The Sleep Shop Discount Codes & Promo Codes - Verified July 2026

There's no NHS, Blue Light or key-worker listing on thesleepshop.co.uk. If you hold one of those cards, the price match guarantee does a similar job. Find the identical mattress cheaper at another UK mainland retailer, with VAT and delivery included, then ask The Sleep Shop to match it before you place the order.

The Sleep Shop doesn't announce sale dates ahead of time, so a live code beats holding out for an event that may be weeks away. If nothing is listed when you shop, lean on what never switches off: the price match guarantee against mainland UK competitors, and mattress delivery that costs nothing at any order size.

Not against codes. The price match guarantee covers new, identical, in-stock products at any UK mainland competitor, including websites, with VAT and delivery counted in the comparison, but it excludes voucher codes, cashback offers, factory outlets, auction sites and membership clubs, and matches remain at the retailer's discretion. Compare listed shelf prices when you make the request.

Mattresses are delivered free to UK mainland addresses regardless of order value, and any order over £300 ships free. In-stock items ordered before 4pm arrive the next working day at no charge; after 4pm, allow two working days. Saturday delivery adds £30, pillows normally cost £5.95 to send, and the Scottish Highlands, Grampians, Northern and Southern Ireland, Isle of Man and Isle of Wight carry extra charges.

Mattresses showing the Sleep Trial logo carry a minimum of 60 nights, and lengths vary by product. It works as an exchange rather than a refund: sleep on the mattress for at least 30 nights first, keep a mattress protector on throughout, then swap once for an alternative model in the same size. You pay the difference for a dearer choice and receive store credit if the replacement is £100 or more cheaper.

Only while it stays sealed. Returns must be flagged within 14 days of receipt, unused and unopened in the original manufacturer's packaging, with the buyer paying return carriage (£40 if The Sleep Shop collects). Once a mattress is out of its wrapping it cannot be returned, which is why the exchange-based sleep trial on trial-logo models matters if you are unsure of your choice.

Yes, through its Remove & Recycle service at £24.99. The old mattress is collected on the day the new one arrives and passed to RAMR-approved recycling partners. Book it alongside a like-for-like purchase, and note it does not run with next-day delivery, so choose a standard slot if you need the collection.
