When it comes to children's mattresses, particularly for bunk beds, it can be particularly difficult to find something suitable for your child. After all, these mattresses are often a sub-range not given much thought by most of the bigger players in the mattress industry. As such, it's a welcome change to see Silentnight at the top of the list for this new and practical Silentnight Foam Bunk Mattress.

Featuring practical advances like being anti-allergy, ideal for those who suffer, this hypoallergenic mattress will be ideal at home in any kids bed or bunk bed. With an impressive Miratex foam to operate as equal parts support and comfort, this should prove adequately comfortable to help the growing bones of young children while offering enough support for the neck and back as they sleep.

The mattresses are made in the UK to strict British guidelines while also featuring an impressive 5 year guarantee to help instill further confidence for those purchasing. Finally, the mattresses come rolled up allowing the logistics and delivery costs that normally increase the markup on a product to be averted and help to ensure that you get a great deal on your investment for your child.

Reasons to Buy

We all know how important it is for children to get a good night's sleep, and that starts with the right mattress. The Silentnight Foam Bunk Mattress, made from Silentnight's Miratex foam, is perfect for bunk beds or small rooms. The slim 14cm depth is lightweight and comes rolled up for moving, with a 5 year guarantee.

Reasons to Avoid

Bunk bed mattresses may be unsuitable for heavier people. This is due to the deliberately thin nature of the materials to ensure they meet proper guidance for bunk beds, preventing people from rolling over the protective sides. The benefit of this is that the mattresses fit perfectly but the downside is that less material and thinner mattresses may see heavier people being a bit too close to the slats beneath to be comfortable.

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews.

Key Performance Indicators KPI question mark

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 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.


  • 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.

What Makes The Silentnight Foam Bunk Mattress Great?

Featuring Silentnight's Miratex foam

Soft knitted cover for added comfort

We really like soft knitted covers as the fabric is incredibly soft and stretchy while also being breathable, helping to keep you cool while ensuring the mattress can breath. The result is a hygienic nights sleep that has you sleeping deeper, improving the quality of your sleep and reducing tossing and turning.

Hypoallergenic, with anti-dust mite properties

Allergy sufferers often experience the problem of waking up in the middle of the night or having to get up in the morning with a stuffy nose and eyes. The reason why you wake up with a stuffy nose is because your mattress has accumulated dust mites, mould and mildew, all of which are allergens. The solution is a hypoallergenic mattress is made from materials that do not support mould or dust mites. They also have anti-microbial properties that effectively kill any bacteria that may come into contact with it.

Firm and supportive

When we fall asleep, our muscles relax and what that does is it allows our body to decompress. But when we're sleeping on a too soft mattress, the muscles don't have enough support and they're not getting the proper relaxation.The benefits of a firm mattress are that you're going to sleep more soundly,  your back pain is going to be relieved and you're going to have less muscle aches and pains.

Single-sided for easy care - no need to turn over

A single sided mattress is typical for the industry and relates to how  a mattress has the comfort layer on one side of the mattress. only This means that the mattress only needs to be rotated rather than flipped. The benefit of single sided mattresses is that they require less upkeep in that there's no flipping, but also, there's less components involved in the creation which saves costs.

Slim 14cm depth - perfect for bunk beds

14cm is slightly thinner than normal for a mattress but still largely sufficient for good quality components to reside. One benefit of this depth of mattress is it is ideal for bunk beds or other limited height bed frames.

Lightweight and comes rolled up for easier moving

Rolled mattresses are delivered in a smaller airtight mode of shipping that saves retailers on shipping, storage and logistics costs that mean they can pass the savings onto consumers in the form of lower prices. The result means that you can often get a similarly specification mattress for less in rolled form which is fantastic news for those on a budget. With very little downside and positive experiences across the industry, there's plenty of great reasons to make your next mattress a rolled bed-in-a-box product.

Depth: 14cm - perfect for bunk beds

14cm is slightly thinner than normal for a mattress but still largely sufficient for good quality components to reside. One benefit of this depth of mattress is it is ideal for bunk beds or other limited height bed frames.

Made in the UK

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.

5 year guarantee

A 5 year guarantee is quite rare in the industry and is a great indicator of the retailer beleiving in their product. Anything go wrong in the next 5 years, no drama, get it replaced.

Reflex foam

Reflex foam is basically like memory foam without the memory part. Reflex foam is used more as a supportive layer than a comfort layer and is often used as an alternative to conventional spring systems.

Knitted Cover

It is common in the industry to have a knitted cover, these covers can come in a variety of patterns but are typically hard wearing and do not present problems for consumers.


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


Firm mattresses are great for those looking for an extra bit of support, either because they have a higher BMI and leanm toward the heavier side, or because they have joint and muscle pain and appreciate a decent amount of support while they sleep. If you are not actively looking for a firm mattress it may be wise to consider something else from the range that is perhaps closer to the medium firmness rating

14cm deep

The industry standard for mattress depth is 7 inches, with most offering a comfortable 10 to 14 inches. Generally, the higher the load, the deeper it needs to be. But quality is important as a well-built 10-inch mattress can be equally as comfortable and supportive as a budget 12-inch mattress. This 5 inch mattress sits at the lower end of the scale, generally for a lighter person this matters is easier to store and Hanover. 


Rolled up mattresses are ideal for anyone looking at trying to get a mattress up a tight staircase or in a car to bring home from the shops. Do not missunderstand just how troublesome getting a mattress up stairs can be. Heavy and cumbersome, sometimes a rolled up mattress that expands to the side of a full mattress anyway, may be the better option


Single sided means only one side is comfy. Positives are you only need to rotate the mattress occassionaly rather than the more cumbersome rotate and flip. Downside is the lifespan of the product may suffer as a result, only marginal, but worth mentioning.


The fabrics, materials and fillings of this mattress are the result of what has been deemed vegan-friendly materials. Ideal for those expressing their beliefs while still requiring good levels of comfort and support from a product

Handcrafted in the UK

Handcrafted in the UK means that the product is built here, by people being paid a fair and honest wage using certified and safe products of good quality and construction. UK manufacturing is some of th best in the world and all of that is reflected in this product

Fire Resistant

Fire resistant does not mean the product will never catch fire, rather, it will not go up in flames quite so quickly. Resistant to fire in the same way that I am resistant to kisses, sooner or later you end up giving in.

Approved by the National Bed Federation

The NBF is one of the most prestigious awarding federations in the industry, helped slightly by the fact that it is one of the only, however, it is still a great source of comfort knowing that this product holds approval by the team

Customer Reviews For The Silentnight Foam Bunk Mattress

Based on 24 reviews

These mattresses seem very comfortable so far. I also find it much easy to change the sheets than on our other bunk beds with sprung mattresses as these ones seem lighter and easier to manipulate to tuck sheets in.


I love how it arrived in a compact cylinder shape ideal for space saving. The mattress is the perfect height for a cabin bed whilst still providing comfort and support where my daughter needs it.


Needed to replace my sons mattress for his bunk bed in a hurry, this bunk mattress fits the bill perfectly. Just the right height and comfort level, most importantly my son is sleeping fine.
