Simba Mattress Review
Disclaimer: This is my personal honest review of my Simba Mattress. I bought this mattress direct from the Simba website and it was not supplied to me free or discounted, I paid the full price. Please note that the links back to the Simba website are affiliate links. This means I get a commission if you buy via my link (you pay no extra). This is no way affects my objectivity. Just making this clear!
The Simba mattress is sold by simbasleep. They very unusually do not disclose details of the actual website registrant via the public whois database. The company was co-founded by James Cox and Andrew McClements in 2015, and started selling in 2016. They are based in London. It is Andrew McClements family who have been in the mattress industry since 1979 and this is why the website talks about their many years of past mattress history. The mattress is manufactured in Derby, UK. Simba is named after the pet name for James Cox partner.

At the time of this article only one version of the Simba mattress is being sold.
Simba truly is something different, compared to the majority of online companies who use all poly foam layers, Simba brings more to the table. Number one is the use of tiny micro pocket springs. Be under no illusion though when you read 2500 conical pocket springs, these are small micro springs and 2500 is the number in a King size mattress. Conical refers to their cone like or tapered shape which gives them a consistent spring throughout the range of movement.
Now having slept for some time on a Simba mattress I can say it does lend the mattress a somewhat spring like feel, but how much of that is down to these thin springs is hard to say. Given their size its best to think of the spring layer as a mesh type layer of small individually moving springs. The mattress has a 100% polyester cover, a synthetic latex top comfort layer, next layer is the micro springs, next is the memory foam layer and then the solid base layer.
The norm with many online mattress companies is little to no information as to the technical aspects of each layer in terms of density and ILD (as is the case with Casper). Kudos to Simba for openingly stating the technical specs on the website and which I quote below.
Cover:This is 100% polyester, thin and stretchy. Simba say this has been made in such a way as to make it breathable. Not sure what they mean by that (it is a phrase used by most mattress companies) but its thin and stretchy nature will make it cooling friendly. Breathable is normally a term used to mean the material is highly wicking. That is to say it lets air in and sweat out via evaporation. It will allow air to circulate to the layer beneath. The colour is ubiquitous white or off white top cover with grey or black sides. Personally I really do not like the colour combination but really it means nothing, the bed will be covered. Branding is via the label attached to the side saying Simba in blue letters. The sides of the cover have a nice textured feel, this is a quite unusual feature that I have not seen before and is pleasing on the eye. The Simba mattress does not have any handles. The top section of the cover can be unzipped and machine washed at 40 degrees. The grey base fabric can be cleaned with a soft, damp and clean cloth using small circular motions. The cover is an all in one piece that unzips from below making removal awkward. The cover is a one piece cover which unzips from the bottom making removal awkward.

Simba Mattress OverviewI found the online chat facility quite helpful. Companies are often reluctant to reveal too much technical detail and fall back to marketing speech such as “it will feel like sleeping on a cloud” when pushed. Simba chat team were open and helpful and worked hard to find information they did not have on hand. Their technical knowledge wasn’t that great (verging on poor) but they did try to get the information and get back to me. I was reasonably happy with the online chat but I have learned not to rely on information gleamed from chat from these mattress websites and to double check everything. The Simba Mattress offers above average materials, innovation and good design attributes. Its use of Latex for the top layer is great to see but you should note this is synthetic latex which is less preferable than natural latex. While this is 100% synthetic latex it still offers benefits over high elasticity polyurethane foam. This includes better longevity, better for cooling and better for allergies. The micro conical pocket springs is the unique selling point here and makes the mattress standout from the normal poly foam only offerings. Use of springs with foam makes this a hybrid mattress but it not the only online company offering this. The springs are 2 cm high pocket springs so they move individually. How much difference do such small springs make? Its hard to say, you can’t actually feel the springs even laying on the mattress or indeed pinching the layers together. But the mattress itself does have a spring like feel in a subtle way, it is by no means bouncy. The third layer is the memory foam layer memory foam and the bottom layer is the standard base. However Simba have added zoning in the bottom layer to improve spinal alignment and give at the shoulder area which is really important for side sleepers. The polyfoam layers are said to be CertiPur certified which means they are certified to be low in volatile organic compounds which is also known as off gassing and gives a mattress that chemical smell. The latex layer however is not certified and being synthetic will have a smell for a a few days before it dissipates.
Tests and Analysis:
Edge support is a little behind other foam mattresses I have tried. There is some considerable dip but enough to allow you to sit on the edge and say put your shoes on.
This tells us the main feel of the mattress and perhaps the single most important factor for determining your personal preference in feel. Simba Hybrid original mattress is definitely one of the softer feeling mattresses for one described as suitable for all sleepers (of the ones I have tried). It is in line with the Nectar memory foam mattress however and a little firmer than the Casper Original mattress. Noticeably firmer than the Una in its soft configuration. You may have expected Simba to be firmer given its headline of pocket sprung mattress and use of Simbatext said to be latex. However remember this is synthetic latex with different properties to natural latex and the springs are 2 cm micro springs, not full size pocket springs. Just behind the Vesgantti Luxe Hybrid mattress, the Leesa Original mattress and the Ergoflex 5g memory foam mattress in terms of firmness levels. Much softer than the Leesa Luxury Hybrid, the Otty Hybrid mattress and the Emma original mattress.
Simbatex being synthetic latex has less heat retention than poly foam. The top cover is also thin to allow for air flow. Some latex have holes in the layer as part of the manufacturing process which further aids cooling but Simbatex does not have this, again as it is synthetic. Simba is a good option compared to polyurethane foam or memory foam if heat retention is an issue for you.
Spot Relief (point elasticity):
This is the amount of foam outside the area of contact that is affected by the area being depressed. Less area of affect is better for actual body contouring. Very high density memory foam for instance is used in orthopedic mattresses because there is little area of affect outside the points of contact. Simba is good as you would expect for a foam mattress but behind most of the other mattresses I have tested apart from Leesa and Emma Hybrid. This is an effect of being on the soft side which by its nature means more foam is giving for the same amount of pressure. So by no means bad but not the best option if this is a primary concern.
Mattress for Sex/Bounce:
Of course this is highly subjective and will vary according to your requirements. In general a good mattress for sex will have good bounce while still having some conforming properties. You don’t want a trampoline (assumed) nor do you want a concrete floor. Simba does not have a lot of bounce, neither for the top layer or the mattress as a whole. It has some bounce but not a lot in comparison to others and is on a par with Leesa and Emma Original and ahead of HÜGGE but behind all the other mattresses I have tested so far.
18 stone (114 kg). This is just a guide. This about the weight they think the mattress loses its supportive properties.
The flip side of the bounce score is that low bounce lends itself to low motion transference. I also test this in combination with a vibration recording dropping a weight at one end of the mattress and recording how vibration make sit to the other end. The Simba mattress is excellent for low motion transfer, though still a little behind the likes of Ergoflex 5G mattress, Emma original Mattress and the Nectar Mattress.
Type of Sleepers this mattress suits:
The Simba is a good option for anyone with shoulder issues due to its softer than average feel and molding properties. However this also makes it not a great option for stomach sleepers where too much sag in the middle can lead to lower back ache and stiffness. Again a good choice for medium to light back sleepers who like a softer but still supportive feel.
This is tough to compare because most companies have permanent money off offers. I have to go by the advertised list price with no discount. Here Simba is a little pricier than some alternatives but then it is also a more premium mattress. As price is so closely tied to the quality of materials it is a little unfair to score on price because some companies are more open about what they use than others. For this reason I simply give the average price from its mattress offerings and where it ranks compared to the other mattresses I have reviewed.
Materials and Design:
Use of latex is a big plus albeit of lowest density for this type of mattress and fully synthetic. However this is a nice setup from polyfoam as often used on the top layer. The use of pocket springs again albeit micro springs is a plus. The memory foam and base layers are a standard 50 kg/m3 (3 pcf) and 33 kg/m3 (2 pcf) respectively. However the polyurethane layers (3rd and 4th) are CertiPur certified. Above average for materials.
There is a strong chemical smell from the top synthetic latex layer when you first expand the mattress. This is normal for synthetic latex. Although strong it does disipate in a few days.
I can only tell you how I found the mattress as a 65% back 35% side sleeper and at 13 stone (82 kg, 182 lbs). I found it comfortable, supportive and on the softer side. If you are lighter than me it will feel firmer, if you are heavier it will feel softer. You can also change the feel with a firmer base, I use sprung slates which gives some added bounce. I can recommend this mattress if this is the feel you are after.
There are 7 zones which Simba call seventh heaven. They have cut groves through the base layer in four sections of the mattress which will match with your hips and shoulders and provides a little more give at these sections. Not all mattresses come with zoning which helps to tailor the mattress a little more to the human body. This is a good thing!
