Our mattress provides five luxurious layers designed to fit you and help you get the quality of sleep you've been dreaming of.

Shaped For You
The Visco memory foam moulds expertly to your body shape. It's like a mattress tailor made for you.
Our perfectly engineered support base has 7 different zones to ensure a perfect night's sleep for all.
*Spring count is calculated to be the equivalent number of springs in a Simba King Size.
We used data from ten million sleepers to create a mattress for all body types and sleep styles.
We combine the responsive comfort of memory foam with top-to-toe support from our patented conical pocket springs.
The Simba Hybrid® is the most-reviewed mattress-in-a-box in Europe, with over 35,000 five-star ratings.
Front, back and side sleepers
Face down, curled up or sprawled out? It turns out it doesn't matter. We designed our mattress using data from 10 million sleepers, so however you sleep we've got you covered.
Don't disturb your partner
The Simba Hybrid's flexible zoned base and unique patented springs respond individually to each sleeper, so your movement doesn't affect your partner. Household harmony restored.
I'm moving house. How do I move or store my mattress?
Yes, Once our Hybrid® Mattress is out of the box, it doesn't roll back in or fold up without specialist machinery - so, like you, it enjoys a good lie down! Because of the innovative layered structure, it's best not to store the mattress on its side for an extended time (in the van on move day is no problem).
Can I clean my mattress?
Yes, Using a mattress protector should keep your Simba mattresses in excellent condition, including the cosy, hypoallergenic cover. But if you do need to give the cover a clean, check which type of mattress you have:
For the Hybrid® with the original cover (which doesn't wrap over the sides): use a light cleaning product on a soft, damp cloth in small, circular motions to spot clean and refresh.
Do I turn my mattress over regularly?
Yes, No-one enjoys doing this, so you'll be relieved to hear that all our Simba mattresses for adults are non-flip since our unique layering system is designed to offer incredible one-way support. If you want to really do your best by your mattress, rotating it every so often can help - maybe once a month to begin with and then reducing it to every 3-6 months.
Will I be able to get the mattress back in the box or roll it back up again?
Yes, Now that would be a sight to see! Once out of the box, there's no way to get the mattress back inside. We don't recommend attempting to fold or roll it as this may damage the spring layer inside.
Can I use an electric blanket with my Simba?
Absolutely! Just remember that a cooler room can help you get better sleep, and as a general safety recommendation you shouldn't use these if little ones are busy snoozing on the mattresses.
Do I need to use a mattress protector?
You certainly don't need to, but to keep your Simba looking pristine we suggest using a thin mattress protector.
Can I use the mattress on a sofa bed?
We don't recommend using Simbas with a sofa bed as folding the mattress in that way may damage the spring layer inside.
Can I use an adjustable bed?
Yes, the mattress has been fully tested and works perfectly with all types of adjustable and electric beds - it'll perform in any position that you find most comfortable! We also have our very own Simba Adjustable Base that's fully equipt with a massage function and USB charger so please check it out!
How long can I keep the mattress in the box?
Your mattress can live in its box for up to 9 months, but we'd recommend releasing it sooner and enjoying a restful night's sleep as soon as you can!
What base should I put my Simba on?
Our mattresses are designed to work on any firm, flat surface - it’s suitable for the floor, a slatted bed frame, or a box spring. As a general rule of thumb, the more surface area the better so if you choose to use a slatted bed frame, please ensure the slats are no greater than 3” apart. If you’re using an older box spring with only a few support slats, it is recommended that you use a length of plywood to offer the support to the mattress. If you have questions, please contact us.
My mattress has arrived, how do I set it up?
Set up is easy, just remove the mattress from the box and unroll the flattened mattress on your bed base. Use the handy cutting tool that you'll find inside and cut along the plastic to break the vacuum seal. Remove all the packaging and watch your Simba rise and expand before your eyes!
I've unpacked it, how long till I use it?
The hardest part is waiting! Although it can take up to 24 hours to fully form, you only need to allow 3-6 hours after releasing the mattress from the vacuum seal for it to be good to go zzzzzz.
Is there a break-in period?
We do suggest that you give your Simba at least 30 nights to ‘bed in’ – any new mattress can feel a bit different at first.
Will my mattress have a smell when I first open it?
Like anything new your mattress may have a smell. Since the mattress contains foam, you may find it does have an odour and if you're not familiar with foam mattresses this might be a stronger smell than you're used to. But please be assured, this is perfectly normal and safe. The smell will fade away within days of using and airing.
Can I use the mattress on the floor?
If that's what you're into, of course you can! It's just a good idea to ensure that there are no signs of damp in the room and that it's well aired.
Which way up does the mattress go?
Simba Hybrid® is made up of layers that are strategically placed for ultimate comfort and support, so it's important that they're used the right way up. The white polyester sleep surface is what you want to be sleeping on and you should notice a Simba tag on the top edge.
What does the 10-year mattress guarantee cover?

What safety tests have you done on the Simba mattress?
Our manufacturer is a National Bed Federation Approved Member (2016) – having been successfully audited by EXOVA BM TRADA against the NBF’s strict code of practice which sets out criteria for ensuring processes and procedures are in place for supply chain scrutiny and compliance with regulatory requirements, including flammability, cleanliness of fillings and trade descriptions.
They were also recognised by the NBF with a highly commended award for the 2015/16 Bed Manufacturer of the Year and they have received the SEDEX/SMETA Best Practice Guidance accreditation. All foam in the manufacture of our mattresses are CFC free.
How firm are your mattresses?
We call each Simba ‘perfect’ – every part is engineered and married together to give people of different sizes and shapes the perfect night's sleep.They offer medium to firm support. But hey, let's not get too caught up with firmness as it isn't about how soft or hard your mattress is, but instead what support it offers you.
I usually get warm at night, will Simba be suitable for me?
It’s a perfect match! Anything that contains memory foam is known to be warmer than standard foam but we have some tricks up our sleeve - we’ve crafted the perfect mattress that is specifically designed to keep you nice and cool. Our top Simbatex layer contains natural cooling balms and combined with the breathable sleep surface and grooved support base, helps to ventilate and cool the mattress.
How deep are your mattresses, will my sheets fit?
The perfect depth! The Simba Hybrid® is 25cm (10 inches) in height - we've packed a lot of technology into our range but your normal sheets will fit this just fine.
Will I feel my partner move around at night?
The nature of the Hybrid design in our simba mattresses provides minimal to no movement transfer and actively adjusts for two people of different sizes, to give you both a perfect night's sleep.
What's the weight limit for the Mattress?
The maximum weight per sleeper is 114kg for our adult Hybrid® mattress.
How big is the box?
Your Simba Hybrid®, whatever the size, will be delivered in a 107cm x 50cm x 50cm dimension box. You should see our flattening, folding and rolling machine in action, although stand well clear!
Has the foam used in your mattresses been tested to ensure it is safe?
We take our quality control incredibly seriously. We consistently work with our producers to ensure we enforce the very best procedures throughout the manufacturing process. We can also guarantee that the foam we use in our products does not contain the recent defective ingredients supplied by BASF's Ludwigshafen factory that has affected the wider industry.
Can you make bespoke mattresses?
While do have a large range of sizes, we don't currently offer made-to-measure sizing,
Is Simba suitable for children?
There's no reason why our mattresses wouldn't be suitable for kids, but as a general rule we would recommend a minimum age of 2 years as at this age children start to have better control of their bodies during sleep.
Does your mattresses meet all the fire safety requirements?
Absolutely! We comply with UK fire regulations BS7177 Low hazard for domestic use - the strongest in the industry.
Are you environmentally friendly and is the mattress vegan?
We make an effort to ensure that the manufacturing process for Simba is as environmentally friendly as possible. All waste foam from the manufacturing process is sold on for use in other products, such as flooring underlay, PE mats and other cushion products. The mattress is also rolled and delivered in a box to reduce the carbon footprint effect during delivery.
And yes, our Simba mattresss contain no animal products and are not tested on animals.
What is the Simba Hybrid® mattress made of?
We’ve combined comfort with the latest science and technology over 5 different layers, all with one thing in mind – the perfect night’s sleep.
From the top down we have developed a ‘breathe in breathe out’ hypoallergenic sleep surface that provides freshness and temperature control. The key to keeping the Simba Hybrid® nice and cool however, is our very own patented Simbatex - this is incredibly breathable and helps to promote airflow that cools the mattress naturally. Next, we have a layer of next-generation patented conical pocket springs that pivot in their pockets to adjust to your shape and movements. These minimise movement transfer between two people of different sizes and lie above and the layer of Visco memory foam to offer you incredible amounts of comfort without having to compromise on essential support your body needs over time. Lastly, all this goodness is resting on a 7-zone castellated support base that promotes durability, additional temperature control and ultimate comfort.
The Bunk mattress is a hybrid too and is made up of several layers including pocket springs and memory foam. It also has a special 'bedtime stories' layer - a felt layer that is designed to comfortably support the weight of a seated grown-up without sinking too much.
I have an allergy to latex, can I still use Simba mattresses?
Yes, you safely can. There's no latex in our mattress, so anyone can have access to a perfect night's sleep.
What is Simbatex?
Simbatex will keep you cooler than memory foam as it contains natural cooling soybean balms. It also has a much more open cell structure than standard foam and feels cool to the touch. We have included a layer of memory foam underneath it, to ensure your comfort and support are in no way compromised.
One of the major issues customers have with competitors in this market is the use of memory foam in the top layer. This feels good but is incredibly hot to sleep on, hence our work and decision to make Simbatex our top layer. It has all the benefits of memory foam but without the heat retention.
I'm pregnant, will a Simba be suitable?
You'll be relieved to hear that Simba Mattresses are designed to offer the same cosy, restful support for pregnant women as for all other adults. We take care with the details, like hypoallergenic covers and CertiPUR label foams.
I have a sore back - would a Simba help?
Even though we are not medical professionals we’ve received an overwhelming amount of positive feedback from those that suffer from back and various other aches and pains - they feel that their Simba mattress has helped them to finally achieve a great night’s sleep. We’ve used science to develop a mattress concept that is suitable for everyone. Our conical pocket springs pivot in their pockets and actively adapt to your individual body shape whilst you sleep, to offer maximum full body support and minimal motion transfer between sleepers. Each spring adjusts individually, adapting dynamically to you while you sleep, to offer you optimal support and a relief of pressure points. This means more comfort and less pain in your back. The addition of a memory foam also ensures that your comfort is not compromised in any way.
Why was Simba created?
We identified 3 issues:
There was too much choice in the mattress industry.
There was significant discounting and pricing artificially higher than should be.
There appeared to be no support or back-up for spurious claims made by many of our competitors.
We firmly believe in a fair price for a fair mattress.
We had done what we set out to do.We had created a mattress engineered for sleep.
