Fall into a blissful slumber with the Luna 4000 Support Gel Memory Pocket Hybrid Mattress. Delicately supporting your body so you can wake feeling refreshed.

Memory foam creates a cushioned feel by cradling to your unique shape. Enhancing the remarkable comfort, the foam has a sumptuous feel, delivering a cosy sleep.

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.

Removable covers are convenient and keep mattress maintenance simple. Easily remove the cover and wash to preserve the mattress quality.

A micro-quilted cover provides a smooth and soft finish to a mattress. The fabric is stitched into the filling inside the mattress to give it the plush quilted feel.

A rolled-up mattress is efficiently packaged for easy manoeuvring. Because of its smaller, compact design, less delivery vans are needed, providing a great environmentally-friendly option.
Firmer than a medium mattress for extra support

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.

Helping to promote a healthy sleeping position. Orthopaedic support is specially designed to provide enhanced spinal alignment, joint support and improve posture.

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.

Top-rated!
Here at Mattress Online, we've given this mattress our own stamp of approval as it's one of our Top Picks for 2025! We're confident you'll love this mattress and everything it has to offer, so why not treat yourself today.
Orthopaedic support
Engineered to provide sumptuous care to your back, shoulders and neck. The core structure is made from 2000 full size pocket springs. Created from robust steel, these springs are enclosed in individual pockets. They are then attached to each other to create a sturdy layer. The individual nature of pocket springs allows them to react to movement. Providing tailored support to your body in all the right places.
An additional 2000 mini pocket springs are incorporated within the interior support system of the mattress. These springs take pressure relieving comfort to a whole new level. A secure core means you will benefit from zero roll-together. So you can share the bed without worries about rolling into each other or motion disturbance.
Cooler nights
If you're fed up of spending your summers overheating or you often wake feeling sweaty and depleted, this Luna mattress is perfect for you. Featuring soothing layers of Cool Gel Memory foam. Unlike traditional Memory foam, the construction of Luna's cooling foam is breathable. Creating a refreshingly dreamy sleep environment.
Let yourself sink in as the Memory foam delicately shapes around you. Cocooning you in the most delightful way. Without the risk of feeling stuck or overheating. Perfectly relieving pain and pressure around your joints and muscles.
Finished with a layer of Cool Gel Memory foam quilted into the mattress cover. To make it even better, this cover is removable so you don't have to stress about spills and stains. Simply remove the cover and dry clean only to benefit from a flawlessly hygienic sleep surface.
Perfectly sturdy
The best feature a mattress can have is durability and longevity. Designed with a secure foam encapsulated border this mattress is extremely strong. Holding up against weight so you can sit and sleep right to edge without a risk of falling due to a sagging border.
Ideally medium-firm structure offers optimal support to those who sleep on their back. Keeping their spine and neck in correct alignment to alleviate and avoid pain.
The reliable choice
Treat yourself to a mattress that will stand the test of time. With minimal maintenance, this single-sided mattress just requires rotation every 6 months. Providing you with indulgent comfort in return.
Purchase with confidence with a 10 Year Guarantee.
This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 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.

Good mattress

This mattress is, by far, the best mattress I've used in about 10 years. I can't believe how deeply I've been sleeping. If you've got any aches and pains or are on the heavy side, like myself, then you'll love it too. Will be purchasing another for the campervan soon.

Been using this now for over a month and I am genuinely pleased, the quality of my sleep has improved significanly, As a side sleeper, If you want a medium to firm mattess this is excellent, the hybrid foam top layer has some give and you sink into it a little, but are also immediately supported and dont sink too much so its the right balance imo. I searched for mattresses for sometime, and tested many in person at several bed retail outlets, but I did not want to spend over a £1000 on a mattress so I looked online and I'd say this easily compares to mattresses with a £1000+ price tag in stores. really good value for money.

I am enjoying this mattress thus far. This was a swap after I did not get on well with a different brand mattress . Have slipped discs in back and inflamed hip. Sleep quality has improved and I do not wake up so achy
