Silentnight is the UK's most trusted sleep brand, handmaking mattresses in Britain for decades. Their mattresses come with a 60-night comfort exchange, long enough to know whether the firmness suits you. Free delivery is included on orders over 49 pounds, and the rolled Sleep Now mattresses carry a 10-year guarantee. We verify every Silentnight promo code on this page so you can buy with confidence and save at the same time.
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

When we get something wrong, we fix it and say so here. All corrections
- 9 October 2026
- We said Silentnight offered next-day delivery on selected items. They do not; their quickest service is 48-hour delivery on the Sleep Now rolled range.
- 9 October 2026
- We said some Silentnight mattresses came with a 365-night trial and that every mattress had a 10-year guarantee and free delivery. Silentnight offers a 60-night comfort exchange, a 5-year standard guarantee and free delivery on orders over £49.
Silentnight discount code questions
How do I apply a Silentnight promo code? Visit silentnight.co.uk, choose your mattress, and add it to the basket. During checkout you will see a promo code field - paste your code and click Apply. The discount updates your total instantly. Silentnight also offers 0% finance, which can be combined depending on the promotion.
What is the Silentnight sleep trial? Silentnight gives you up to 60 nights to decide. Sleep on the mattress for at least 28 nights, then if it still is not right you can exchange it for another product, as long as you claim within 60 nights of delivery. It is an exchange rather than a refund.
What is Miracoil and Mirapocket technology? Miracoil is Silentnight's continuous spring system with zoned support - firmer in the middle for your back and softer at the head and feet. Mirapocket uses individual pocket springs that move independently, which means less partner disturbance when sharing a bed. Some models have over 2,400 springs for extra responsiveness.
Does Silentnight offer NHS discount? Yes. Silentnight provides a 15% discount for NHS staff when you spend £300 or more. Verification is usually required through a recognised service. It is a worthwhile saving, especially on their higher-end Mirapocket or hybrid ranges.
What guarantee comes with a Silentnight mattress? Silentnight mattresses carry a 5-year guarantee as standard. The rolled mattresses in the Sleep Now range get 10 years, or the lifetime guarantee if you register within 3 months of purchase. Just make sure you use a mattress protector from day one to keep the warranty valid.
