The ‘bed in a box’ market has exploded in recent years and there are now more options than ever when it comes to picking a new mattress to be delivered to your door.

The Simba brand has been around for quite a few years and they have quickly established themselves as one of the leaders in the mattress market.

But does the original Simba Mattress live up to the marketing hype or are there other better options available right now?

This Simba Mattress review is going to concentrate on all of the important things you need to know about this particular mattress as we look to see whether it makes it onto our list of the top memory foam mattresses on the market right now.

We’re going to be paying particularly close attention to what it’s made of, how it feels, and what real customers are saying about the Simba.

Picking the right mattress to support a restful night’s sleep is one of the most important decisions you’ll make, as we all know that good sleep is a vital pillar to your overall health and wellbeing.

So, with the introductions out of the way, let’s start taking a close look at the Simba to see how it fares.

Simba Mattress – The Basics

The Simba Mattress is what’s known as a ‘hybrid’ mattress. This simply means that it combines both memory foam and coils to help support a restful night’s sleep.

What sets it apart from other similar mattresses is that this Simba contains a single layer of cone-shaped springs that offer a unique feel different to just standard memory foam.

Taking a look at the marketing material on the official Simba website, this mattress promises to deliver “the best of both worlds” from both a foam and spring mattress.

It claims to offer “cloud like comfort” as well as “cooling airflow” and “the right support”.

It’s particularly good to see that Simba have built this mattress with a particular attention to cooling, as standard memory foam mattresses tend to feel hotter than traditional mattresses.

The marketing material goes on to describe the Simba as “firm but bouncy” and it also claims to suit a wide range of sleepers.

Going back to the cooling issue, the marketing material says that the Simba uses “advanced materials” and a five-layer design to help regulate your temperature no matter the season.

The Simba Mattress comes with free delivery to UK addresses, and you can pay an extra £30 to have your old mattress taken away and recycled at the same time.

The Simba is around 10 inches thick, which is the standard for mattresses in this category.

It also comes with a removable mattress cover which can be machine washed, which is always a nice bonus for mattresses in this category.

Let’s now take a closer look at what the Simba is made of:

1) 5cm of Latex Foam – A cooling comfort layer to help keep you fresh.
2) 2cm Support Foam with Springs – Microcoils encased in foam to cradle your body.
3) 3cm of Memory Foam – Responsive layer to shape to your body.
4) 15cm of Zoned Support Foam – Durable support to offer pressure relief through the night.

The Simba also features a breathable, zip-off washable cover, which is soft to the touch and easy to clean.

So, it all sounds pretty good to us so far, but we prefer to ignore most of the marketing hype and instead focus on the important things, namely what the mattress actually feels like and what real customers are saying about it after sleeping on it for some time.

With that in mind, let’s now move on to the key parts of our Simba Mattress review.

What Does The Simba Mattress Feel Like?

Like most of the mattresses in this category, the Simba Mattress is marketed as a “medium-firm” option.

The Simba comes in at a rating of around 6.2 on the firmness scale, with 10 being the firmest. This makes it a slightly softer version than the industry standard 6.5 for a medium-firm mattress.

There is a good amount of sinkage from the top two layers, but enough support to keep you feeling comfortable all night.

As this is a slightly softer mattress than other similar products, it will probably best suit side sleepers, as back and stomach sleepers tend to prefer slightly firmer mattresses.

As the marketing material says on the official website, we found the Simba to be “firm but bouncy”. The bounce mainly comes from the top three layers, with the denser support foam below providing good stability for the mattress overall.

The Simba also offers good edge support (it still keeps its shape when you move towards one of the edges of the mattress).

The Positives

• Perfect for Side Sleepers – The slightly softer feel of the Simba Mattress makes it perfect for side sleepers. Indeed, there’s a diagram on the official website of a person sinking perfectly into the mattress and not requiring a pillow to support all areas of the body.

• Old Mattress Removal – For an extra fee of £30, Simba will collect and recycle your old mattress. This is not offered by a lot of other companies, and allows you to enjoy one less headache upgrading your mattress.

• Good Edge Support – With some memory foam mattresses, the closer you get to the edge, the less support you feel. Simba have done a good job of combatting this problem with their design.

The Negatives

• May Not Suit Stomach Sleepers – As the Simba has a slightly softer and more responsive feel, it may not be best suited for stomach sleepers, who tend to prefer a firmer option. The same goes for back sleepers.

• Premium Price Tag – The Simba is one of the more expensive bed in a box mattresses out there right now, with a King Size mattress costing £749 including free delivery. A double currently costs £649.

Simba Mattress Reviews

We took a look on to see what real customers were saying about the Simba Mattress.

At the time of writing, it had an average rating of 4.4 out of 5 stars from more than 190 reviews, which is pretty good.

One happy customer said that they “loved” their Simba because it helped to relieve their chronic lower back pain. They said that their only regret was not buying one sooner.

One of the more negative Simba reviews came from somebody who left a two-star review, complaining that it was “very soft” and revealing that they eventually returned it for this reason.

Anything Else To Consider?

It’s worth remembering that the only real way to know whether a mattress will be right for you or not is to try it out for yourself.

This means giving it a go for a number of night to see how you (and your partner) get on. It’s worth noting that Simba offer a 100-night home trial, meaning that you can return it for a refund during that time if you’re not happy with it.

We recommend buying direct from the official website to ensure that you are covered by the trial, as it’s not clear whether it will apply to purchases made on

The other thing worth remembering is that memory foam tends to have a hotter feel to it than traditional mattresses.

True, the Simba does feature a layer of springs, but the bulk of the mattress is still made out of foam, so it’s worth considering that it may feel a tad hot to some people.

Review Conclusion – Final Thoughts

So, that brings us to the end of our Simba Mattress review.

Overall, we have been pretty impressed by this product overall.

It’s a great hybrid memory foam option that offers a softer feel that should be perfect for most side sleepers.

It’s been specifically designed to offer cooling throughout the night as well as solid support and pressure relief.

Overall, it’s a good choice for side sleepers, the only real negatives being the premium price tag and the fact that it probably is not the best option for back and stomach sleepers.
