It's fair to say that over the last 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 nearby. Just order online for significantly less than you'd pay in a shop, and it turns up compressed into a surprisingly small box, ready to unpack. And if you don't get on with your new Casper mattress, you can simply return it up to 100 days later.
Made with memory foam rather than springs, Casper mattresses tend to be priced more reasonably than some other leading mattresses – but you can save even more money by finding a Casper mattress coupon, discount or deal. We've done the hard work for you – read on for today's cheapest Casper mattress prices...
The best Casper mattress deals
Reasons to buy
Reasons to avoid
So how good is a Casper mattress, anyway?
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 RRP for a single Casper mattress is £375; for a double, it's £575. If you need a king size mattress, it'll cost you £650, while an extravagant super king is £750.
Remember, though, that you can almost always find some kind of discount on these Casper mattress prices. And if it's all still a bit too rich for you then bear in mind that Casper has recently launched its new Essential mattress, with only two layers of memory foam, starting at just £275 for the single model and going up to £550 for a super king. Bargain.
Casper mattress discounts, deals and promo codes
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. 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.
If you're not in a hurry to get your mattress, you'll find that some times of year can be better than others for getting a Casper mattress discount – for example, we saw a Black Friday Casper mattress deal last year that knocked 20 per cent off all Casper sleep products.
However Casper's keen for your custom and runs regular offers, most recently taking 15% off for World Sleep Day, and to mark the clocks going forward for daylight saving. Here are the best Casper mattress coupons and deals available right now.
