How we tested the Simba Hybrid Kids Mattress

I’m a seasoned mattress reviewer, but had to enlist my 11-year old sister for this review[/caption]
Hybrid Kids Mattress, £349 from Simba
As a self-proclaimed prince of sleep, I am well-versed in mattress testing, but this occasion called for a more youthful tester — so I had my 11-year-old sister put the Simba Kids Mattress to the test.
The girl LOVES to sleep and we deemed her the perfect candidate for the job.
She’s small for her age and is also hypermobile, so sometimes her joints and ligaments can get a little stressed out, making rest extremely important for her.
After the first few days of testing, a newsworthy quote from her was “It’s like sleeping in mummy and daddy’s bed”.
Our parents sleep on a £3,000 Tempur mattress, so we were off to a flying start.
Simba Hybrid Kid’s Mattress review: Quickfire Q&A
Who is it designed for? “Sleepers aged three and up”, according to Simba. For children under three, the brand has a separate Hybrid Cot Bed Mattress.
How much is the Simba Kids Mattress? £349 — or, in other words, a lot for a child’s mattress. However, you could make the argument that it represents a long-term investment in a child’s sleep quality during crucial developmental years.
What we loved: Its slim profile is a standout feature, making it ideal for bunk beds or compact frames. The removable and washable cover is a practical touch, catering to the inevitability of spills and messes.
What we didn’t: The mattress is notably slim, which initially raised concerns about its comfort and durability, though it proved supportive once fully inflated. For lighter children, the firmness might feel slightly hard at first, though this could improve with regular use.
Our verdict: Overall, the Simba Hybrid Kids Mattress is a strong contender for families prioritising quality sleep, though its slim design and price may not suit everyone.
Simba Kid’s Mattress review: The Nitty Gritty
First impressions

The mattress arrived neatly packed and on-time[/caption]

Boring stuff first — the Simba Kids Hybrid Mattress arrived on time, within the one-hour delivery window.
Simba packed it well in a recyclable cardboard box. It’s also vacuum-sealed, making the box surprisingly easy to carry. I was able to drag it to the second floor of the house with little effort.
Once I took the mattress out of the plastic wrapper, it started rising, though it rose slower than other Simba mattresses we have tried.
Simba states that it takes 6 hours to fully reflate and will be in its final shape after 72 hours.
My first impressions were tainted with a slight worry — this mattress is very slim. It looks more like a luxury mattress topper.
I started to doubt how comfortable a mattress could be when it’s so thin.

I was slightly concerned at how slim the mattress is, even when fully inflated[/caption]
It reached full depth just before bedtime, which is 7 to 8 hours after opening. Not much else happened once we got to the 72-hour mark other than the sides plumping out a bit.
Once fully inflated, it was still remarkably slim when compared to its Hybrid Mattress counterpart. This would be a great option if you have a bunk bed or kids bed frame that isn’t shallow.
Does it deliver?

“It’s like sinking into a cloud”[/caption]
Hybrid Kids Mattress, £349 from Simba
“It’s like sinking into a cloud,” was the review after the first sleep.
My parents also had to drag her out of bed that morning, and if that’s not a vote of confidence then I don’t know what is.
“It’s like sinking into a cloud,” was the review after the first sleep. My parents also had to drag her out of bed that morning, and if that’s not a vote of confidence then I don’t know what is.
I also tested it out for myself with a 20-minute power nap, as Simba claims that because of its standard single size, it can be used by adults too.
It felt a bit firmer than my Simba Hybrid mattress, and not as luxurious as my Simba APEX mattress. Still, it was a dream to sleep on.
My sister also said that it was quite firm. I don’t think this would be the case if she was a bit heavier, but as she is so slight, she doesn’t have a lot of ‘sinking power’.
With some regular use and growth, I think this issue will even out.
My sister takes after me and loves to snack, making the removable and washable cover is very helpful — it helps with Capri Sun spills and biscuit messes.
The cover fits in a standard-size drum, too, meaning no sad visits to the local deserted launderette.

What parents are saying about the Simba Hybrid Kids Mattress
With an average rating of 4.9/5 and 1803 reviews, people have got a lot to say about the Simba Hybrid Kids Mattress.
My parent’s primary concerns when choosing a mattress were muscle support and comfort.
Her (and my) mum said: “My daughter is hyper-mobile and has dance classes several times per week which is why we wanted to ensure that she really got the rest that she needed — we wanted a mattress that was supportive on her aching muscles”.
Another parent, writing on the Simba website, said: “As parents of a toddler, the inevitable sleepless nights have impacted everyone’s sleep. So we invested in Simba mattresses so that no matter which bed we sleep in, our comfort is never compromised“.
Another wrote: “My 9-year-old daughter got this mattress and absolutely loves it! When I asked her to describe how it felt she simply said “AMAZING.””

Simba Kids Mattress alternatives
Unsurprisingly there’s a wealth of options out there when it comes to kids’ mattresses.
One of Simba’s primary competitors, Nectar, came out with a kids’ mattress late last year, and while we’ve not yet tried it ourselves, initial reviews have been good. It’s also slightly cheaper than Simba’s, at £265.
A sub-£200 option is the Silentnight Healthy Growth range, which consistently gets good reviews from parents.
Jay-Be is also renowned for its kids’ mattresses and has a wide selection available at Bensons for Beds.
Simba Kids Mattress: The Verdict
The final say… should you splash your cash with Simba?
In our humble opinion, it’s a no-brainer. I am yet to have a bad experience with a Simba mattress and I’ve tried a few in my time, from the entry-level Hybrid right through to the top-of-the-range APEX.
A slimmer bed frame or using it on bunk beds is great because of its slimline nature.
One 11-year-old girl feels very happy and well-rested.
