Key Performance Indicators

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews. For example, a firm pocket spring support layer is more breathable and offers better back support but may prove unsuitable for side sleepers, the reverse is true for a soft-medium tension reflex foam support layer. This is one of 100+ datapoints considered when generating the below ratings.


*Assuming average weight, suitability will vary dependant on body type, use the wizard 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.

What Makes The Sleep Tight 60 x 120cm Pocket Sprung Cot Mattress Great?

Rotate Regularly - Rotate head to toe weekly for the first three months, then every month thereafter

Your mattress should be rotated on a regular basis as this is the easiest way to prolong and increase the longevity of your mattress. The main benefits to regularly rotating your mattress is the continued support and comfort while reducing any risk of sagging that may otherwise occur


This product is unlikely to cause any sort of allergic reaction. Ideal if you suffer from any sort of allergy problems

Removable and washable cover at 60°C

The benefit of being removable is that you are not stuck with unsightly stains that you cannot get out of your mattress. Cat being sick on the mattress? No dramas, throw it in the washing.

Hypoallergenic qualities for the most sensitive skins

The materials used in this mattress are combined to create a product that is unlikely to cause an allergic reaction

PVC Free

Commonly a specification found in Air-Mattresses and can be toxic, as it’s quite common for PVC to cause irritation to the eyes, nose and throat, and also cause headaches and nausea. That's why this mattress has been made free of any PVC ensuring that those that do suffer from the aforementioned when confronted with PVC can still get a sound nights sleep.

Supportive pocket spring mattress combined with anti-allergy fabric

Pocket Spring is one of the better spring systems used in mattresses. Offering a much better level of support than foam or open coil springs, this sort of mattress will last for a fairly long time while ensuring you stay comfortable and supported.

Available in both cot and toddler sizes

Happy little boy with his new mattress!

Great first mattress for toddler moving up from cot to toddler bed, with the added benefit of washable cover and waterproof beneath the cover. It fits his dinosaur bed perfectly and he slept better than before so didnt want to get in with mum and dad. Finally!!

Great mattress

I bought this mattress for my 10 months old baby as we were upgrading to a bigger cot and it's amazing! Seems like a very good quality and the fact that I can take the upper cover off and wash it it's just a dream come through. Very happy.

Washable Cover

Really durable product so far. My kids love jumping on their beds and seems sturdy so far, has kept its shape. Pleased so far! Love the removable cover too which ensure no fluids are seeped into the mattress! It dries super quick too
