What our reviewers found

Pros

One of the more established brands retaining high quality through their decades of experience.

Memory foam is one of the better and more desirable comfort layers.

The 1800 pocket springs are toward the high end when it comes to both quality and density.

Cons

Memory foam can unfortunately sleep a little hot is great for those who like to sink into their comfort layer.

Price point may be a bit of a barrier for those on a budget.

This one should be considered for back sleepers.

If you've ever woken up in the middle of the night and couldn't get comfortable, it's time to ditch your old mattress. The Relyon Memory Plus 1800 Pocket Mattress is rated firm, and with 1000 full-size pocket springs and a further 800 mini springs under the foam I'd say it's aimed at people who want that firmer, more supportive vibe rather than a soft, sink-in feel. With this Relyon Memory Plus 1800 Pocket Mattress, you'll be able to get comfortable in no time at all, and with enhanced orthopaedic support you'll find additional pressure relief helping with unwanted aches and pains.

The Relyon Memory Plus 1800 Pocket Mattress is designed to reduce pressure points and provide a comfortable night's sleep. The cover is a soft-touch knit that's only micro-quilted, so the comfort is coming from the memory foam underneath rather than any big, plush quilting. That foam is a 4.5cm layer, enough for the slow, moulding response memory foam is known for, but over a firm spring unit I wouldn't expect you to get swallowed up by it. The memory foam comfort layer provides pressure relief that rebounds while the pocket sprung support layer provides a firm tension for those who need a little bit more support than average. For back sleepers, a firm unit of individually pocketed springs should keep your hips held up rather than letting them sag, which is what you want if your lower back tends to complain. Side sleeping is where I'd be more wary, because 4.5cm of foam over a firm tension doesn't leave a shoulder much to sink into, so if you're a lighter side sleeper this firmness could come across as a touch too hard. One owner calls it a "nice firm bed all round" and another says it's "not comfortable at all", which is the split I'd expect from a tension this firm. The mattress is 31cm deep, which is perfect for most beds and bed frames, but do double check your fitted sheets because that extra depth can be a pain if you're used to standard 25cm-ish mattresses.

This mattress is perfect for back and stomach sleepers and the listing now shows it in King Size only. Just be aware that memory foam can sleep a bit warmer than a straight spring mattress, and 31cm of mattress isn't the easiest thing to wrestle on your own, though it does have turning handles stitched into the border.

How it scores
of the Relyon Memory Plus 1800 Pocket Mattress
Scored from the build: how this construction usually performs, compared with mattresses of a similar type and price.
Scored from the build: how this construction usually performs, compared with mattresses of a similar type and price.

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 3.5/5
  • 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 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 3.5/5
  • 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.

Ease of Use

  • Turning handles 5/5
  • Mattresses typically need to be rotated frequently and having turning handles can be massively beneficial, particularly in larger sizes which can become fairly heavy.

Odour

  • Initial Odour 4/5
  • 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.
