The Simba mattress uses a 4-layer construction hybrid, meaning it uses foams and coils. Memory foam, microcoils, latex foam and support foam all work together to create the total 25cm thickness.

  • Top layer (cooling / comfort) – 5cm of latex foam. This layer provides initial cooling, comfort and bounce to the mattress.
  • 2nd layer (contour) – 2cm of foam-encased microcoils. This layer of microcoils provides some additional bounce. In addition, the coils give a nice degree of body contouring. The foam encasement not only provides protection for the coils, but also a good bit of edge support.
  • 3rd layer (support) – 3cm of memory foam. This layer provides nice support, deep compression and pressure relief.
  • Bottom layer (foundation) – 15cm of support foam. This layer is the stable foundation which supports the above layers and helps the mattress retain its shape.

The Eve mattress uses a 3-layer construction of different foams. There is a blend of memory foam, latex foam and support foam which build up the 24cm thickness. Unlike the Simba, Eve does not use microcoils.

  • Top layer (comfort) – 4cm of memory foam. This layer provides that initial comfort and contouring feel, as well as bit of a slower response time.
  • Middle layer (support / pressure relief) – 3.5cm of polyurethane foam. This layer gives a nice level of support and pressure relief. The poly foam also helps to provide a little cooling, in contrast to the top layer memory foam (which may sleep a little warm for heavier sleepers.)
  • Bottom layer (foundation) – A 16.5cm high-density support foam base layer. This base foam is much denser than the foams above. Its main objective is to keep the mattress’ structure as well as support the foam layers above.

Using 100% polyester, the Simba mattress cover is very sleek, modern, and with a good degree of stretch. It is thin and showcases a nice contrast between the white top cover and gray side panels. This cover is breathable, responsive, and sleeps very cool. The texture of this cover is relatively flat and has somewhat of a knit look to it. The solid gray cording around the top edge of this cover adds a nice detail as well.

The cover of the Eve mattress is 100% polyester as well, so it’s also got a good bit of stretch, softness and breathability. The top cover is white with a grid stitching to create a subtle tactile look. The top cover is also removable by a zipper on the side. The side panels are a stiffer fabric and bright yellow. Although great for branding, this does create a very bold mattress for a bedroom. In addition, if you have thinner sheets, this yellow color may show through the bedding.

Firmness, Feel, & Support

The Simba mattress has about a 6 out of 10 feel on the firmness scale, where 10 is the most firm. This hits a nice range of sleepers who aren’t looking for anything too firm or too soft.

Simba’s use of hybrid foams provides a nice balanced feel to this mattress. The latex foam and memory foam do a nice job of working together- the latex foam providing good bounce and responsiveness, while the memory foam limits motion transfer, provides hug and body contouring.

Between the foams, the microcoil layer helps to make a smoother transition between these two very different feels. These coils help prevent the sleeper from sinking too far into the memory foam, as well as keeping that fast response time.

Overall, the feel of the Simba is supportive, with good bounce, limited motion transfer, and sufficient cooling for very comfortable sleeping. I would recommend this mattress most for side or back sleepers.

When sleeping on my stomach, I found the support to be a bit lacking. After 10 mins or so, the sinkage was so much that it became uncomfortable for my back. That said, I am a lighter sleeper so that may be a factor here (I only weigh about 10 stones). Heavier sleepers may find that they sink more evenly into the Simba mattress so it’s not an issue. Cooling was also very nice with the breathable cover and the top layer latex foam.

For sleepers looking for something just slightly firmer than the a classic medium feel, the Eve hits that point with a mattress that is 6.5-7 out of 10 on the firmness scale, where 10 is the most firm. Because Eve is slightly firmer than a medium firmness mattress, there is going to also be slightly less hug and sinkage.

In terms of feel, the Eve mattress still offers that very balanced feel from the combined use of poly foam and memory foam. It has excellent support, good edge support (from the firmer feel), cooling, an average amount of bounce, and somewhat of a delayed sinkage. I’d recommend the Eve mattress for all types of sleepers. Although it is poly foam and memory foam, the firmer feel helps to provide the support stomach sleepers need to stay comfortable.

The use of poly foam helps the Eve to sleep cool with the top layer of memory foam. The delayed sinkage in this mattress was a little unexpected. Despite Eve’s use of memory foam as the top layer, the secondary poly foam has a way of delaying the sinkage when you lie on the mattress. Fully “sunk”, I still only had about 4cm of averaged sinkage when on my back.

Should I buy the Simba or Eve mattress?

So you’ve heard both sides, but the question remains—should you buy the Simba or Eve mattress? In this mattress battle, we’re going to call it a draw. Both of these mattresses are evenly matched and made of good quality materials, but the feel is just a little different. There is no right or wrong answer for how a mattress should feel.

In short, if you’re looking for a hybrid feel, with more bounce and response that sleeps cooler, go with Simba. For a slightly firmer feel that has a bit more contour and an all-foam construction, go with Eve.

I would recommend the Simba mattress to sleepers who:

  • Want a medium to medium firm feel – The Simba mattress is a 6 out of 10 where 10 is the most firm.
  • Want a hybrid mattress – This mattress is a hybrid construction, meaning it uses foam and coils (in this case, they’re microcoils). The foam support layer at the bottom helps to even out the mattress and you really get a nice blend of materials here. The foam top layer provides comfort and cooling, while the microcoil layer below helps to provide the body contouring. I would especially recommend this mattress for side or back sleepers.
  • Want above average response time – Because of the latex foam used on the top layer, the Simba mattress has a slightly faster response time. It’s by no means instantaneous, due to the memory foam third layer, but it’s still fairly quick.
  • Want good edge support – The extra bit of support foam around the perimeter provides nice edge support for the Simba mattress.

I would recommend the Eve mattress to sleepers who:

  • Want a medium firm to slightly firm feel – For sleepers looking for a medium to slightly firm feel, the Eve mattress may be a better fit, coming in at 6.5-7 out of 10 on the firmness scale.
  • Want a balanced feel – Due to the combination of memory foam and poly foam, the Eve mattress has a nice balanced feel. Many memory foam mattresses are known for their excessive sinkage and hug, but this mattress is able to provide it without enveloping the sleeper. The slightly firmer feel provides a nice level of pushback, keeping you from sinking too far into the foam.
  • Want an all foam design – the Eve uses all foam construction, this gives it more of a classic foam feel, especially with respect to how it contours to the body.
