The Luna® 4000 Plush Gel Memory Pocket Hybrid Mattress offers dreamy comfort. Perfectly crafted with pocket springs for full body support and comforting Gel Memory foam for a refreshing slumber.

Individualised springs encased in cloth pockets. Expertly adapting to movement to distribute personalised support to each part of your body.

Small, individually cased springs provide added comfort to the mattress whilst offering soothing pressure relief. Mini springs decrease motion transfer so you can share the bed undisturbed.

Supremely breathable and cooler than traditional memory foam. Gel foam provides fresh sleeping experience that soothes aches and pains.

Supportive foam that promotes spinal alignment and a personalised sleeping experience by moulding to your body. It is durable and resilient and it holds its shape for an extended period of time.

A sumptuously soft finish that provides additional cosiness and warmth. Knitted covers enhance airflow and are incredibly breathable. So, you can enjoy a cooler snooze.
Gentle support and a plush, softer feel

About 9.8 inches deep. Depth is an important factor when buying a mattress as it can affect the suitability for particular bedding, mattress toppers and bed frames.

Durable edge-to-edge support provides a maximised sleeping surface for a more secure sleep. Sit and lay comfortably right to the very edge with zero 'roll-off' sensation.

Offering a soothing night's rest by evenly distributing your body weight across the mattress. The pressure point relief provides the ultimate relaxation needed for a deep slumber.

For your peace of mind
The Luna® 4000 Plush Gel Memory Pocket Hybrid Mattress encourages the dreamiest sleep.
Sprung core
Crafted from durable steel and sewn into their own individual fabric pockets, 2000 pocket springs expertly respond to weight and movement to offer personalised support. This spring system also works to keep your body correctly aligned as you sleep to ease aches.
2000 mini springs provide extra comfort and breathability within the mattress for a truly cosy rest. The small shape of the springs helps to push airflow through the mattress for added freshness.
Cooler comfort
Designed to provide a blissful rest, this mattress includes a 2cm layer of Gel Memory foam. This layer is made with an open cell structure, making it breathable. This increases airflow to provide a cooler feel than standard foam. This can improve your sleep by easing the chance of overheating.
Gel Memory foam adapts to your unique shape for tailored comfort. It lifts weight off your body to improve circulation and ease built up pressure whilst allowing you to move freely without sinking in too deep.
Adding to the comfort are two 3cm layers of reflex foam that provide additional cushioning.
Perfectly balanced
Choosing a soft to medium firmness is the ideal choice if you aren't too keen on firm sleeping surfaces.
A thick foam encapsulated border helps to reinforce the perimeter of the mattress. Reducing the effects of a sagging edge. So you can enjoy sleeping right to the very edge without a roll-off feeling.
Simply the best
Designed with your comfort and convenience in mind, this mattress is delivered rolled. This makes it super easy to carry and unpack. Adding to its simplicity, it is single-sided, this means you only need to rotate it top to toe seasonally.
Complete with a 10 Year Guarantee for ultimate reassurance.
This mattress comes with a 100-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 100 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.

In store, it felt very soft when laying down but when it arrived at home, even though having it laid out for a couple of days before using, the mattress felt quite hard. After a week of using, it did soften to exactly what we wanted. Took a while for it to feel like what we wanted, but now it is amazing, so comfy and great for my aching shoulders. I do wish it had handles on the side to make it easier to move. Also has great non slip material on the bottom.

Mattress has proved to be very comfortable. It took a couple of weeks for a chemical odour to cease. The communications regarding delivery of new mattress and removal of old one lacked clarity. These suggested that the delivery team would open the packing, roll out the mattress on the bed and then remove the old mattress. The delivery team said they were only paid for delivery and removal and that placing mattress on bed was our responsibility. Given we are over 70, that could have been a big problem if we were not so fit and well-coordinated. Clarity in that regard should be carefully considered.

Nice and firm, once you get used to it after a couple of days, it’s great.

Hi, after a few months of use we are very pleased with our mattress. It has been very comfortable and helped my husband sleep well after a recent hip replacement. Moreover, we were more than satisfied with the staff at the Doncaster ( Sprorborough) branch who went out of their way to deliver the mattress speedily. Many thanks.
