In our experience, the materials and construction that go into this product can make it suitable for the following people.

What our reviewers found

Pros

  • 1000 Hypnos pocket springs with firmer outer rows and a rod edge, so you can use the bed right to the side.
  • Owners who mention firmness mostly find it the firm side of medium, which suits back sleepers and couples.
  • A sensible spare-room or first-flat bed from a maker that builds well for the money.
  • At 25cm deep it takes ordinary fitted sheets and sits at a normal height.

Cons

  • The plainest model in the range despite the name: fewest springs and synthetic fibres only.
  • One-sided, so you rotate it and can never flip it to spread the wear.
  • Lighter side sleepers may find it firmer than the Medium label suggests and need a topper.
  • The Cawthorne Luxury adds wool, cotton and more springs at the same Medium grade.

Despite the name, the Hypnos Cawthorne Deluxe Mattress is the plainest bed in the Cawthorne range, with the fewest springs listed and no natural fibres. It's still a decent medium mattress from a maker I rate. Buy it for an average-weight side or back sleeper, a spare room or a first proper bed. If you're heavier than about eighteen stone, or you sleep hot and want wool or cotton next to you, buy something else.

The Deluxe is the bottom rung of the Cawthorne range

Inside are 1000 of Hypnos's ReActive pocket springs, with firmer springs in the outer rows and a rod edge to stop the border collapsing. Above them, top down, are Solotex fibres, a layer of Hypnos's eOlus fibres made from recycled material, and a dual density polyester pad, all tufted under a Belgian damask cover. It's 25cm (about 10in) deep and one-sided, so you rotate it rather than flip it.

Set it against its siblings and the name looks cheeky. The Cawthorne Luxury has the same Medium grade with 1400 springs, wool and cotton. Even the Firm Support gets 1200 springs and cotton. A thousand pocket springs is a little light for a double, though they're pocket springs, so it's still a good way to be held up. Check the Luxury's price before you buy this one, and if the gap is small, put the money there.

Medium on the label, a bit firmer in the bedroom

Owners mostly keep it short and happy. When they do talk about firmness, more of them found it firmer than a medium than softer: one found it "a tad firmer than I expected", a side sleeper added a topper to soften it, and an owner in their mid-fifties swapped it for something with more give at the hip and shoulder. A couple of others thought it soft. I believe the owners over the label here, so expect the firm side of medium.

That suits back sleepers and couples. It's also why a lighter side sleeper should go softer. If it's only a touch firm for you, a topper is the right fix, because a topper solves too firm and never solves sagging. One owner with arthritis found the surface too bumpy, which I'd put down to the tufting. Some of the older reviews are for the earlier Hemsworth Deluxe, which on paper was the same bed.

Fibres, not wool, so think about heat

Solotex is sold as breathable, and fibres of any kind sleep cooler than memory foam. I still like a natural fill next to the skin for anyone who runs warm. I'm fussy about what touches my skin anyway, the kind of sleeper a scratchy label bothers. If you run warm, the Luxury's wool and cotton are the better bet.

Avoid it if you're heavy, if you want a mattress you can turn, or if you want the medium grade to settle an argument between two of you. Mattress Online sells the Medium grade as a compromise for couples who like different firmness. In my experience a middle-ground mattress leaves you both slightly unhappy. Two different grades zipped together beats it, so ask whether you can pair two different Cawthorne singles as a zip and link.

What to buy instead

Buy the Cawthorne Luxury if the price is close: same feel on paper, more springs, and wool and cotton on top. Back sleepers who like a firm bed should take the Cawthorne Support. For a spare room on a tight budget, this one will do nicely.

How it scores
of the Hypnos Cawthorne Deluxe Mattress
Scored from the build and owner reviews: each measure starts from how this construction usually performs, then moves with what owners of this mattress report against owners of similar mattresses.
Scored from the build and owner reviews: each measure starts from how this construction usually performs, then moves with what owners of this mattress report against owners of similar mattresses.

Suitability

  • Back Sleepers 4/5
  • 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 4.5/5
  • 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
  • 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 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 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
  • 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 4.5/5
  • 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.

Good quality, feels comfortable. A tad firmer than I expected but my partner thinks it's perfect. It doesn't sag on the edges, even when you sit up in bed, like our previous one.

Started off with medium to firm mattress. Seemed ok in showroom but when sleeping on it I found it a little too firm. Went back to showroom and tried the medium mattress, this time changed manufacturer to Hypnos. Noticeable difference to the better and agreed the exchange. I have now had the mattress for several weeks and find it very comfortable. I am pleased with the Hypnos mattress and would recommend the showroom in Doncaster for their friendly and knowledgeable service .

We ordered the Firm mattress which gives great support but would wake up with numb limbs. We then exchanged for the Medium mattress which is still quite firm. Great support excellent quality just a very firm mattress. Unable to exchange now as only one exchange aloud. We have purchased a Panda mattress topper which has helped. Personally buying again I'd recommend trying first

Perfect comfort for me - not too firm and not too soft. I sleep on my side so need good support without causing aches by the morning. MattressOnline took the pain out of the selection, buying and delivery process. I visited their store, tried out several mattresses and this selection was delvered the next day. Very happy with the product and process.

I had a Hypnos medium mattress. I can see that some people would find this a very comfortable mattress but for me, it was just a bit too firm. I'm in my mid fifties and find that now I need a softer bed that cushions my hips and shoulders more. I exchanged it for a Millbrook Wool Luxury 3000 which I am very happy with.

Questions and answers about the Hypnos Cawthorne Deluxe Mattress

Common questions answered by our team first, then questions shoppers asked the retailer, with the retailer’s own answers.

Image of the post author
Common question
Is the Deluxe the top of the Cawthorne range?

Answer: No, despite the name, because it has the least inside. The Deluxe uses 1000 pocket springs and synthetic fibres only, Solotex and recycled eOlus over a polyester pad. The Cawthorne Luxury has 1400 springs plus wool and cotton; the Support has 1200 springs with cotton. On the spec the Deluxe sits at the bottom of the range, so compare the prices before you choose, because the Luxury is not always much dearer.
Image of the post author
Common question
Do I need to turn the Cawthorne Deluxe?

Answer: You can't turn it, because it's single-sided. Rotate it head to foot every season instead, so you aren't always lying on the same patch of springs and fibres. It's 25cm deep, which most people can rotate on their own in the smaller sizes, though a king or superking is easier with two. If you'd rather have a mattress you can flip as well, look for a double-sided Hypnos.
Image of the post author
Common question
Is the Hypnos Cawthorne Deluxe good for side sleepers?

Answer: For an average-weight side sleeper, mostly yes: it's graded Medium and the pocket springs let your shoulder in a little. Owners who mention firmness tend to find it the firm side of medium, though, so a lighter side sleeper may want more give than it has. A topper fixes a bed that's slightly too firm. If you know you like to sink in, start with something softer.
