Why our sleep experts loved it

Step into a realm of unparalleled comfort and support with the TEMPUR ONE Firm Mattress. This mattress is not just a sleeping surface; it's a technological marvel designed to adapt to your body's unique contours, offering a sleep experience that feels as if it was tailored just for you.


The TEMPUR ONE Firm Mattress is a masterpiece of engineering, featuring original TEMPUR® memory foam as its core material. This visco-elastic foam is complemented by a TEMPUR® Support Material cover, enhancing the mattress's firm comfort level. The mattress is single-sided, meaning you won't have to flip it—just rotate it occasionally for even wear. It has a depth of 20cm and comes with a removable, machine-washable cover.

Benefits of the Materials Used

The original TEMPUR® memory foam used in this mattress is a product of NASA technology, designed to offer adaptive comfort that minimizes motion transfer. The foam's visco-elastic cells adapt to your body shape, offering full-body support. The breathable fabric cover adds to the mattress's ventilation, ensuring a cool and comfortable sleep.

Who the Product Might Suit

If you're a back sleeper looking for a mattress that offers firm support without compromising on comfort, this is the mattress for you. Its firm tension is particularly beneficial for those of average to heavier build.

Who the Product Won't Suit

Side sleepers might find this mattress a bit too firm for their liking. Also, if you're on a budget, the high price point could be a barrier.

Tension suitability

The mattress has a firm tension, making it ideal for back sleepers. It provides excellent lumbar support and helps in maintaining spinal alignment. However, it may not be suitable for side sleepers who usually require a softer surface for shoulder and hip comfort.

About the brand

TEMPUR is a brand that has been recognised by NASA and certified by the Space Foundation. They are pioneers in the field of sleep technology, offering mattresses that are much more than just memory foam. Their products are made in Denmark and come with a 10-year guarantee.

Final thoughts

The TEMPUR ONE Firm Mattress is an investment in quality sleep. Its firm tension is excellent for back sleepers, and the NASA recogniSed technology ensures adaptive comfort. While the price point is on the higher side, the 60-night sleep trial and 10-year guarantee make it a risk-free investment. If you're looking for a mattress that offers both support and comfort, this could be the 'one' for you.

*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • Back Sleepers
  • 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
  • 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
  • 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.


  • Breathability
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress
  • 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
  • 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.


  • Initial Odour
  • 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
  • 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
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.
