In this Simba Bunk Bed Mattress Review, we will be looking at the slimline mattress from Simba. Simba is a British innovator bedroom brand with its mission being to simplify sleep, using the latest technology and data to make revolutionary products that adapt to your body. In simpler terms, Simba is dedicated to not only changing the way the world sleeps but also how the world thinks about sleep. 

This is why Simba have a single mattress, allowing them to fill the mattress with all of their technologies. Using the same technologies found in the Simba Hybrid, Simba has created a slimline version, suited for kids 3 years and older. Simba also claims that the slimline mattress is suitable for adults who are young at heart.

The Simba Bunk Bed Mattress was specifically designed for use in bunk beds. This hybrid features supportive springs and comfy foam, but we will cover these in more detail when we get to the layers section.

Simba Bunk Bed Mattress Construction

As the Simba Bunk Bed Mattress is made right here in the UK and of course sold here too it has to abide by strict regulations regarding manufacturing. Basically, the entire product and all its materials must be tested and must meet certain criteria which ensure that the product is safe for customers and the environment. 

A hybrid design utilises both the support of springs and the comfort of foams. Variations on this design do exist and more specifically, the number of layers for foam or springs varies per product. This hybrid design features a pocket spring layer and 2 foam layers, which we will explore in detail in the layers section. 

All foams used by Simba receive the CertiPUR Label, which specifies certain substances that may not be used in the manufacturing of polyurethane foams. The label even sets upper limits concerning certain components of the foam that may be of concern to your health or that of the environment. 

The layering used in the Simba Bunk Bed Mattress also helps to create a breathable mattress. This means that air is allowed to circulate freely. The 3 layer design was engineered so that it doesn’t retain moisture, odours or heat.

Simba Bunk Bed Mattress Cover

The Simba Bunk Bed Mattress is wrapped in a knitted PES or polyester material. The use of this material is strategic, as this type of material is easy to clean, retains its shape well and dries very quickly.

Keep in mind the cover is not removable and in terms of cleaning, we would advise that you spot clean the material.

If you are thinking of getting the Simba Bunk Bed Mattress for kids, then we would also suggest that you make use of a mattress protector, as these are removable and washable and will protect your mattress from leaks or spills. If you would like to stick with Simba you can also have a look at the Simba Mattress Protector.

Simba Bunk Bed Mattress Mattress Layers

A hybrid mattress makes use of both springs and foams. In the case of the Simba Bunk Bed Mattress, it makes use of a single spring layer and 2 foam layers of different densities.

1. Foam Layer  

The first layer is a foam layer is a Visco foam. Visco elastic foam is another term for memory foam. It is a blend of polyurethane foam that was developed for aeroplane cushions by a NASA contract in the 1970s.

It is designed to add comfort and has active/ live responsiveness. This means that it reacts to the sleeper as they move. This is an important aspect if the mattress will be used for kids as they tend to move about more than adults. This design will allow them to move without waking them.

2. Core Pocket Spring Layer  

The spring layer consists of 324, 1.8mm thick springs. Each spring was designed to move from front-to-back as well as from side-to-side. The support of this mattress is made to ensure that the head, shoulders, spine and hips are aligned in a proper and healthy position.

Generally speaking pocket sprung mattresses are supported by their springs, in this case, these mini springs aid more in comfort and breathability than anything else.

3. Base Foam Layer 

The bedtime story layer is also a memory foam layer but is specifically added to support the weight of an adult. This layer adds to the no motion transfer property of the mattress. This layer also makes this slimline mattress suitable for adults to sleep on, thanks to the added density.

How Thick is The Mattress?

The Simba Bunk Bed Mattress stands at a total depth of 16cm. If you are thinking of using this mattress in a spare room or for an adult then the weight limit should be noted.

In terms of weight limits, the Simba Bunk Bed Mattress can hold up to 15 stone or 95kgs. Making this a great mattress for kids and light adults not exactly a mattress for heavier people.

Simba Bunk Bed Mattress Mattress Firmness

The Simba Bunk Bed Mattress is rated as a medium feel mattress. Mattress companies typically go for a medium feel mattress as it is ideal for most UK sleepers.

Aesthetics and Design

The Simba Bunk Bed Mattress is finished with the classic bed-in-a-box industry look. Grey sidewalls with a white, knitted top finish. The final detail, which adds a splash of colour, is the Simba logo that is stitched onto the sidewalls. 

The Simba Bunk Bed Mattress can fit in most standard bunk beds and bases in the UK. To be sure that it fits your intended base/ bunk we suggest that you double-check the dimensions of both. 

This bunk bed mattress is designed to fit snugly in a shallow bunk frame for increased safety. The safety regulations for bunk beds seem to be much stricter than that of a normal stand-alone frame.
