How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.

Other features, like general firmness, comfort, mattress cover, delivery conditions, and trial period, are all the same.
Nonetheless, let’s take a closer look at the Simba Essential mattress. 🕵️♀️
Simba Essential firmness
Having tried other low-height mattresses before, we were rather surprised at just how firm the Simba Essential is. 😳
We’d rate it at 7.5 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.
This firmer feel may seem a bit unusual but makes sense if you’re considering that low-height mattresses provide less playroom in terms of sinkage.
Standard mattresses can sink in a bit and still offer good support. 👍
Low-height mattress, in contrast, lose support very quickly with sinkage.
There is simply “less mattress” to play with.
Measuring sinkage depths
To make sure we weren’t too biased - the level of firmness you feel does depend on your weight and build, after all - we relied on some measurements for this Simba Essential review. 🧮
For this, we measured how deeply we sank into the foams in different sleeping positions.
This allows us to gauge how the mattress responds to body weight and how much support it gives.
When testing, we always take readings at the same place:
- Sleeping on the stomach: We measure at the stomach.
- Sleeping on the side: We measure at the shoulders and hips.
- Sleeping on the back: We measure at the shoulders and hips.
We’ve also included measurements of standing on the mattress, which give a good indication of maximum sinkage.
Here are our results:
|Test sleeper 1 (1.80 m / 72 kg)||Test sleeper 2 (1.63 m / 57 kg)|
|Lying on the back:||Shoulder: 1.5 cm (0.5 inches)
Hips: 2.5 cm (0.7 inches)
|Shoulder: No sinkage evident
Hips: 0.5 cm (0.1 inches)
|Lying on the side:||Shoulder: 3 cm (1.1 inches)
Hips: 4 cm (1.6 inches)
|Shoulder: 0.5 cm (0.1 inches)
Hips: 1 cm (1.1 inches)
|Lying on the stomach:||No sinkage evident||No sinkage evident|
|Standing in the middle:||12 cm (4.7 inches)||7.5 cm (2.9 inches)|
Even though both test sleepers immediately perceived the Simba Hybrid Essential 1500 Pocket mattress as firm, we were quite surprised to see just how firm it was when taking the measurements. 📏
These very low sinkage depths are indicative of a firm mattress, and make the Essential a tad firmer than the Hybrid.
But, sinkage is still optimal to support every sleeping position.
- The mattress gives fantastic support to stomach sleepers and back sleepers, ensuring optimal spinal alignment.
- It also gives good support to side sleepers, allowing both shoulders and hips to sink in a little bit to enjoy optimal spinal alignment.
That said, lower-weight individuals or those of a smaller build may find the mattress a bit too firm in the side position.
Because there’s not much sinkage, shoulders and hips may be pushed up a little too much, causing spinal misalignment.
This would need to be assessed on a case-by-case basis though.
Luckily, the Simba Essential comes with a risk-free trial period, so you can try out the mattress to see if you like it. 🥳
Average edge support
Even though the Essential is quite firm, it does lack in terms of edge support.
This is also the one notable difference between the Simba Essential and the Simba Hybrid - the Essential lacks the EdgeLift technology layer.
This layer is meant to provide edge-to-edge support in the original hybrid mattress.
Naturally, then, you can assume that the Simba Hybrid Essential 1500 Pocket mattress offers less edge support than the Simba Hybrid. 🤷♀️
It’s still not terrible, though.
If sitting or kneeling at the edge of the mattress, the lack of edge support is quite pronounced.
This is because a lot of weight is concentrated in one location.
But if you’re lying on the mattress, edge support is actually quite decent and the mattress remains incredibly comfy.
This may change slightly according to your weight and build, but you still shouldn’t ever feel as if you’re falling off the sides of the bed while sleeping.
That said, we’d have a few recommendations here:
- If you like sitting at the edge of your bed, perhaps to read, paint your nails, or put on your shoes, then you should get a mattress with better edge support.
- If you’re sharing your bed with a partner, we’d suggest opting for a king-size mattress, just to make sure you have enough space to move comfortably without falling off.
- If you’re of larger build or slightly heavier, you should also look into a mattress with better edge support.
If you’re using the bed by yourself, though, you’ll have an excellent night’s sleep on the Essential.
Does the Simba Hybrid Essential sleep hot?
The Simba Essential mattress is quite temperature-neutral. ❄️
There are a few elements that play a role in this:
- Simbatex is an open-cell foam that’s 30% more breathable than standard memory foam mattresses, allowing for more airflow.
- The top layer is infused with cooling graphite.
- The 1500 pocket springs increase overall breathability.
- The side mesh cover allows heat to escape.
For our Simba Essential review, we found that the mattress regulated temperature well throughout the night. 🙌
We tested in spring conditions, with some nights warmer and some nights cooler. 🧊
Overall, the mattress slept cooler than the pillow top mattress we’d switched over from.
Simba Hybrid Essential 1500 Pocket mattress sizes
While Simba Sleep tends to offer tons of mattress sizes, the selection of Simba Essential sizes is limited.
It’s available in these dimensions:
- Simba Essential single mattress: 90 x 190 cm (3’ x 6’3”)
- Simba Essential small double mattress: 120 x 190 cm (4’ x 6’3”)
- Simba Essential double mattress: 135 x 190 cm (4’6” x 6’3”)
- Simba Essential king mattress: 150 x 200 cm (5’ x 6’6”)
This makes the Essential suitable for children, young adults, and young couples. 👩❤️👨
But, we wouldn’t recommend it to the elderly or slightly larger couples.
These groups may prefer thicker and bigger mattresses overall, like the Simba Hybrid Luxe.
Simba Hybrid Essential depth
The Simba Hybrid Essential 1500 Pocket mattress comes at a standard height of 20 cm (7.8 inches).
This is 5 cm (1.9 inches) below the bed-in-a-box industry standard. 📦
Low-height mattresses are generally much cheaper, so they’re a great option for children or guest rooms.
But higher mattresses tend to be more comfortable, look nicer in bedrooms, and make getting in and out of bed much easier. 🌟

Simba Essential mattress UK delivery conditions
The Simba Essential mattress is delivered within 3 business days. 🗓
Delivery is free.
Despite having a zero-contact delivery policy, your mattress can be delivered directly to a room of your choice. 🚛
Our Simba Essential arrived just two days after ordering.
The two-man delivery team was very kind and carried the box directly to the requested bedroom. 😁
Manoeuvring the box onto the bed frame was no problem, especially considering that the Essential is quite lightweight.
Vacuum-packed and compressed
The Simba Essential is delivered rolled up and vacuum-packed in a cardboard box. 📦
And how do you get a full-size mattress from this?
It’s quite simple:
- Place the box onto your bed frame.
- Pull out the rolled-up mattress.
- Cut open the plastic cover.
- As soon as the plastic cover has been removed, the mattress will start to expand.
- Roll it out across the frame, and remove the remaining plastic.
- The mattress will inflate to its full size.
Inflation can take place in a matter of minutes, but it can also take a couple of hours for your mattress to be fully expanded. ⏰
In our experience, the mattress inflated fully in under an hour.
What do you do with your old mattress?
Simba offers an old mattress removal service for an additional fee. 🚚
Simply select this option upon checkout, and Simba will collect your old mattress when they deliver your new one.
Does the Simba Essential smell?
You may notice some off-gassing when you unpack your mattress.
This is an odd chemical smell associated with bed-in-a-box mattresses.
Off-gassing is not toxic or harmful, but it can be unpleasant. 🧪
You should always let your mattress breathe for a bit.
It’s also best to unpack your new mattress in a well-ventilated room. 🏡
We experienced very minimal off-gassing with the Simba Essential.
There was some smell, but you had to stick your nose right up to the mattress to smell it - and even that disappeared within a few days.
Should you buy the Simba Hybrid Essential 1500 Pocket mattress?
The Simba Essential is one of the best budget mattresses we’ve tried. 💪
But, even though this is Simba Sleep’s cheapest hybrid mattress, it can’t qualify as a real budget purchase.
It's more expensive than many other standard bed-in-a-box mattresses, and it’s only a tad bit cheaper than the Simba Hybrid.
Save a little extra and go for the Simba Hybrid instead.
It’s much better value for money.
Alternatively, if you don't mind an all-foam feel, you can opt for the Simbatex Foam mattress, which is much cheaper.
If you are set on the Essential, though, we’d recommend this mattress to:
- Those looking for an exceptional low-height mattress.
- Young adults.
- Guest bedrooms.
Bonus: With a 200-day trial period, the purchase is completely risk-free. 🥳
