What our reviewers found

Pros

  • A TrueGel layer under the cut foam, which takes a little of the warmth out of the foam.
  • The distinctive castellated foam design offers enhanced pressure relief and minimises motion transfer, making it an excellent choice for couples.
  • Comprised of 1000 pocket springs that adaptively supports your body, providing a soothing, cushioned sleeping experience regardless of your sleep position.
  • A base of recycled Ecofoam under the springs.
  • A ten-year guarantee, long for a mid-range hybrid.

Cons

  • Single-sided, so you can't turn it, and to my mind a mattress you can turn lasts longer.
  • Heavier sleepers will want a firmer mattress than this medium.

Sleep, they say, is the golden chain that ties our health and bodies together and at the core of a great night's sleep is the right mattress. The importance of this humble bedroom essential cannot be overstated. With soaring expectations of comfort, we look for a mattress that harmoniously ticks the boxes of our personal preferences and health needs. This one is the Komfi GelMed Comfort Mattress, a medium hybrid that puts a gel layer and cut foam over pocket springs.

How we assessed it

The Komfi GelMed Comfort Mattress is a 25cm hybrid: a top layer of castellated foam cut into grid-like sections, Komfi's TrueGel layer, 1000 pocket springs and a base of recycled Ecofoam, all under a micro-quilted cover. It is rated medium, which gives you a cushioned surface with springs working underneath it, so it's easier to turn over on than an all-foam mattress of the same depth. Foam cut into separate sections and springs in their own pockets both keep a partner's movement on their side of the bed. Heat is the part we'd watch. There is foam above and below those springs, and the gel and the gaps cut into the top layer are what is meant to keep it cool. It is single-sided and arrives rolled, so rotate it and don't try to flip it.

Design and features

The idea behind the Komfi GelMed Comfort Mattress resonates with the modern consumer's demand for a blend of tradition and innovation. This mattress parades features that provide comfort, adaptability, and durability. Encased in a sleek Microquilted cover, the mattress has a unique layering of Pocket Springs, TrueGel Technology, and Reflex foam. Komfi sells the TrueGel layer on drawing heat away from you. Gel is the cooling material I'm most inclined to believe in, as a mild benefit rather than a reason to buy. The reflex foam is the part I'd watch over the years, because cheaper reflex foam is what loses its shape first. Regardless, the Reflex Foam promises to mould to your body's contours, maintaining spine alignment and offering a sound sleep.

Mattress comfort

Rated medium, with castellated foam and a gel layer over 1000 pocket springs, it suits side sleepers better than back sleepers, who are better on something a notch firmer. Pocket springs under foam and gel make a comfortable bed, but I'd expect more than that at this price.

Suitability

At 25cm deep it takes standard fitted sheets.

What customers thought

One owner wrote "Very good up to now."

The verdict

After a thorough assessment, our verdict on the Komfi GelMed Comfort Mattress is mixed. It is comfortable and it adapts to your shape. Our concerns are the price for what's inside and how the reflex foam holds up. Buy it if you sleep on your side; back sleepers and heavier sleepers should go firmer.

How it scores
of the Komfi GelMed Comfort 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
  • 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 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 4/5
  • 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.

Odour

  • Initial Odour 3.5/5
  • 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 4.5/5
  • 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.
