The Simba Hybrid Mattress Review - Is It Any Good For Your Back? 

The Simba mattress is a hybrid mattress that aims to give you a supportive and comfortable night's sleep. But is it any good for your back? Find out here. 

Simba hybrid mattress review

You've probably seen the adverts on TV and around the web from the new wave of 'mattress in a box' companies right? 

And whether it's the Eve, Casper, Leesa, or Simba.....there are a fair few to choose from. 

But the thought of buying a mattress this way may not sit right with some. 

Because it seems so very different from the traditional way of doing mattress shopping at your local department store. ​

However, personally I think it's a big improvement in the way we find and buy a new mattress for a couple of reasons. 

Firstly, these companies put all their focus into designing one mattress rather than an entire range. 

This means that all their research and resources are given to making that one mattress as perfect as it can be. 

And you also get more bang for your buck. ​

As these mattresses are significantly cheaper because you are ordering them direct and cutting out the middleman and store overheads.

Plus it's so much less hassle.

As you can browse and order online, your mattress gets delivered directly to your door, and all you need to do is put it on your bed and you're good to go.

So no more long hours spent trudging around department store after department store getting more and more stressed and confused by the endless options.

Then when you've finally made a choice, struggling to tie it onto the roof rack of your car or van to drive it home. 

And don't mention trying to get it up the stairs and into your bedroom!​

So why not cut out this whole process by ordering from one of the new mattress companies instead.

As they all offer a 100-night free trial period, so you can really road test your mattress to make sure it's right for you before committing to such a big purchase.

And for me the Simba Hybrid mattress is the best of the bunch.

But is it good for people like us with chronic back pain?

Let's find out.

What's In The Layers?

The Simba mattress is made up of 5 different layers combining new generation foams and canonical pocket springs.

And they all work together to compliment each other and give you a comfortable and supportive night's sleep.

Top Layer - The Sleep Surface

The sleep surface is what you come into direct contact with as you lay your body down to sleep at night, so it's an important thing to get right.

And Simba do this well.

As it's designed in such a way that it allows the mattress to breathe and for air to pass through it.

This keeps you cool as you sleep and regulates your body temperature, rather than making you hot as other memory foam mattresses can do.

The only downside here is that this top layer can't be removed to be washed.

Although it is easy to spot clean by using a soft, damp cloth, so this isn't really such a problem.

2nd Layer - Simbatex Foam

The layer of Simbatex foam underneath the sleep surface is primarily for your comfort.

But at 4cm thick and with a density of 60kg/m3 it also offers the first layer of support too.

And it helps to keep you cool at night by drawing your body heat downwards and away from the surface.

Middle Layer - Canonical Pocket Springs

The canonical pocket springs are where the main support from this mattress comes from, and this is what makes up the middle layer.

And there are 2,500 of these springs in total, with each being 20mm high.

They each work independently by moving horizontally and vertically to adapt to every small movement your body makes as you shift position while sleeping. 

Which is great for keeping your back and body in a healthy alignment during the night.

4th Layer - Visco Memory Foam

This memory foam layer (3.5cm thick, density of 50kg/m3) is what makes the Simba mattress so comfortable.

Because it moulds perfectly to your own body shape as you lay on it allowing you to feel almost weightless.

And it's responsive all over too so it won't sag over time or in places you don't want it too.

Which means two people of different weights and sizes can sleep on the Simba without affecting one another.

Bottom Layer - Support Base

The base layer (15cm thick, density of 33kg/m3) is what allows the other layers of the mattress to perform so well.

And the extensive testing and research that Simba carries out is evident here.

As there are 7 different support layers to cater for the different demands your body places on different parts of the mattress.

Which is great for keeping your body weight evenly distributed as you sleep and taking the pressure off your body.

So, Is It Good For Your Back?

If you need to find a way to stop every morning beginning like this, then the Simba mattress could be the way to do it.

Ok, so now we get to the crux of the matter.

Will sleeping on a Simba mattress help to reduce your back pain?​

As always the answer to this question is subjective because everyone's body is different.

But what I will say is that the Simba Hybrid mattress has a hell of a lot going for it in this respect.​

Firstly, it's a medium-firm mattress.

And this has been shown in scientific studies to ​be the best overall firmness for providing support for people with chronic back pain.

Also the extensive research and testing that Simba do has resulted in a combination of layers of different materials that all compliment each other well in terms of providing you with great support.

The main area of support is the middle layer which contains 2,500 canonical pocket springs.

As these springs individually adapt to each movement and really help to keep your spine and body in a good alignment as you sleep.

Which will improve your sleeping posture whatever position you like to sleep in and take the pressure off your back and joints.

Also the push back of the springs is a great pressure relieving and supportive feature for your back, and one which elevates the Simba mattress above others that rely purely on a combination of foams. 

And the foam layers included in this mattress also have a good density ratio, so they will help to give your back support too.

Finally, the 7 different support zones of the base layer are excellent for spreading out the pressure evenly and reducing the strain on your body.

So, all in all I think the Simba is a great choice for keeping your back well supported and healthy as you sleep.

Is It Comfortable Too?

Could your new Simba mattress make you as comfortable as this guy?

It's pointless buying a mattress that is great for your back if it's too uncomfortable to get a good night's sleep in.

Fortunately the Simba isn't lacking in the comfort department either.

As the visco memory foam layer really molds to the contours of your body, giving you a relaxing and weightless feel.

Which is great for relieving the pressure on your muscles and joints, especially in your hips and shoulders.

Plus it will cut down on the amount of tossing and turning you do throughout the night, as you can get relaxed and comfortable in one position.

The top two layers are also designed to be breathable, which will help to regulate your body temperature as you sleep and stop you from overheating.

And as being too hot is a big problem with some memory foam mattresses, this is a good feature of the design with the Simba mattress.

However, it can still feel a bit hot compared to a latex mattress, so beware if you've never tried sleeping on memory foam before.

Also the firmness of this mattress may not feel too comfortable at first if you are used to sleeping on a softer one.

But it's this firmness that provides you with the support your back needs (and it's only medium-firm too, not rock hard).

So while this may take a bit of adapting to some people, many say that they get a really comfortable night's sleep once they get used to it.

And finally, being a synthetic mattress the Simba can give off a chemical odour at first which some may find unpleasant.

However this will fade within a few days at the most.

Personal Disclosure

While the Simba Hybrid mattress is a very comfortable one to sleep on, I have to say here that it wasn't the right fit for me personally.

This is because I can't sleep on any mattress or mattress topper that is made with memory foam, as the weightless feeling it gives me causes me pain in my back.

In fact, I've found that I have to stick with spring mattresses to stay comfortable and pain-free.

​So this is something to consider if your back has had a similar reaction to sleeping on memory foam in the past.

However, don't let that put you off otherwise, as I'm in the big minority here.

As most people with back pain that try the Simba give it glowing reviews.

Some Other Cool Features

Here are some of the other features of the Simba mattress that may appeal to you.

Extensive Testing & Refinement

Simba like to market their mattress as the most advanced in the world.

And while that is a bold claim, you can understand where they are coming from when you see how much research and testing has gone into designing it.

As working with the Live To Sleep Institute they have tested over 10 million people and 180 million body profiles to create a mattress that can fit any individual.

And by doing this they came up with a combination of foams and pocket springs that had been unheard of in mattress design before.

But Simba don't rest on their laurels either.

As they are constantly testing and refining their mattress, so you can be sure you are getting the latest up-to-date technology when you order yours.

100-Night Free Trial

Finding the right mattress can be a difficult, frustrating, and stressful experience.

Because there are so many different options out there that it can be hard to know which one will suit you best.

And for such a big purchase you can't afford to get it wrong.

Which is why I love the 100-night free trial that comes with the Simba Hybrid mattress.

As it means you basically get 3 months to sleep on it every night in the comfort of your own home before committing to buying it.

So you can order a Simba mattress free from any worry about whether you are making the right decision or not.

Plus it'll get delivered directly to your front door and collected again if you do decide to return it.

Hassle-free mattress shopping indeed.

10-Year Warranty

And if the 100-night free trial wasn't enough, you also get a 10-year warranty with every Simba mattress if you decide to keep it.

So basically, if your mattress goes wrong within 10 years Simba will collect it and send you a new one.

Which can't be a bad thing and shows the confidence they have in the durability and quality of their product.

Simba Are An Ethical Company

If you're like me and like companies that think about the environment around them and give a bit back rather than focusing purely on profits, then you'll like Simba Sleep.

As they remain environmentally conscious during the production and delivery of their mattresses, keeping pollution down to a minimum.

And if you do decide to return your mattress, rather than reselling it they will donate it to a local charity instead.

Pretty cool right?

It's Good For Other Bedroom Activities Too!

Hopefully you'll be doing more in the bedroom than just sleeping.

So when buying a new mattress you also need to take into consideration whether it can stand up to any extra-curricular nocturnal activities you may be lucky enough to participate in.

And fortunately the Simba mattress can.​

As it has been extensively tested and refined so that it can hold it's shape ​well even under the most testing of circumstances.

So you can feel free to let loose in the bedroom without worrying about damaging your new mattress.

The Back On Site Verdict

So is the Simba Hybrid mattress a good option for people with back pain?

Overall, I'd say that it definitely is.

As the medium-firmness of the mattress is perfect for keeping your back healthy and happy.

Plus the 5 layers that make up the Simba all work well to keep you supported and to relieve pressure on your muscles and joints as you sleep.

Added to that, the memory foam will keep you comfortable too without making you too hot.

So you have a great chance of getting a good night's sleep, which is when your body heals, repairs, and restores itself.

All in all a great and affordable choice.

And with the 100-day free trial and a 10-year warranty you have nothing to lose by giving the Simba Hybrid mattress a try.

Your back may just thank you for it.
