layer for the shoulders, and farther down the mattress is a firmer layer for the lower back and hip. So your shoulders are supported by a softer foam and your hips/lumbar area rest on a firmer foam. This is where Casper is unique in recognizing that your shoulders need less support then your hips and lower back do.

Fourth Foam Layer – 5 inches: This is a high-density 1.8 lb polyurethane foam referred to as the Foundation Layer. This is the base layer for the mattress that provides overall support for any type of sleeper – or sleeping position. It is nothing special – much the same type of polyurethane foam used in other mattresses as a supporting base layer. However, as it does for other brands, it also works well as a support layer for Casper mattresses.

These four distinct layers of foam add up to a 9.5-inch thick mattress that offers a good combination of comfort and support. This Casper mattress, designed in 2017 to meet modern needs, recognizes the different support needed by your shoulders and your hips and lower back.

How Firm Is the Casper Mattress?

This all might look good, but how the firm is the new Casper mattress? In fact, how do you measure firmness? Sure, foam densities and ILD figures can be quoted, but how does it really feel when you lie on it? Is it bouncy or do you get stuck in it? Does it hurt when you lie on it because it doesn’t have enough ‘give’? Let’s look at this more closely.

If you press your hand lightly on the mattress, you can feel a slight pressure and the mattress bounces back to its original flatness. Press harder, and you get a slight indentation – a bit like memory foam does, but not so ‘enfolding’ – it recovers fairly quickly.

It would likely be described by most people as being of a medium firmness – not a very scientific term, but it describes it pretty well. It’s a good ‘medium firm’ mattress. However, where the Casper mattress scores big time over its competitors is in the ‘Zoned Support‘ – the softer area where your shoulders would lie and harder for better support where your hips and lower back would lie.

When you lie on the Casper mattress you feel as if you are being held on the top of the mattress – and not sunk into it. You get a feeling of being properly supported, and you can easily move around on it without feeling stuck into it.

Edge Support: Edge support is important to many people. They may sit on the edge of the bed getting dressed, and many sit on their bed when putting their shoes on. The Casper mattress provides good edge support which not only makes the above activities easier but also supports you when you get close to the edge when sleeping.

How the Casper Mattress Suits Different Types of Sleepers

No mattress will suit everybody. The Casper mattress goes a long way towards achieving that, but even the very best mattresses cannot satisfy both lightweight and heavyweight people. It’s a huge challenge for a mattress designer to create a product that will suit both heavyweight and lightweight people equally. The following information applies generally, but may not apply universally.

Side Sleepers: The two pressure zones are ideal for side sleepers. You get comfort for your shoulders and more support for your hips where you need it. In addition, the layers of comfort latex foam and memory foam together provide good support and low pressure on the shoulders and hips.

The whole mattress construction helps to keep your spine straight when viewed from the front or back. The spine has a natural ‘S’ shape when viewed sideways, but is straight when viewed straight on. Without the correct type of support, side sleepers can have their spine moved out of alignment. The Casper mattress helps to prevent this.

Back/Stomach Sleepers: Too soft a mattress can result in insufficient support for your shoulders and hips. These can sink too far into the mattress, putting pressure on your lower back leading to back pain. Too hard a mattress can result in insufficient support for the lumbar region.

That is because the hips and shoulders do not sink enough and your lower back will be strained. Think of the ‘S’ where only the top and bottom are supported. Whether you lie on your front or back, there is not enough support for the whole spine. The Casper mattress does a good job of meeting the needs of both type of sleeper – back and stomach.

Couples Needing Bounce: Many couples like a good bouncy mattress at night. Memory foam is hopeless for a bounce. The Casper mattress is resilient and not only provides good bounciness when needed but it is also an easy mattress to move about on when people want to change position.
