Casper is celebrating its sixth birthday, and to mark the occasion it's offering you 30% off your whole shopping basket (except the company's Glow light). To claim, all you have to do is add the code HAPPYBEDDAY at checkout. Not the best pun, but a very good deal nonetheless.

Hurry though, this offer ends 27 April (11.59pm). Missed the boat? Try our roundup of the best cheap mattress deals

Award-winning mattress maker Casper has three excellent mattresses. The Casper is a popular memory foam mattress that ranks very strongly in our best mattress guide (it also makes some of the best sheets around). The Essential is a cheaper foam mattress that provides outstanding support and comfort, despite its lower price, and is notching up rave reviews from the experts. And the latest model is The Hybrid, which Casper claims is its "most supportive yet". See how it fares against a main competitor in our Purple vs Casper mattress showdown.

All three are bed in a box mattresses, which means they’ll be delivered vacuum-packed to your door in a conveniently sized box. All deliveries are contact-free, and will arrive in 1-3 business days. And they all come with a risk-free 100-night trial: if you don’t like them, you can return them and get your money back. 

With this deal, you'll get 30% cut from your total bill, so that includes the mattresses as well as Casper's quality pillows, bedding and even bed frames. Check out the savings you'll make on the mattresses alone...
