Why our sleep experts loved it

There's nothing quite as critical to a good night's sleep as the mattress you choose to rest on. A mattress should be more than just a resting place; it needs to provide the optimal blend of comfort, support, and luxury. From the moment it arrives at your home to the first time you sink into it for a good night’s sleep, every element of the mattress matters. Let us cue in the Hypnos Alcester Ortho Extra Mattress - a marvel of sleep technology that we've had the privilege to review. Designed with a unique blend of features, it promises a sleep experience that is so delightful, you'll wake up feeling refreshed and invigorated every morning.

How we tested

Our meticulous testing process included a two-week rigorous sleep trial. This allowed us to experience firsthand the comfort, support, and overall sleep quality provided by the Hypnos Alcester Ortho Extra Mattress. With its impressive specifications, we were excited to note how these translate to actual sleep experience. Our testing routine included observation of factors such as motion absorption, temperature regulation, suitability to various sleep positions, and overall comfort. A well-rested sleep throughout different weather conditions gave us a broad understanding of its performance.

Design and features

The Hypnos Alcester Ortho Extra Mattress is a product of master craftsmanship, from its impressive 1200 ReActivePro™ 6-turn pocket springs to its Solotex™ layer engineered from recycled plastic. Knitted into a comfortable cocoon of firm support, these 6-turn springs offer a unique sturdiness that counters motion transfer, ultimately adapting to the nuances of your body, relieving aches, and delivering tailored support. The expertly chosen materials create an eco-friendly mattress that's not just good for you, but also the environment.

Sitting on top of this is a layer of wonderfully springy and breathable cotton, designed to keep you at the right temperature all night by wicking away moisture. The overall comfort is further enhanced by a sumptuous damask cover which, besides being soft to the touch, does not retain heat and delivers long-lasting performance.

As a testament to its inherent durability and the craftsmanship involved, this firm mattress is hand-tufted to secure the fillings in place and prevent sagging or shifting over time. The hand-stitched borders are a hallmark of quality, providing reinforced edge support and extending the sleeping space all the way to the edges without any roll-off sensation.

Mattress comfort

The firmness of the Hypnos Alcester Ortho Extra mattress makes it an ideal choice for those who appreciate a stronger level of support. Its firm, supportive nature could be a game-changer for back pain sufferers, aiding in pressure relief and promoting good posture. As an orthopaedic mattress, every inch is expertly crafted to cradle the most delicate parts of your body, making sure your sleep is as revitalising as it should be.


This mattress is specifically designed to cater to back sleepers and those with certain orthopaedic requirements. The firm tension offered by the Hypnos Alcester Ortho Extra Mattress might also be suitable for some stomach sleepers. However, it's worth noting that this mattress might not be the best fit for side sleepers due to its high firmness level.

What customers thought

Feedback from customers who used this mattress consistently highlighted its orthopaedic benefits and the excellent support it provides, specifically for back sleepers. Users appreciated the firm yet comfortable sleep experience and noticed a marked improvement in their sleep quality and a significant reduction in back pain. They were particularly impressed by the mattress's ability to provide both a superior level of comfort and excellent support.

The verdict

The Hypnos Alcester Ortho Extra Mattress delighted us at every step, delivering on its promise of an exceptionally restorative sleep. It effortlessly balances firm orthopaedic support with high comfort levels, making it an ideal mattress for back sleepers or those in need of extra support. Its impressive quality and the value for money it offers are clear indicators of its unbeatable advantages. Add to this the 10-year guarantee and the royal approval from Her Majesty Queen Elizabeth II, and you have a mattress that is undeniably hard to resist. Our recommendation? Don't fight the temptation.
