In July, Casper announced it was closing down UK operations. You can no longer buy Casper mattresses in the UK, but a good alternative might be an Emma Original or Emma Hybrid mattress.

We rate Casper's mattresses among the best on the market right now – and this brand has thousands of glowing reviews to back that up. There are three different options to choose from. If you're on a budget, the cheapest Casper mattress you can buy is the Original. Available in foam-only and hybrid (springs plus foam) versions, this extremely well-reviewed mattress is design to offer both support and cooling. 

Next, there's the Nova. A mid-price mattress with a plush top layer to relieve pressure and provide sumptuous comfort. Finally, there's Casper's most luxurious option: the Wave Hybrid – a 13" thick luxury mattress that's designed to provide unbeatable support for people who suffer back pain. 

We're pleased to report that Casper offers a generous 100-night free trial. That means if you don't absolutely love your mattress, Casper will pick it up and give you a full refund, which really takes the risk out of any Casper mattress deal you choose to go with. In response to the current situation, you'll also be able to return your mattress outside of this period – you just need to contact Casper during your 100-day trial and register a return reuqest.

The Casper Original is the cheapest – and most popular – of Casper's three mattresses. You can choose between a memory foam-only design or a hybrid. Both boast a smart design to provide maximum comfort and support, with three different layers of foam. The springy, breathable, open-cell top layer keeps you cool and gives the mattress some bounce, leaving you feeling perfectly supported and practically weightless; while the layers beneath provide more support, even weight distribution and better spine alignment. In the hybrid version, there's also a layer of resilient springs, for added lift, support, and airflow.

The end result is a mattress that's neither uncomfortably firm nor unpleasantly soft. It helps maintain an optimum sleeping temperature – and should provide you with years of quality sleep.

2. Nova Hybrid – Casper mattress deals

The Nova Hybrid is Casper's mid-range offering, with prices starting from $1095 for a Twin. This design sports a plush top later for an extra luxurious night's sleep. It's engineered to relieve pressure without sacrificing cooling. Elsewhere, there's a layer of perforated premium foam, a zoned layer to provide support where you need it most, and a layer of bouncy springs for extra lift. 

3. Wave Hybrid mattress deals

Alternatively, choose the Casper Wave Hybrid mattress. It's Casper's most supportive  (and expensive) mattress, made from Casper's signature pressure-relieving foams and an extra layer of high-quality springs for added bounce and luxurious support.

How good is a Casper mattress? 

It's fair to say that over the past few years, Casper has led a revolution in the way we buy mattresses. No more self-consciously lying on a bunch of beds in a showroom while a salesperson hovers eagerly nearby. Simply order this bed-in-a-box mattress online for significantly less than you'd pay in a shop, and it'll turn up compressed into a surprisingly small box, ready to unpack. If you don't get on with your new Casper mattress, you can simply return it up to 100 days later. 

Casper mattresses are made using memory foam, but boast a smart design to provide maximum comfort and support. Every Casper mattress contains four different layers of foam, each one doing a different job. The springy, breathable, open-cell top layer keeps you cool and gives the mattress some bounce, leaving you feeling perfectly supported and practically weightless; while the layers beneath provide more support, even weight distribution and better spine alignment. 

The end result is a mattress that's neither uncomfortably firm nor unpleasantly soft. It helps maintain an optimum sleeping temperature – and should provide you with years of quality sleep. Be aware, though, that once you unpack it, your Caspar mattress will take a while to decompress – up to 10 hours, so think ahead if you're planning on settling down for a good night's sleep the first day you have it.

Casper mattress price: how much do they cost? 

It's a fact of life that mattresses don't come cheap. Do a bit of research, though, and you'll find that Casper mattresses are priced pretty reasonably compared with other brands. The most popular – The Casper Original mattress – starts at $595 for an all-foam Twin at full RRP (the Original Hybrid starts at $695). Prices go up to $1495 for a Hybrid Cal King. And if it's all still a bit too rich for you then bear in mind that you can almost always find some kind of discount on these Casper mattress prices.  

Casper mattress discounts, deals and promo codes: when's the best time to bag a bargain?

Casper mattress coupons

If you were to head to the Casper site and simply order a mattress at list price, you'd be getting a pretty good deal: it's a very good mattress and the RRP is competitively priced. But it's almost criminally easy to find yourself a Casper mattress coupon, discount or promo code that'll knock a healthy chunk off the asking price. 

One of the best times of the year to bag a brilliant Casper mattress discount is Black Friday (more on that below). But you'll find great deals all year round – so if you need a new mattress now, there's no need to wait. We see good offers at Christmas and in the January sales; in March, when retailers look to sell off older stock; on Amazon Prime Day in July; and in the summer sales too. Most months, you'll find a Casper mattress deal that cuts the price by at least 15%...
