Your one stop Casper guide

Searching Google for ‘Casper mattress reviews’ and feeling overwhelmed with too many options? Sit back, pat yourself on the back and enjoy a cup of tea and a biscuit. You’ve just found the best place to help you make a smart decision.

The Casper in a nutshell

The Casper is an all foam mattress made from four different layers. A breathable top layer adds bounce and keeps you cool. A memory foam layer comes next for comfort and support. A third layer helps distribute your weight and a final deeper layer provides stability and durability.

Casper’s UK invasion

The US based start-up began selling their mattress-in-a-box online in the spring of 2014. Their quirky animated ads, word of mouth sales and affordable pricing meant Casper were suddenly everywhere and revolutionised the US mattress space.

Fast forward two years and Casper’s aim to become the ‘Nike of the sleep world’ saw them expand to the UK market.

With Best Buy awards from Which & The Independent already under their belt, Casper’s UK launch is going rather well. Manufacturing their mattresses in the UK is a good start but is Casper’s success largely down to clever marketing or do they make a seriously good mattress? I’ll walk you through the data right after this Casper unboxing video…

As if by magic the Casper mattress unfurls from a 47 x 47 x 108cm box.

Unboxing Casper mattress reviews

Our introduction to Casper mattresses came via Marc Maron’s podcast. Marc (& producer Brendan) received new mattresses when Casper became a sponsor and they’ve been raving about them ever since. But Maron’s not evaluating mattresses every day so what do pro reviewers make of the Casper mattress compared to the competition?

Here’s some of Casper’s most recent accolades from comprehensive testing. As you can see it hasn’t taken long for Casper mattresses to start racking up awards since their UK launch.

One size fits all?

After extensive research Casper determined that one mattress could accommodate the vast majority of sleeping positions and body types. Which certainly agreed giving the Casper their ‘Best Buy In A Box’ award. The Independent were quick to follow suit heralding Casper as their “favourite of the new-generation bed-in-a-box options” along with their Best Buy award.

The maximum height of a Shetland pony is 107cm which just happens to be the exact height of the Casper box. Yes, this is absolutely an excuse to Photoshop an adorable photo from VisitScotland.

While TheSweetHome awarded the Leesa mattress their top foam mattress award they were quick to praise Casper as top runner-up highlighting its suitability for the not-so-still sleeper:

“The Casper’s mix of four foams may work better for people who switch positions often, especially onto their back, or for couples that include back-sleepers.”

Key Points From Mattress Reviewers

The Casper mattress scored a high sleepscore rating from mattress review websites with an average of 4 or more stars out of 5. Here’s some key points from their findings.

Joe Auer from Mattress Clarity reckons the combination of comfort foam and memory foam on the Casper mattress provide sufficient resilience for something in-between memory foam and a traditional mattress:

“If you want pressure relief but don’t like the slow-moving feel of just memory foam, the Casper could be a good choice.”

Sleepopolis says the Casper has a medium firmness feel, giving a rating of 6 out of 10 on the firmness scale (1 being very soft, 10 very firm). Honest Mattress Reviews give the Casper a firmness rating of 6.9 out of 10. Most tests put Casper in the same ballpark.

Casper mattress Reviews - Wes Anderson
“If Wes Anderson made a movie about a mattress company, it would probably look a lot like Casper.” Find out what goes on behind the curtain at Casper HQ in this enjoyable Fast Company feature.

Consumer Reports is funded solely through subscribers (no advertising) so their testing can be as unbiased and trustworthy as possible. Here’s what they said about the Casper:

“It showed only minor changes after eight years of simulated use. It transmitted little vibration from one side of the bed to the other, and changing positions was fairly easy.”

Their only quibbles were a lack of handles for turning and it was a little softer than expected.

Writing for David Kender gives a succinct summation of 18 months on a Casper after complaining about his old mattress for years…

I bought a Casper mattress a year-and-a-half ago, and only recently did I realize just how much I liked it. How did I know? Because I stopped thinking about mattresses altogether—truly the hallmark of a mattress doing its job.

Best Video Review

If you only watch one Casper mattress review video, make it this one

There are zillions of Casper mattress reviews on Youtube but too many are thin on content and thick on clickbait titles and referral links. While there are some decent Casper reviews there are only a few in-depth, unbiased examples providing real insight into what the mattress is like to live with.

Thankfully we found mattress reviewer Michael Magnuson (founder of and he’s put together an incredibly comprehensive half hour review of the 2017 Casper mattress.

After watching this video you’ll have learned more about the Casper mattress than you ever thought you needed to know. Enjoy the bowling ball and skittle test to assess whether the Casper mattress will disturb your partner’s sleep as you get up in the middle of the night.

Runner Up: A close second place goes to Justin & Crystal from Our Sleep Guide whose Casper mattress unboxing & review is just as thorough and demonstrates that it never gets old to see a massive mattress emerging from a much, much smaller box.

Casper have created a fun and quirky company who make a mighty fine mattress. They’re also one of the biggest online mattress companies on the planet so your 10 year warranty is in safe hands as they’ll be here for the long haul.

The general consensus from the best mattress review sites is that Casper’s a well made medium-firm mattress which isn’t likely to disappoint the majority of customers. At the same time the competition for bed-in-a-box mattresses keeps expanding and improving so there are genuine alternatives to Casper’s one size fits all mattress at similar prices.


  • Great for stomach and/or back sleepers
  • Ideal if you like a medium-firm feel
  • Much more supportive than a pure memory foam mattress
  • Well constructed, durable & breathable
  • 100 night trial to try it out
  • 10 year warranty


  • Weighing over 30kg means it can be difficult to rotate with no handles
  • Slighter or heavier side sleepers may find there’s too much/too little support
  • Chemical smell might last a few days
  • Edge support isn’t the best
