Award-winning mattress maker Casper is running a flash sale on all its mattresses. You can get a 15% discount on your Casper mattress order using the code: BED15 – but you’ll need to be quick, because this deal ends today at 11:59 GMT.

Casper has two mattresses: The Casper – a popular memory foam mattress that’s so good you’ll find it recommended in our best mattress guide – and The Essential, an excellent cheaper foam mattress that provides outstanding support and comfort despite its lower price point, and is notching up rave reviews from the experts.

Both are bed in a box mattresses, which means they’re delivered vacuum-packed to your door in a conveniently sized box. And both come with a 100-night trial: if you don’t like them, you can return them and get your money back. 

With Amazon Prime Day just a month away, it’s possible we’ll see more cheap mattress deals again in July. We don’t tend to see more than 15-20% off Casper mattresses in general, though, so if you need a new one now, this flash sale is a great deal. It ends very soon though – today – so you’ll need to move quickly. 

The Casper mattress: £340-£680 (was £400-£800) for single-super king sizes
Save £60-£120
- For today only you can get 15% off The Casper mattress with Code: BED15. With four layers (24cm) of premium foam and zoned support – and thousands of five star reviews from happy customers – you’re guaranteed a great night’s sleep. Deal ends: 11:59 GMT, 11 June 2019 View Deal

The Essential mattress: £233.75-£467.50 (was £275-£550) for single-super king sizes

- Prefer the cheaper Essential mattress? There’s 15% off that too, making it even more affordable. Two layers (18cm) of breathable premium foam provide outstanding support and comfort, and you get a handy easy-to-clean zip-off cover too. Just add code: BED15 at checkout. At this price, it’s an absolute bargain. Deal ends: 11:59 GMT, 11 June 2019View Deal
