More ways to get a Mattress Online discount

Plan your free delivery

To get your items with free next day delivery, make sure you order by 4pm from Monday to Thursday. If you are ordering on a Sunday, the cut-off is 3pm. Planning your purchase around these times ensures you will not miss out on this convenient and money-saving delivery option.

Make the most of your trial period

The free 60-night comfort trial gives you confidence in your purchase. Remember that you need to try the mattress for a minimum of thirty nights before you can arrange an exchange. This ensures you have enough time to properly adjust to your new mattress before making a final decision.

News

A new store adds more ways to try mattresses

Mattress Online has opened its fourth physical shop in 2024, adding an in‑person way to test mattresses and get advice. You can browse the exact models stocked in the new store online first, then visit to feel firmness and finishes for yourself. It’s handy if you like to compare before ordering at home. Thinking of buying soon? Take a quick look at promotions as you plan.

Recycling service helps keep mattresses out of landfill

Mattress Online’s sustainability update highlights a not‑for‑profit pickup that more than one in six customers use, saving over 15,000 mattresses from landfill each year. Materials are repurposed — metal into new springs, fabric into blankets for animals — and stats are based on orders from May 2023 to January 2024. It’s an easy add‑on if you want a clutter‑free swap on delivery day. Planning a refresh? Take a minute to explore promotions.

Mattress Online earns a 2024 business award

The brand has been named a winner in the SME Business Elite Awards 2024 for Best Online Mattress & Bed Retailer. This recognition reflects ongoing work on service and logistics. For you, it means shopping with a retailer whose performance is independently acknowledged. If you’re comparing options, it can be a helpful tie‑breaker while you read specs and reviews. While you browse, feel free to check current promotions too.
