But don't sleep on this deal - aha ha ha - as it may be over by the time you wake up tomorrow

August bank holiday is coming and that can only mean one thing: the Amazon Bank Holiday Sale! Although as usual with Amazon, this actually means 'The Bank Holiday… Plus over a week's worth of the days around it… Sale!'

The event runs for eight days, through to August 30. Today's biggest deal is on Casper mattresses, with the Casper Premium Memory Foam Rolled Mattress (King Size) – one of the best mattresses you can buy, according to our list – getting a 15% price cut. 

UPDATE: This deal is currently sleeping - as in, you can’t get it if you slept on it yesterday (August 22) - but it will be BACK tomorrow (August 24). So make sure you’re awake and ready. 

Casper - a disruptive company making comfy mattresses

Casper is perhaps the biggest of all the 'mattress in a box' brands, and has revolutionised the art of buying a new mattress. This one comes with a 100-day, no-quibble testing period. If you don't like it, just send it back and get a refund. There's also a 10-year warranty, and millions of users will vouch for the comfort of its patented blend of memory foam and a springy, breathable top layer. It's 'a sleep surface that leaves you feeling perfectly supported and practically weightless.'
