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.
Who is the Simba Hybrid Luxe most suitable for?
The highly advanced design of the Simba Hybrid Luxe means that most people would likely find it comfortable.
However, we think it’s a particularly good choice for:
- Couples/restless sleepers
- Side and back sleepers
- Medium-weight sleepers
This is the most premium option of all Simba mattresses and a good choice for those looking for a higher-end product. 👑

The Simba Hybrid Luxe is great for light sleepers who have trouble staying still.
However, if you’re on a budget, then the Simba Hybrid or Simba Hybrid Pro are considerably cheaper.
The Simba Hybrid Luxe might also not be well suited to:
- Excessively hot sleepers
- Stomach sleepers
- Heavier weight sleepers
For heavier people or those that sleep on their stomach, the DreamCloud Luxury Hybrid may be a better choice.
This hybrid mattress has a firmer feel that supports every weight.
Simba Hybrid Luxe review of firmness
So, how firm is the Simba Hybrid Luxe? 🤔
Just like the Simba Hybrid Pro and Simba Hybrid, this one-size-fits-all mattress comes in a medium-firm feel.
This makes it ideal for most people who sleep on their side and back
However, though it's rated as a medium-firm mattress, what feels firmer to some may feel softer to others. 🧱🧸
Always consider individual factors when reading mattress reviews, such as your weight and sleeping position.
How deep do you sink into the Simba Hybrid Luxe?
The Simba Hybrid Luxe might have a slightly ‘plusher’ feel, which hugs better around the body than the previous Simba models.
This is mostly due to the extra layers of Simba-Pure foam, which allow for extra sinking. ⚓
The edge-support system was less effective when weight was contained in one single spot.
We found that the edge support system performed most well when weight was distributed evenly across the mattress.
As you can see from the images below, The Simba Hybrid and Simba Hybrid Pro appear to sink much less during our edge test. 👇
However, it’s important to point out that other factors may have contributed. 💭
For example, the tester is sitting slightly closer towards the middle of the other Simba mattresses, which will have offered better support.
What does sleeping on the Simba Hybrid Luxe feel like?
Overall, sleeping on the Simba Hybrid Luxe was very comfortable.
Laying down on the mattress felt supportive and you could tell the mattress was designed with high attention to detail. 🔍
We felt the mattress supported every sleeping position but is a particularly great choice for back and side sleepers.
In the side sleeping position, the mattress moulded around the body whilst keeping the spine neutrally aligned throughout the night.

For lighter-weight side sleepers, you may feel more comfortable on a mattress with slightly more give.
Likewise, heavier-weight sleepers may feel they sink too much into the mattress.
The medium-firm feel of this mattress makes it a perfect choice for back sleepers.

As you can see, the Simba Hybrid Luxe contours around the heavier parts of the body (hips, shoulders, and head) without bending the spine too much.
The contoured support zones, Simba-Pure foam and clever pocket spring system worked in unison.
We think the mattress also suited lighter-weight stomach sleepers. 🎈

The Simba Hybrid Luxe is suitable for lighter weight stomach sleepers.
Our tester was supported fairly well in this position and the spine is well aligned.
However, slightly heavier stomach sleepers may need a firmer mattress. 🧱
If you feel pain in your lower back whilst in this position, this indicates that you need a firmer mattress.
Another important note is that our tester tried this position without a pillow.
Sleeping without a pillow in this position helps to take pressure off the spine and reduce tension. 😨
Is the Simba Hybrid Luxe good for couples?
The composition of the Simba Hybrid Luxe makes it a great buy for restless sleepers and couples. 👩❤️💋👨
The combination of pocket springs and high-quality Simba-Pure foam makes the perfect recipe for a low motion transfer mattress.
Motion transfer is how much movement is isolated in the mattress.
For example, if you feel your partner getting out of bed during the night, your mattress likely has high motion isolation. ⛵
A low motion mattress stays still across the entire mattress, preventing that bouncy feeling.
This also helps to prevent restless sleepers from tossing and turning throughout the night.
Mattresses with pocket springs and/or memory foam typically offer great motion isolation.
Our favourite low motion isolation mattresses
Great temperature regulation
Memory foam mattresses have a bad reputation for causing overheating during the night.🥵
This is because heat is retained inside memory foam material, creating a warmer sleep.
However, the Simba Hybrid Luxe is made with Simba Pure foam - a similar but much cooler alternative to memory foam.
The pocket spring layers also allow air to flow throughout the mattress.
Simba has made temperature control a prime focus of the Simba Hybrid Luxe mattress.
Simba Hybrid Luxe cooling properties include:
- Top cover with open-cell casing for enhanced breathability.
- Bamboo wool layer with thermal control and moisture-wicking properties.
- Open-cell Simba-Pure foam layer which encourages airflow.
- Spring layers distributed between foam with optimal ventilation.
- Zoned support base with contoured grooves for better circulation.
Overall, we found the Simba Hybrid Luxe comparatively cooler compared to some other mattress brands and overheating wasn’t an issue.
But we found there was little difference in coolness between the Simba Hybrid Luxe and Simba Hybrid Pro despite some claims.
But if you naturally feel hot during sleep, then a mattress with foam might not be your best option.
A much cooler alternative would be a natural pocket-sprung or latex mattress.
Simba Hybrid Luxe review of composition
Who said a bed-in-a-box mattress had to be basic? 🤔
Simba Sleep has created their most advanced mattress yet in the Simba Hybrid Luxe.
This premium mattress is the "daddy bear" of the 3 Simba mattresses, made with 10 layers of high-quality materials.
No wonder this mattress is so deep - 31cm to be exact! 🤯
That's a whole 6 cm deeper than the Simba Hybrid!
However, our Simba Hybrid Luxe measured at just under 30 cm.
The eleven mattress layers of the Simba Hybrid Luxe are:
- Breathable top cover
- Natural bamboo wool layer
- Graphite infused Simbatex
- Two layers of 25mm Aerocoil springs
- CertiPUR stability layer
- Aerocoil spring support layer
- No roll-off SupportCore base
- Simba ReGen base layer
So, what do these layers actually do? 👇
Simba Hybrid Luxe mattress layers
1. Natural bamboo wool layer
The natural bamboo wool layer is one of the unique aspects of this premium-range mattress. 🐼
Bamboo is a fantastic organic material for sleep products, which is becoming increasingly popular in products.
As bamboo is hypoallergenic and naturally antibacterial, it's a great choice for those with allergies. 🤧
The top layer of bamboo wool wicks away moisture and dries fast.
This makes it a great option for those that sweat often during sleep.
The bamboo wool sleep surface is also thermal regulating. 🌡️
This means it will keep you toasty on those chilly nights and help to disperse heat during the summer months.
2. Graphite infused Simbatex
Open-cell graphite-infused foam with cooling technology. ❄️
This advanced foam is as soft and comfortable as memory foam but with better ventilation.
Simbatex has 30 times the airflow of memory foam for a noticeably cooler sleep.
The open-cell structure of the foam allows better circulation and the graphite infusion encourages cooling. 🌬️
This makes it much more breathable and adaptable than polyurethane foam found in regular memory foam mattresses.
The advanced memory foam moulds around the body to provide instant pressure relief. 🤗
Most polyurethane foam mattresses are made with TCPP (a toxic flame retardant) to meet fire safety regulations. 🔥
Exposure over time to TCPP can be harmful to your health.
Simba-Pure is free from TCPP, parabens, phosphates and other organic pollutants whilst still exceeding fire regulations.
4. Two layers of Aerocoil pocket springs (2.5cm/ 1 inch)
Many hybrid mattresses have a base layer of pocket springs with a comfort layer of memory foam. 💭
However, the Aerocoil springs in the Simba Hybrid Luxe serve an entirely different function.
Simba double-up the 25 mm Aerocoil springs to create a dynamic comfort spring system.
The spring layer gives the mattress a more flexible feel which adapts with the body alongside the Simba-Pure foam. 🥰
6. Carbon steel spring layer (4 cm/ 1.5 inches)
The second spring layer adds an additional layer of flexibility. 🤸
Placed strategically between two Simba-Pure foam layers, this layer not only provides comfort but an advanced circulation system.
The larger springs also deliver some pliable support that works with the body rather than against it.
The Simba Hybrid Luxe offers the most individual support with up to 4000 springs.
7. CertiPUR stability layer
The CertiPUR foam layer contributes to the stability of the mattress.
It acts as an intermediary between the Aerocoil spring layer and the SupportCore base while simultaneously promoting airflow.
8. SupportCore base layer
The Simba Hybrid Pro is now made with a spring foundation.
This base incorporates up to 1000 barrel springs, offering full body support up to the edges and eliminating any sagging.
These deep, barrel-shaped springs are constructed from tempered steel.
Using a spring base is not only more environmentally friendly but also makes the mattress more breathable.
9. ReGen base layer
This setup also includes a layer of Simba ReGen surplus foam.
All the foam incorporated aligns with the CertiPUR standard, ensuring it is devoid of any environmental pollutants and hazardous substances.
Simba Hybrid Luxe review of cover
Every Simba Hybrid Luxe mattress comes with a removable knitted mattress cover.
Made from 99% polyester and 1% elastane, the hypoallergenic cover prevents dust mites and bacteria.
However, we encourage you to still use your regular sheets and a mattress protector for extra protection. ☔

Side handles for easy movement
We were pleased to discover the Simba Hybrid Luxe comes with side handles.
As the mattress is fairly heavy and deep, the handles make moving it around much easier. 🤹

You should never flip the mattress, but we recommend rotating it every 6 months.
The mattress comes with 8 handles altogether (2 on each side) making it convenient to move around.
Can you wash the Simba Hybrid Luxe cover?
The Simba Hybrid Luxe cover can be removed and washed. 🧼
This is another benefit that makes the Simba Hybrid Luxe a better design than the previous Simba mattresses.
Check the washing instructions on the label of your Simba Hybrid Luxe mattress. 🏷️
The Simba Hybrid and Simba Hybrid Pro mattress covers can be removed, but cannot be washed. ✋
Having a washable cover will help to remove bacteria, moisture build-up, stains, and improve the overall lifespan of your mattress.
However, to ensure your mattress is fully protected, we highly recommend using a waterproof mattress protector.
This will protect the mattress from accidents, bacteria build-up, and increase the overall lifespan.
Simba Hybrid Luxe mattress sizes
The Simba Hybrid Luxe is available in most UK sizes.
The Simba Hybrid Luxe comes in the following sizes:
- Simba Hybrid Luxe single size: 90 x 190 cm (3’ x 6’3”)
- Simba Hybrid Luxe mattress small double size: 120 x 190 cm (4' x 6'3")
- Simba Hybrid Luxe double size: 135 x 190 cm (4.4” x 6’3”)
- Simba Hybrid Luxe king size: 150 x 200 cm (5’ x 6’6”)
- Simba Hybrid Luxe super king: 180 x 200 cm (6’ x 6’6”)
However, it is not currently available in small single, emperor or EU-size mattresses.
If you need one of these sizes, consider the Simba Hybrid or Simba Hybrid Pro.
Simba Hybrid Luxe depth
As previously mentioned, the Simba Hybrid Luxe mattress is extra-deep, measuring 31cm (although ours fell a few centimetres short of this.)
You might feel like the Princess and the Pea on this mattress, but it’s not always ideal to sleep on one so deep. 🤔
For the elderly and physically ailed, we would recommend a thinner mattress which will make getting in and out of bed much easier. 👵👨🦽
Alternatively, lower bed frames can be bought which will help to accommodate the extra height.
Another downfall of deep mattresses is that ultra-deep sheets will need to be purchased.
Aeyla Eucalyptus Silk Sheets can fit a mattress up to 36 cm deep. 🤯
These sheets also have natural cooling and moisture-wicking properties, making them the perfect choice for this mattress.
Simba Hybrid Luxe mattress prices
The Simba Hybrid Luxe is the most expensive mattress in the Simba Sleep range. 💰
However, it is also the most premium option.
To simplify things, we’ve broken down the prices for each mattress and what you get for your buck:
Price* | Composition | Purchase | |
Simba Hybrid | £600 - £1100 |
5 layers (25cm deep) including 3 Simba-Pure foam layers and up to 2,500 springs. 4 handles for ease of movement Removable hypoallergenic cover (non-washable) |
40% OFF SIMBA HYBRID |
Simba Hybrid Pro | £1000 - £1500 |
7 layers (28cm deep) including 3 Simba-Pure foam layers, natural wool layer and up to 5,000 pocket springs. 4 handles for ease of movement Removable hypoallergenic cover (non-washable) |
40% OFF SIMBA HYBRID PRO |

10 layers (31cm deep) including 4 Simba-Pure foam layers, natural bamboo wool layer and up to 6,000 pocket springs. 8 handles for ease of movement Removable and washable hypoallergenic cover |
40% OFF SIMBA HYBRID LUXE |
The Simba Hybrid Luxe is expensive, but it also has nearly double the pocket springs and layers of the Simba Hybrid.
Simba also offers interest-free credit, spreading the cost of the mattress across 6, 9, or 12 months.
But ultimately only you can decide if the Simba Hybrid Luxe mattress is worth the high price. 💭
If you're looking for a cheaper alternative that doesn't compromise on quality, consider the Simbatex Foam mattress instead.
This all-foam mattress is made up of four premium Simbatex foam layers.

Simba Hybrid Luxe review of delivery
The Simba Hybrid Luxe is a bed-in-a-box mattress. 📦
It’s been compressed and rolled up into a box, for quick and easy delivery.
Simba offers a white glove delivery service. 🚚
This means they will bring the new mattress to your room of choice.
Delivery is free to mainland UK addresses and can be at your door in as little as 3 days!
As the Simba Hybrid Luxe is compressed into a box, it can easily be transported.
However, it will be down to you to unpack it onto your bed base.
Follow the steps below to ensure you unwrap the mattress correctly. 👇
1. Open the box and find the carefully packed cutting tool
The cutting tool provided will mean you can cut into the plastic without causing damage to the mattress itself. ✂️

2. Remove and unroll the mattress
When you first take your new mattress out of the box, it will look like a burrito. 🌯
You’ll need the cutting tool to cut the first layer of packaging and unroll it still in its plastic.

3. Use the cutting tool to remove the plastic
Once your Simba Hybrid Luxe has been unrolled, it’s time to decompress. 🎈
Cut through the remaining plastic (be careful not to damage the mattress) and watch the mattress decompress.

4. Remove all plastic and obstructing objects
Fully remove all the plastic packaging and ensure there are no objects surrounding the mattress that might interfere with its decompression.
Most Simba mattresses reach their full size in 3-6 hours, but some can take as much as 72 hours. ⏳

It’s probably a good time to put the kettle on and start thinking about dinner…
5. 6 hours later...Sleep!
After the mattress has fully decompressed, it’s time to try it! 🙌

Some memory foam mattresses come with a faint chemical smell.
This is known as off-gassing. ♨️
However, as mentioned previously, Simba mattresses are made with CertiPUR certified and TCPP-free materials.
So, the smell should be barely noticeable.
If you do notice the smell, open a few windows and it should disappear after a few hours.
Simba Hybrid Luxe trial period
Every Simba Sleep mattress comes with a money-back 200-day trial. ⏳
This means you get a whopping 200 days to sleep on the mattress before deciding if you want to keep it.
In the unlikely event that you don’t get on with it, contact the Simba team and they will arrange a collection and full refund.
Most retailers only offer between 30 - 40 nights for a sleep trial, whilst online brands are typically up to 100 nights. ⏲️
Simba Hybrid Luxe guarantee
The Simba Hybrid Luxe also comes with a 10-year guarantee.
This includes any issues with the mattress that are caused by faulty workmanship. 🛠️
If you find a fault, contact the Simba team within 30 days of spotting the issue and be ready to provide proof of purchase.
However, you won’t be covered by accidental damage such as stains and soiling or damage caused by pets or children.
Even more reason why you should consider investing in a mattress protector for extra peace of mind. 😅
Should I buy the Simba Hybrid Luxe?
Is the Simba Hybrid Luxe really the best mattress in their collection? 🤔
The Simba Hybrid Luxe is a top-of-the-range mattress that exceeds its predecessors in both quality and price.
If you’re looking to splash the cash on a high-quality mattress for a premium sleep experience, then the Simba Hybrid Luxe is a no-brainer.
However, if you can’t quite stretch the budget, then consider the Simba Hybrid or Simba Hybrid Pro instead.
There are but a few subtle differences in the Simba Hybrid Pro at a fraction of the cost.
So, you can save the pennies and sleep like a log at the same time. 💰💤
