Review: Will You Sleep Sounder With A SIMBA Hybrid Mattress?

Have you heard of the SIMBA Hybrid Mattress? Many years ago, mattresses weren’t very sophisticated.  In fact, the choice was basically soft, medium or hard depending on the needs of your back.

Lately, though, you may have noticed a shake-up in the number and types of mattress available – all of which claim that you will have the best night’s sleep ever.

As he’s getting quite tall, Ieuan’s bed frame was replaced a year or so ago. We choose a simple metal frame bed from John Lewis but let Ieuan choose his own mattress.

The staff waited patiently as Ieuan tested about 10 different mattresses several times.  I could have had a large coffee and a muffin plus a tour of the beauty department (never a chore) in the time it took him to settle (literally) on the one he wanted – a SIMBA mattress for his single bed.

Would you believe there’s a double mattress in there?

We hadn’t heard of SIMBA before and assumed that it was a standard memory foam mattress.  We were intrigued when, on delivery, we found that the mattress appeared to be vacuum packed and watched it spring to life when it was cut out of its plastic.

We then had to leave it for 3-5 hours to ‘inflate’ before Ieuan could sleep on it. After we all tested it, we agreed that it was the most comfortable mattress in the house.

So, when I was recently offered the chance to review a SIMBA double mattress, it was a no-brainer and I couldn’t wait for it to arrive.

This time though, I wanted to learn a little more about what was about to turn up.

A SIMBA Hybrid Mattress is far from being just a block of memory foam. It has been specially designed to meet the needs of all body shapes and sizes. The company worked with The Sleep To Live Institute in its extensive and lengthy profiling of over 10 million people.

Although it is only 10 inches thick, the SIMBA Hybrid mattress has 5 unique layers which all have a role to play – the Simba 5Ss.

Simbatex Layer

First up is a soft comforting ​layer that provides support throughout the night. This layer has been developed by SIMBA and contains a synthetic latex layer that also gives a cool feel for the entire time that you lay on it.

Spring Powered Layer

Featuring 2,500 conical unique springs ​which adjust individually through your sleep and react to your movement, this layer ensures that you remain supported throughout the entire night.

The Shaped For You Layer

Constructed using high quality Visco Memory Foam, this layer moulds to the shape of your body and reacts to changes in body temperature and weight so it can sense when you’re lying on it. It springs back into its original shape when you get up.

This memory foam layer also allows you to move naturally in your sleep whilst working to align your spine and promoting healthy posture to relieve tension and pressure.​

Visco Memory Foam is hypoallergenic and anti-microbial so it scores well in the hygiene stakes. It is highly resistant to bacteria, mold, mildew, mites, and other odour causing germs, making it a great choice for those with sensitivities or allergies.

It is also effective at reducing motion transfer, which is invaluable for those who share a bed. If your partner is a restless sleeper, or if your partner gets in and out of bed and disturbs you during the night or in the morning, Visco Foam mattresses minimize this disturbance.

Visco Elastic Foam mattresses also tend to last longer and provide more pressure relief than the more traditional ‘sprung’ mattresses.

Seventh Heaven

This layer is a thick support base which is the foundation for the mattress, and has 7 different load bearing zones to evenly distribute your weight across the mattress.​

Sleep Surface

The entire mattress is encased in a breathable hypoallergenic cover, allowing ​for freshness to be retained and the temperature to be controlled to a consistent level for the whole of your sleep.

The SIMBA Hybrid Mattress can be used on any type of bed base – slatted platform, flat base, divan or adjustable base and comes with a 10 year guarantee.

SIMBA also offer a 100 day trial with a no questions asked pick-up and a refund.

You can order your SIMBA mattress directly from or from John Lewis.

I was sent a SIMBA Hybrid Double Mattress and it arrived vacuum packed and sealed in a box which is much smaller than the mattress!  This means that you don’t have to wrestle with a mattress to get it upstairs – you simply carry the box.

You then take it out of the box, free it from its plastic covering using the handy cutting tool that comes with it and then leave it for between 3-5 hours to expand into its original shape so that it is ready to use.

Your SIMBA needs 3-5 hours before you can sleep on it for the first time.

If you read the customer reviews, you will no doubt find mention of an initial smell but this is normal with memory foam products and it fades in a day or so.

The mattress comes with full instructions and a nice welcome pack in the box which includes the cutter mentioned above.

How Did I Sleep?

Readers know I have been having problems with my back for a while and am coping in the day with pilates and stretching so I had high hopes for my SIMBA.

If you are unused to sleeping on a memory foam mattress, you will find it a new experience. A perusal of the customer reviews on SIMBA’s website shows that whilst the majority took to it like a duck to water, some take just a little longer to get used to it – and I’d put myself in that category.

My previous mattress was a 1400 pocket spring mattress some 10 years old so well overdue for replacement. It had developed a couple of suspicious dips in places which we tried to get over by turning the mattress regularly.

Caitlin found the Simba Hybrid mattress really comfy

Initially I found the SIMBA surprisingly firm but, comparing it with Ieuan’s which is now over a year old, it is easy to see that the mattress softens and moulds to the user over time – and so it is already with mine.

I find that I don’t tend to move about so much in my sleep and once of the surprising results of this was a reduction in nocturnal waking – and the resultant trips to the bathroom.

I also felt a little taller and straighter, although my lower back grumbled for a bit probably at being supported properly for the first time in years.

Now after 3 weeks I am already finding I am looking forward to being reunited with my SIMBA at the end of the day. The mattress is already a little softer and ‘fits’ me better.

I still have a moment of surprise when I sit on it and it doesn’t sink like my old one used to and more often than not these days I sleep through to at least 6 am – whereas I would regularly see 4 am and 5 am.

When you get into bed and lie down you can feel the mattress supporting your back and spine without sinking too far into it.​

For us ladies of a certain age, heat regulation is also pretty important but I found that the SIMBA Hybrid Mattress’ thermo regulation technology works well and even with a duvet and a throw I don’t overheat and become uncomfortable.

​Would I recommend one?  Yes I would and, with SIMBA’s 100 day trial you have absolutely nothing to lose by giving one a try.

Memory foam mattresses are so comfortable and supportive. As a lady of a ‘certain age’ I may have to get one too 🙂


It always amazes me how small the packaging is with these mattresses in size. It looks really comfy


I remember when I bought a mattress and the smell. I agree that it lasts a day or so and that is normal. I never heard of this brand but looks like a good one to try on. Maybe when I needed one again, I will and this and compare with my recent.

Oh that sounds fab, we have a memory foam mattress which has really helped but I need to get better mattresses for my kids. Maybe it would help them sleep better too!

Super Busy Mum

I believe I would, yes! This sounds like an amazing mattress because if anyone needs a good night’s sleep, it’s the parents, right?


Your rabbit is beautiful!! Does he/she sleep on the bed with you like a dog or cats do?


Ive seen those SIMBA mattresses advertised. Im thinking of trying one when i need a new mattress


I just love our memory foam mattress… so comfortable… never slept better


I have never heard of SIMBA mattresses but it seems to be a very nice one. I will give it a try .


Wow this sounds like exactly what I’m needing. My mattress is really supportive but obviously it hasn’t softened around me like this one would.

I hurt my back in the gym this week and being comfy in bed would probably help.

Wow how did it fit in that box!!! This sounds like a really lovely mattress. I need to check if ours needs replacing as this sounds great!

We have just talked about getting a new bed and mattress to aid a more restful nights sleep. Love the fact it comes boxed and expands 🙂 plus it sounds like a high quality one


Love the idea of this. I need a new mattress so will have to check them out x


I’ve heard of these mattresses before and how good they are! I find it bizarre that they have to ‘inflate’ though. Haha. I used to have a memory foam mattress and I loved it, and it’s lovely to sleep on. But I find that memory foam mattresses are more uncomfortable to sit on (I often work on my laptop whilst sat on my bed!) Is that weird? :/


I’ve heard so many good things about SIMBA mattresses that they would probably be my first choice to go to. I will always shop for a decent mattress, as you really need the right support for that perfect night sleep.

I have heard of Simba, but didn’t know how good/not good they were. A good mattress makes all the difference.

My older son has one of these! He loves it and it was fascinating watching it take shape after bringing it home.

This mattress sounds good…. I was looking for a similar kind of mattress. I will buy this one soon… Thanks a lot!
