Why our sleep experts loved it

You spend a third of your life sleeping. Why not do it in the most comfortable way possible? The three layers of high-quality materials that make up the Silentnight Eco Breathe Ultra 1800 Mattress offer the perfect balance of comfort and support for a deep, relaxing sleep.

For those unaware, Silentnight is one of the biggest manufacturers in the entire bedding sector producing everything from mattresses, bed frames, pillow and sheets. they have thousands of happy customers every month and have been operating a comfortable amount of time to inspire further trust.

Breaking down the Silentnight Eco Breathe Ultra 1800 Mattress into its different layers we will start by dissecting the comfort layer that sits on top. In the case this mattress, that layer comes in the form of horizontally designed eco comfort fibres which are very efficient at moisture wicking and cooling effects while also helping the environment through the reuse of materials. The Eco Comfort layers are traditionally made up of around 1000 plastic bottles. Fear not though, the comfort layer is far more comfortable and since been woven into an efficient and soft material that acts as a cost effective and efficient layer.

Moving further down the layers you approach the upper spring unit. This is something you don't typically get with mattresses and a relatively new design. effectively you get twice the layers of springs with this layer being made up of 1000 mini springs that will contour and react to every movement your body makes. This layer by itself would likely not be an efficient support by itself however, just beneath this layer you get 800 full height zoned mirapocket springs. These do most of the heavy lifting and kick into action when you roll over or sleep on your side, digging into the mattress with your hip and shoulders. The mini springs are reactive to small movements while the deeper ones below react to larger movements. The combination of both has an interesting effect, proving to be both soft and bouncy while also offering sufficient support for the back and neck. 

This is one of those mattresses that we've been able to try personally and I found the medium tension to be nice and supportive to my body, offering a great combination of the soft comfort necessary to match the support. While I didn't trial it long enough to take particular note of the eco breathes wicking qualities, I did find that I was kept cool and the mattress felt airy.

Quantitative Measurements KPI question mark

Here's how the product performs based on the materials and composition when compared to other products of similar price point. These measurements are produced using a combination of specification-heavy algorithmic data points and our own hands on experience.


*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.

I've heard about Mirapocket springs but never tried them. How do they contribute to the comfort of this mattress?

While the material specifics aren't provided, the mattress focuses on breathability and moisture control, which can be beneficial for people with allergies. However, if you have specific material allergies, it's advisable to consult the manufacturer for detailed information.

I live in a hot climate. Will the breathability features actually make a difference?
