No code needed
10-year guarantee on mattresses
Marks and Spencer's offers are listed below, and they need no code.
The home sale events, the Sparks member offers and whatever code is showing in the offers above are the three ways to pay less at M&S, so take the best of them and put it in the promotion field before you pay. The M&S Collection beds are UK-made and have carried a ten-year guarantee, while the branded ones come with the maker's own. Mattress delivery is charged and puts the mattress in the room you pick, so book a nominated day if you need to be in for it.
These codes come from retailers we work with. If you use one and buy, the retailer pays us a commission. It does not change the price you pay. Codes come from the retailers’ affiliate networks and our sync checks them regularly; the date on each card is when that code was last checked. How we make money

Ways to save at Marks and Spencer
- Put the delivery charge in the maths. Mattress delivery is charged at M&S and includes the room of your choice, and a nominated day is priced differently again for a mattress. Add it to the total before you compare the price with anywhere else.
- Be signed in to Sparks before you shop. Sparks is the M&S loyalty scheme, and member offers and personalised discounts arrive through it, so join before you fill the bag rather than after.
- Buy during the home sale events. M&S runs home sales through the year, and a code applied over a sale price is the best this page gets. Try yours in the bag and pay the lower of the two.
- Check whose guarantee you are actually getting. An M&S Collection bed is UK-made and has carried a ten-year guarantee. A branded mattress sold at M&S carries that brand's guarantee instead, which can be half the length, so read the listing rather than assuming.
- Decide before it is unwrapped. Furniture is excluded from M&S goodwill returns, so a mattress goes back on your statutory rights and there is no sleep trial behind you.
- Bedding bundles are where a homeware code stretches. Duvets, pillows and protectors add up fast, and a percentage across a bundle beats the same percentage on a single item.

Delivery, returns and codes at Marks and Spencer
Delivery
Pay the mattress delivery charge at M&S and the bed goes into the room you point at rather than being left in the hall. A nominated day is priced separately again on a mattress, worth paying if you cannot give up a whole day waiting in. Mainland addresses are straightforward; Ireland and the remote postcodes take longer.
Returns
No sleep trial, so the choice has to be right first time
Furniture sits outside the goodwill returns the rest of M&S runs on, which means a mattress goes back on your statutory rights and a change of heart is not covered. Faults go through customer service for a repair, a replacement or a refund. Who stands behind the bed depends on whose name is on it: M&S Collection mattresses have carried ten years, while a branded mattress comes with its maker's guarantee, sometimes half that length.
Using codes
M&S codes and the promotion field
M&S codes go into the promotion code field as you check out, and the bag total tells you whether yours has taken. Some are department-specific, so check the terms stretch to home and bedroom before you count on the saving.

- Sparks member exclusive codes
- Free delivery promotions

What an M&S code is good for
Bedding first, and bedroom furniture when a home event is running. The mattress side is a short range: M&S Collection beds, UK-made, with an anti-allergy cover and ten years of guarantee behind them, plus a few branded mattresses carrying the maker's own guarantee. Delivery is charged and there is no sleep trial, so the sale price and the code are the whole of the value. Spend it on an M&S Collection mattress or on the bedding, and price any branded bed against the brand's own shop before you buy it here.
