100-night sleep trial - return for a full refund if not right
Every mattress comes with a hundred-night trial period. If the mattress is not comfortable after sleeping on it for a minimum of thirty nights, you can arrange a return or exchange. This removes the risk of buying a mattress online without trying it first in a showroom.
0% interest-free credit on orders over £100
Spread the cost of your mattress over monthly instalments with zero interest, available on orders above one hundred pounds. This makes premium models accessible without paying the full amount upfront. Look for the finance options during checkout to see your monthly breakdown.
Price match promise - find it cheaper and they will match it
If you spot the same mattress cheaper at another UK retailer, Mattress Online will match that price. Contact their team before placing your order with details of the competitor listing. This means you do not need to compromise on service or delivery to get the lowest price available.
Bundle a mattress and bed frame for combined savings
Buying a mattress and matching bed frame together unlocks a package price that works out cheaper than ordering them separately. The discount is applied automatically when both items are in your basket - no code needed. Look for the bundle badge on compatible product pages.
Halloween flash deals on selected bedroom furniture
A short-run Halloween promotion is live with reduced prices on a curated selection of bed frames and mattresses. Flash deals like this typically last only a few days and the stock is limited to what is in the warehouse, so checking early gives you the widest choice.
Free delivery on all mattress orders
Mattress Online includes free next-day delivery on most mattress purchases, which removes a significant hidden cost that many competitors add at checkout. Some remote postcodes may carry a surcharge, so enter your address early in the checkout flow to confirm.
Black Friday mattress deals - early reductions now live
Black Friday pricing has started appearing on selected lines ahead of the main event. Historically, Mattress Online runs some of its deepest discounts during this period, so if you can wait until closer to the date, the savings tend to increase. Current reductions are already worth browsing.
£200 off selected premium mattress orders
A flat two hundred pounds comes off orders on higher-end mattress models, which is a bigger cash saving than a percentage code on premium products that already cost over a thousand pounds. Look for the qualifying models marked with the offer badge on product pages.
Up to 5% off everything site-wide with a promo code
A lower-percentage code that applies to the entire site with no product restrictions. While five percent is less than the ten percent codes above, this one may remain valid after the higher-value codes have expired, giving you a fallback option for a smaller but still useful reduction.
Up to 15% off adjustable bed bases
Adjustable bases qualify for their own discount tier, with up to fifteen percent off selected models. These bases cost significantly more than standard frames, so even a moderate percentage translates to a substantial cash saving on the final price.
Up to 15% off pillows in the Mattress Online sale
Pillows are often overlooked when buying a new mattress, but the current sale takes up to fifteen percent off selected pillow lines. A good opportunity to replace tired pillows at the same time as your mattress without paying full price for both.
10% off everything with an alternative promo code
A second active code gives the same ten percent discount site-wide. If the first code has reached its usage limit or has expired, this one serves as a backup for the same saving. Apply it in the promo code field during checkout and the reduction appears before payment.
10% off your entire Mattress Online order
A straightforward ten percent comes off your basket total when the promotional code is applied at checkout. Works across mattresses, bed frames, and accessories in the same order, making it particularly useful if you are kitting out a whole bedroom rather than buying a single item.
Up to 50% off in the Mattress Online sale event
The sale section is where the biggest reductions live - currently featuring half-price deals on selected mattress lines from major brands. Stock shifts quickly on the deepest discounts, so the best-value models tend to go early. Worth checking before committing to a full-price purchase elsewhere.
