Marks & Spencer discount codes & offers

Marks & Spencer (M&S) is a British retailer that sells its own-label bedding, and in the sleep range it is known mainly for British wool pocket spring mattresses, feather toppers and anti-allergy protectors. M&S dates its start to 1884, when Michael Marks took a stall at Kirkgate Market in Leeds, and the business took its name from his later partnership with Tom Spencer (M&S history).

Delivery, returns and guarantees

M&S treats mattresses as furniture, and that changes the terms. The mattress page lists furniture delivery at £15 for UK home delivery (M&S 1000 British Wool mattress), whereas smaller orders go free once you spend over £75. Furniture is on the list of items M&S takes back only in line with your statutory rights, and pillows, duvets and mattress protectors join it once their hygiene seal is broken (M&S returns). We found no sleep trial and no stated guarantee on the M&S mattress, topper or protector pages we reviewed.

The M&S range we have reviewed

Firmness is our rating, and prices are the lowest regular price across sizes at the time of writing (September 2026).

Allergy UK listing

M&S appears as a manufacturer in the Allergy UK approved products directory, which is relevant to its allergy protectors.

Who M&S suits

M&S suits a shopper who already buys bedding there, wants natural fillings such as wool, feather and cotton, and prefers a familiar high-street name. The wool mattress is a mid-priced sprung model, and the Advanced Allergy Protection protector is ranked in our best mattress protectors.

It is a weaker choice if you want to test a mattress at home or return an item you have used. With no trial, no stated guarantee and a delivery charge on furniture, M&S gives you less recourse than a brand that sells with a home trial. The feather topper is not suitable if you are allergic to feathers or avoid animal products.
