If you’ve tried countless mattresses in-store and you know you’re a firm fanatic, it can be frustrating to find only select mattresses with that extra strong support system among a sea of soft, medium and medium-firm mattresses. Thankfully, Sealy have got just the ticket for you, with features varying from a luxury damask cover to a generous 26cm depth and orthopaedic support, not to mention the generous 30% off in the Mattress Online sale.
This firm orthopaedic mattress is designed to provide exceptional support, particularly for back and stomach sleepers. It features Sealy’s PostureTech Core Support springs, which are engineered to respond to body weight and movement, offering targeted support where it’s needed most. The mattress is constructed with soft white fibres and a damask cover, contributing to a cosy feel without retaining excessive heat. With a depth of 26cm, it’s suitable for various bed frames and offers a solid, supportive base for restful sleep.
It comes with a 60-night comfort trial, allowing you to test the mattress and exchange it if it doesn’t meet your expectations. The mattress is also handcrafted in the UK and comes with a 5-year guarantee, reflecting Sealy’s commitment to quality and customer satisfaction. We sifted through hundreds of reviews from buyers and many users report improved sleep quality and relief from back pain after switching to this mattress.

It wouldn’t be a mattress deals round up with a TEMPUR mattress entry, now would it? The Tempur Original Elite Mattress is a premium memory foam mattress designed to offer exceptional comfort and support. It features a 25cm depth, providing a medium-firm feel suitable for various sleep positions.
The mattress incorporates TEMPUR Material, originally developed by NASA (!), which adapts to your body’s shape, weight, and temperature, offering personalised support and pressure relief. This design helps reduce tossing and turning, promoting a more restful sleep. Additionally, the mattress includes a QuickRefresh cover that is easily removable and washable at up to 60°C, ensuring easy maintenance.
It is a ‘no-turn’ mattress, meaning it does not need to be flipped, which is a real bonus as mattresses can be super heavy to rotate alone. The mattress comes with a 10-year guarantee, reflecting the brand’s confidence in its longevity. While it may have a higher price point compared to other mattresses in this edit, we think the investment is justified by its advanced materials and the enhanced sleep experience it offers
When is Black Friday and Cyber Monday in the UK?
Black Friday traditionally takes place the day after Thanksgiving — a U.S. holiday celebrated on the last Thursday of November. In the UK, retailers have fully embraced the event, rolling out major discounts across the same weekend. This year, Black Friday falls on Friday 28th November, with offers expected to continue through to Cyber Monday on 1st December, ending at midnight.
Are there any Black Friday mattress sales available now?
Yes! The Black Friday mattress deals are already coming in strong! We’ve found mattress offers from brand’s like Simba, Emma, Nectar, REM-fit, Dusk, and OTTY already but make sure you bookmark this page as we’ll be updating our guide throughout Cyber weekend with the most up to date deals.
What do I need to do before buying a mattress this Black Friday?
- Assess what type of sleeper you are – front, side or back (or a combination). To do this, make note of what position you fall asleep in, and what position you wake up in.
- Make sure you know your bed’s measurements and size; often people who think they have a double bed actually have a small double, so it’s worth checking to be sure.
- Check for sleep trials if you’ve never tried the mattress you think you’d like to purchase – e.g. hybrid, pocket sprung or memory foam mattress. This will keep you covered should you not get on with it.
- Find out what firmness your current mattress is and decide whether you want to level up – i.e. go firmer – or soften up with your new mattress purchase.
What are the best mattress brands?
When it comes to the Black Friday and Cyber Monday mattress sales, knowing which brands will throw in the best sheet sets and free pillows with your purchase, which ones are going to offer the best sale prices and which ones have the best overall Black Friday deals on actually high-quality mattresses is key. Here’s our verdict on the matter…
- Best in the Glamour readers’ opinion – here at Glamour, you – the readers – love Emma mattresses. Offering up to 40% off in last year’s sale, Emma’s mattresses proved to be some of the most popular picks — and it’s easy to see why they’re set to be a favourite again for Black Friday 2025.
- Best luxe mattresses to go with The White Company or Dusk Bedding – If you’re looking for a thick, plush mattress to bring that hotel-like luxury to your bedroom, Simba’s mattresses are a top pick. While this year’s Black Friday sale hasn’t been announced yet, last year shoppers enjoyed up to 65% off everything – fingers crossed for similar savings!
- Best most affordable mattress – if you’re a student (we see that teddybear bedding in your basket…), looking for a kids bed or you simply want to save money, we’d recommend Dusk’s mattresses this Black Friday – currently on sale for as little as £379, they’re selling elevated sleep solutions for a fraction of the price.
