Simba Hybrid Mattress Review: Quick Summary

After spending more time in bed during the long lockdown days, we were unsure if the lumps and bumps stopping us from sleeping were due to our mattress or the slats under our bed.

Therefore, when we were given the opportunity to review the Simba Hybrid Mattress, we thought it was the perfect chance to get to the bottom of it once and for all.

After a week of sleeping on the Simba Hybrid, we had our answer, the lumps and bumps were definitely our old mattress. The Simba eradicated all the issues we'd previously experienced, and we had the best nights sleep we'd had in years.

Simba Hybrid Mattress Review: Unboxing and First Impressions

Simba provided us with an allocated delivery time slot and sent us regular text updates, which made the arrival of the mattress easy to organise.

Although be warned, a boxed mattress is pretty heavy when it arrives, so you may need to enlist a friend/partner/Sherpa to get it up the stairs.

The instructions were clear and easy to follow which made the unboxing process pain-free and the plastic cutter made it very straightforward to remove the packaging.

Within minutes of the mattress being free from the box and its wrapping, we could see the mattress start to expand and take shape. It took around 3 hours to develop enough to be slept on and around 24 hours to expand fully. Simba recommends waiting 3-6 hours to sleep on your mattress and says it can take 72 hours for it to expand fully.

When putting the sheets on the bed we noticed that the mattress was a lot thicker than our previous one. Though our regular sheets did fit (snugly), we decided to purchase deep-fitted sheets to ensure a more comfortable fit.

Our bed is pushed against the wall, which made fitting the sheets tricky and really highlighted the weight of the mattress. We struggled to lift the corners by ourselves, which might be worth keeping in mind if you live (or fit sheets) alone. However, if your bed is in the middle of the room, or you can easily access 3-4 sides of the bed, we imagine this wouldn't be an issue.

As mentioned in the instructions the mattress gave off a plasticky smell when it was first unpackaged. We weren't too bothered by it though and it disappeared within a few days.

Simba Hybrid Mattress Review: Performance

We'd previously heard that a new mattress can take a week or two to get used to, but not for us, we slept amazingly the first night we tried the Simba Hybrid.

Despite being a bit firmer than we were used to, it was such a huge step up from the last mattress that we barely even noticed. We found it comfortable, supportive and the firmness softened after about a week.

The Simba Hybrid mattress is made up of five layers – a breathable sleep surface, a layer of open-cell Simba-pure (Simba-pure= TCPP-free foam), a layer of patented Aerocoil springs, another layer of Simba-pure with edge support and a Simba-pure support base.

The patented titanium Aerocoil springs and breathable sleep surface are designed to keep you cool, and we noticed a difference between the heat of our former memory foam mattress and our Simba.

Though we rarely got too hot when sleeping on our Simba Hybrid mattress, if overheating is a big issue for you it might be worth considering the Simba Pro or Luxe mattresses which incorporate even more advanced temperature control and cooling technology.

How much is a Simba Hybrid mattress?

Prices for the Simba Hybrid mattress start at £349 for a kids size and go up to £1009 for a super king.

There are 9 different mattress sizes to choose from, which is far more than most bed-in-a-box companies offer. The sizes and prices are as follows:

Kids (W90, L190, D16 cm): £349
Single (W90, L190, D25 cm): £589
EU Single (W90, L200, D25 cm): £649
Small Double (W120, L190, D25 cm): £799
Double (W135, L190, D25 cm): £799
EU Double (W140, L200, D25 cm): £849
King (W150, L200, D25 cm): £909
EU Queen (W160, L200, D25 cm): £959
Super King (W180, L200, D25 cm): £1009

The original Simba Hybrid is pretty evenly priced to its competitors. Both Eve Sleep's original hybrid mattress and Emma's hybrid cost £769 for a double, just £30 less than the Simba.

If you were to opt for the Simba Hybrid Pro mattress instead, which has temperature regulating layers, you're looking at around £300-350 more for the equivalent size.

And if you were to opt for Simba's newest addition, the Luxe mattress, you'd be looking at around £500-£990 more for the equivalent size.

Simba regularly has discounts on its mattresses, so it's worth keeping an eye out for a deal. There is currently up to 35% off Simba mattresses – the same discount they offered during Black Friday last year – but the deals ends at 11.59pm on July 31st (so be quick!).

How thick is the original Simba mattress?

The Simba Hybrid mattress is 25cm thick for all sizes, except for the kid's size which is 16cm deep.

It's thinner than both the Pro mattress which is 28cm thick and the Luxe mattress which is 31cm thick, due to their extra layers.

Although a standard fitted sheet should fit your mattress, you may find (like we did), that a deeper sheet fits more comfortably.

Is a Simba hybrid mattress good for back pain?

We're not medical experts and therefore can't provide you with any concrete evidence of Simba mattresses helping back pain, nor do we have any first-hand experience to share.

However, at the time of writing there are over 14,000 reviews of the Simba Hybrid mattress which state that it has "significantly improved" back pain.

One review reads, "I’ve struggled for a while with back pain and done extensive research on the best mattress around, the Simba kept coming up, and without a doubt the best nights sleep I’ve ever had. Highly recommend".

Where are Simba mattresses made?

According to the Simba website, all Simba mattresses made for the UK market are manufactured in the UK. The materials are sourced and made in Europe, though the steel springs are made in Leeds and the wool used in the Simba Pro is British too.

Are Emma and Simba mattresses the same?

No. Emma and Simba are different companies, however, they both sell bed-in-a-box mattresses.

Emma has three mattresses available for purchase at the time of writing – the Emma Original (memory foam), Emma Hybrid and Emma Original Hybrid. Prices for the Emma Hybrid start at £569 for a single and go up to £979 for a super king (which is £30 cheaper than the Simba Hybrid).

We've previously reviewed the Emma Original Hybrid, read it here.

The Verdict: Are Simba mattresses good?

 In our opinion, the Simba Hybrid mattress isn't good, it's excellent.

The mattress has transformed our sleep, and we feel more rested than we have done in years.

We would (and have) recommend this mattress to our close family and friends, especially since the 200-night trial and 10-year guarantee means you can always return it if you don't love it as much as we did.
