Frequently Asked Questions

How do I apply a Mattress Next Day promo code?

At mattressnextday.co.uk, add your mattress to the basket and proceed to checkout. You will see a voucher or promo code box — paste your code and hit Apply. The discount is deducted from the total before payment. If the code fails, double-check any brand or range exclusions.

Is Mattress Next Day delivery actually next day?

Yes, and it is free. Order by 6pm and they will deliver the next day to most UK mainland addresses. You get a 2-hour delivery window confirmed by text and email the day before, and you can choose specific time slots including before 10am, late morning, afternoon, or evening.

What is the Mattress Next Day sleep trial?

They offer a 100-night sleep trial. If the mattress is not right for you, they will let you swap it for a different model. This is a genuine exchange — not just a refund — so you get to try an alternative without starting from scratch.

Does Mattress Next Day offer NHS discount?

Yes. NHS and healthcare workers can get up to 20% off, particularly through their Subscribe and Save programme. Students can also save up to 15% off. You may need to verify your status through a third-party service before the discount is applied.

Can Mattress Next Day remove my old mattress?

Yes. They offer an old mattress removal service that you can add at checkout. Their delivery team will take your old mattress away when they deliver the new one, which saves you having to arrange a separate collection or trip to the recycling centre.
