Casper Mattress Review UK | 2025

The Casper Original is an all-foam mattress consisting of three layers:

• A top layer of perforated and extra-breathable AirSpace foam
• A 3-zoned memory foam core
• A durable support foam base layer with edge support for enhanced stability

Let's look at these layers in a bit more detail. 🧐

Casper mattress foam layers

Each of the foam layers in the Casper Original mattress serves a specific purpose.

1. Top layer of AirSpace foam

Casper's unique AirSpace foam allows for enhanced breathability in the mattress.

This polyurethane foam has thousands of tiny perforations, allowing heat and humidity to escape, increasing airflow, and keeping you cool and comfortable all night long. ❄️

2. Core of memory foam

The second layer in the Casper Original mattress consists of body-conforming memory foam.

The layer has three ergonomic zones, with softer support under the shoulders and firmer support around the hips, waist, and lower back. 👌

This allows for more sinkage in the shoulder area and more support for the hips to enable ergonomic spinal alignment.

Memory foam, in general, adapts well to your body's contours and helps relieve pressure points, making the Casper a great orthopaedic mattress to eliminate back pain.

If you're a fan of memory foam, you can also try the Nectar mattress, one of our favourite memory foam mattresses currently available in the UK.

3. A durable base layer

The base of the Casper mattress is made of high-density polyurethane foam., which offers support and stability for the mattress as a whole.

It also ensures that your mattress lasts for a long time. 📅

Casper mattress cover

Casper mattress covers are made of recycled polyester, upcycled cotton, rayon, and lycra.

They have a unique and elegant design. 🌟

Can you wash the Casper mattress cover?

Unfortunately, the Casper mattress cover is not removable or washable. 🛀

We generally prefer bed-in-a-box mattresses with removable covers, as this greatly enhances the hygiene features of the mattress.

The Emma Original, for example, is similar to the Casper foam mattress but comes with a removable and machine-washable cover.

But, you can still spot-clean any stains on the Casper cover with a mild detergent.

Air-dry your mattress before putting your bedding back on, and don't saturate the stain with too much detergent - this may harm the foams. 🧼

Safeguard your bed with a mattress protector

Casper Sleep recommends that you further safeguard your bed with a mattress protector.

Waterproof mattress protectors safeguard your mattress against dirt, stains, moisture, and bacteria. 💦

They also elongate the lifespan of your mattress and help keep it in mint condition.

We really enjoyed sleeping on the Casper memory foam mattress.

Casper is often described as the Goldilocks of mattresses, giving you that "just right" feel.

We can certainly agree with this.

Another one of our favourite "Goldilocks" mattresses is the Nectar memory foam mattress.

Here's what makes the Casper so special:

• It's not too soft or too firm.
• The zoned support enables optimal spinal alignment, making it particularly great for side sleepers.
• The perforated foam top layer is comfortable to move on and makes the mattress cooler.
• The memory foam layer gives you that soft cuddly feeling, body-hugging support, excellent pressure relief, and low motion transfer.
• The durable base layer ensures you still have enough stability and support.

These features make the Casper Original foam mattress suited to a wide range of sleepers.

That said, the mattress may not be well suited to heavier-weight sleepers or those of larger builds, especially if they weigh over 100 kg (220 lbs).

This is because larger builds will sink into the foams too much, causing spinal misalignment that leads to back pains.

Larger builds need more support in all sleeping positions, and especially when sleeping on the front and back.

We'd recommend pocket-sprung or hybrid mattresses as good alternatives, since springs generally offer much more support.

Some of our favourite pocket-sprung hybrids available in the UK include:

• Simba Hybrid
• Hypnia Essential Hybrid
• DreamCloud Luxury Hybrid

You could also try the Casper Hybrid, which is still available in the UK via Mattress Online.

Our favourite UK hybrid mattresses:

Most mattresses are generally available in the standard UK mattress sizes. 🇬🇧

These include:

• Casper single mattress: 90 x 190 cm (3’ x 6’3”)
• Casper small double mattress: 120 x 190 cm (4' x 6'3")
• Casper double mattress: 135 x 190 cm (4’6” x 6’3”)
• Casper king size mattress UK: 150 x 200 cm (5’ x 6’6”)
• Casper super-king-size mattress: 180 x 200 cm (6’ x 6’6”)

But since the Casper isn't available in the UK anymore, there's no way of knowing which sizes are still floating around in second-hand markets.

Mattress Online, which sells the Casper Hybrid, has the following sizes available:

• Casper Hybrid single mattress
• Casper Hybrid small double mattress
• Casper Hybrid super-king mattress

This is a limited selection, but if you are keen on a Casper Sleep product, this is a good way to go.

What are the American Casper mattress sizes?

In the US, the Casper Original foam mattress is available in a wide range of sizes. 🇺🇸

These include the following: Twin, Twin XL, Full, Queen, King, and Californian King.

Casper mattress height

The Casper mattress has a total height of 24 cm (9.4 inches).

This is slightly lower than the bed-in-a-box standard but on par with the popular Eve mattresses.

Your standard bedding should also still fit.

Casper Sleep USA still offers a range of great sleep accessories.

These include:

• Multiple Casper pillows
• Various Casper beds and frames
• Casper duvets
• Casper weighted blankets
• Casper mattress protectors
• Casper bedding and sheets
• Casper mattress toppers
• An assortment of Casper snoozewear
• The ultra-cute Casper dog bed

Casper US also sells a variety of other mattresses, including the Casper Nova Hybrid, Casper Wave Hybrid, and the Wave Hybrid Snow.

Amazon UK actually still sells a small selection of Casper Sleep accessories, including some pillows, mattress protectors, sheets, duvets, and weighted blankets.

The Casper Original pillow is also still available in the UK via Mattress Online.

If you bought a Casper mattress before 2020, then you're in luck. 🍀

This was one of the best mattresses on the market and one we'd highly recommend.

But we wouldn't recommend buying the mattress from unauthorised sellers (or re-sellers) now, even if Casper mattress reviews are so positive.

Since Casper Sleep no longer operates in the UK, you're also likely to encounter problems when it comes to delivery, trials, returns, and warranty conditions.

You can still buy select Casper sleep products on Amazon, though!

For ease of mind, we'd recommend buying a UK memory foam mattress instead.
