What our reviewers found

Pros

  • Offers an excellent balance of comfort and support, making it ideal for varied sleeping positions.
  • Firm support with a little give on top, which owners with hip and back trouble say suits them.
  • High-quality construction evident, promising durability and long-lasting use.
  • Designed to minimise movement disturbances for an undisturbed night's sleep.
  • Owners call it good value, and its 2000 full-size springs are a solid count for a budget brand.

Cons

  • For those who aren't particularly strong or mobile, removing the wrapping on the Luna 4000 Support Gel Memory Pocket Hybrid Mattress is a struggle, as one owner found.
  • Side sleepers with an hourglass figure will want more sink at the hip than this gives.
  • Given its firm nature, anyone who wants a plush, soft surface will find the Luna 4000 too firm.
  • Lighter-weight sleepers will find it firm, and on their side this medium-firm is close to a plank.
  • This mattress being single-sided, you can only rotate it, never flip it, and for me a turnable mattress wears longer.

Everyone aspires to have a soothing sleep, a sleep where you wake up feeling vigilant and re-energised, ready to conquer a new day. The comfort of your sleep largely comes down to the type of mattress which cradles you through the night. Let me introduce to you the Luna 4000 Support Gel Memory Pocket Hybrid Mattress, a mattress that offers a potpourri of comforting features to help you achieve your well-deserved restful night. Offering personalised support, the Luna 4000 takes mattress technology to a whole new level. But how well does it perform in practice? Let's find out.

How we assessed it

The 4000 in the name is two sets of pocket springs added together: 2000 full-sized springs in the core and 2000 mini springs in the comfort layers. With them come two 3cm layers of reflex foam and a 2cm layer of gel memory foam, all inside a foam encapsulated border, in a mattress 25cm deep. To my mind a count that high is a marketing number, so judge it on the layers. A memory foam top only 2cm thick over that much springing makes this a supportive, medium to firm bed with a thin cushion on the surface, and the foam border keeps the edge usable on a double.

Design and Features

The Luna 4000 is a product of thoughtful design - an amalgamation of well-considered attributes. At the core of its construction, it has 2000 full-sized pocket springs individually encased. Pocket springs are what I'd pick every time, and one owner's description, "Superbly comfortable as it supports all of your body", is what a unit like this should deliver.

Adding further value are the 2000 additional mini pocket springs peppered within the mattress' interior support system. The inclusion of these springs takes comfort notches higher, providing you with the soothing relief of a tranquil night's sleep. Their presence brings a welcome reduction in motion transfer, to ensure your tranquillity is unbroken, even with a restless companion sharing the bed.

It also comes with a layer of cooling gel memory foam, a feature I'm generally in favour of, because gel foam makes a mild but worthwhile difference. It is still memory foam next to your body, though, and one owner's praise was that it "keeps a good warm temperature", so a very hot sleeper should not expect it to feel cold. This cooling foam brings about a refreshingly peaceful sleep environment that your nocturnal self would be thankful for.

With its removable cover, maintaining the mattress is an effortless task. This was a feature I found particularly pragmatic, and it eased worries about potential stains seeping into the fabric and ruining the mattress.

Mattress Comfort

Now, if there's one thing that you cannot compromise on with a mattress, it certainly is comfort. The Luna 4000 has a medium-firm structure that suits people who sleep on their backs.

Being a memory foam construction, it almost softly envelops your body providing a cushy, familiar feel that is as cocooning as a warm hug. The foam contours delicately around you, taking pressure off your joints and muscles. It traps less heat than an all-foam bed, because the memory foam is only a 2cm layer and the springs underneath leave room for air to move. For feel, owners describe a firm mattress with a little give on top. One side sleeper wrote that "you sink into it a little, but are also immediately supported", and another called it "firm but still enough give to make it feel cozy". That fits a thin foam top over a medium to firm spring unit, so expect the firmer end of medium-firm.

Suitability

In my opinion, the Luna 4000 is in particular versatile in its appeal. Its medium-firm structure, topped with a layer of soothing memory foam, caters to a wide range of sleepers. Side sleepers with an hourglass figure will want a bit more softness, while a medium to firm pocket unit like this gives back sleepers plenty of support and spreads body weight evenly.

What customers thought

My review would be incomplete without considering what other customers have said about the Luna 4000. Echoing my sentiment, owners mostly describe it as comfortable, and a good few say their sleep has improved since it arrived. One owner summed it up as "So comfortable, the perfect hardness and so good for my back", and another with "slipped discs in back and inflamed hip" said they "do not wake up so achy".

The caveat that comes up most is firmness: one owner called it "Quite firm for medium firm", another found it "harder than expected" before it softened after a month. Temperature splits them. One owner says it keeps a good temperature in summer and winter, while another wrote that "the gel doesn't seem to be working for me". On edges and movement, one owner wrote that "you can sleep right to edge if needed" and that they "don't feel the other half tossing or turning"; another said "There's no disturbing your partner either". Value comes up too, with one owner calling it "really good value for money" and another "Worth every penny".

Not everyone was won over. One owner wanted to swap it but said the trial had already been used, writing "I want to change the mattress but unfortunately I can't because I already had my trial test". Another found the wrapping "very difficult to remove", though they said the mattress was worth the struggle.

The verdict

Between the build of the Luna 4000 Support Gel Memory Pocket Hybrid Mattress and what its owners report, I am confident in endorsing it for those seeking a mix of personalised support, comfort, and longevity. Although I have some scepticism about the effectiveness of mini springs in eradicating motion disturbance and the practicality of handling the removable cover, these are minor compared to the overall benefits. Apprehensions aside, the Luna 4000 is a fine example of a mattress 'doing it right' for the money.

It is as it suggests, a supportive cocoon whose purpose is to make your night's sleep as peaceful as possible. Despite some minor criticisms, it's clear that the Luna 4000 has found its sweet spot, delivering on comfort, support and ergonomically designed features all in one package. With its medium level of firmness, it will best accommodate both side and back sleepers equitably. It's a sleeping experience you wouldn't want to miss out on.

Suitability

  • Back Sleepers 4.5/5
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers 4/5
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers 4.5/5
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.

Performance

  • Breathability 3.5/5
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress 4/5
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability 4.5/5
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.

Odour

  • Initial Odour 4.5/5
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour 5/5
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

Brand Rating

  • Overall Brand Rating 4.5/5
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

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.

For the last decade we have been sleeping on a Sealy Orthopedic mattress supposedly expensive because it is good for your posture etc. I am now waking up with far fewer aches and it is bliss, wonderful mattress, we both sleep like logs and are glad we also got two more for our guest rooms.

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.
