The Company – Otty Sleep Ltd
The company behind the Otty mattress is called Otty Sleep Ltd who were formed in July 2016 and are based in Leeds in the UK. The sole founder was Michal Szlas. His story as told on the Otty website is very similar to that told on other online websites. The founders not being able to find the right mattress at the right price and so deciding to start a company and design and sell their own.

The Otty Pure Hybrid Bamboo Mattress – OverviewOtty offers the benefits of both full size pocket springs which move individually unlike open coil and memory foam for good molding properties. The foams used are all CertiPur certfied. The original Otty hybrid used 14cm pocket springs while the latest gen Otty mattresses use 16cm pocket springs. The extra 2cm can offer a slightly softer feel if all else was equal but it also means less comfort layers above if as is the case with the original the overall height remains the same. With the Otty Pure we do get an extra comfort layer as the cover itself contains 2cm of memory foam. This is extra comfort layer that you do not get on the original. Otty has always been geared to maximising airflow and cooling to alleviate some of the heat retaining properties of memory foam. They have pincore holes in the top of the memory foam layer (something normally only seen with natural latex) and holes around the sides and through the boxing edges for the pocket springs which aids airflow. Now with added bamboo and charcoal embedded into the memory foam Otty goes further in improving heat regulation. Otty has always been price focussed and continues to be one of the cheaper online options when compared like for like. It should be noted Otty Pure is manufactured in China.
Otty Pure Bamboo and Charcoal Mattress Layers:
It should be noted that all the polyurethane foams contained within the Otty mattress are CertiPUR and Europur certified. CertiPur lays down strict criteria on what can be used within the foam and the levels of those chemicals. This helps minimise VOCs (volatile organic compounds).
Otty Pure Cover:
As is so often the case the cover is a white top with dark grey sides but adds some colour with two blue stripes around the top edge. The edges have a light grey section running all the way round which is meshed and will allow for some increased airflow. Unfortunately there are no handles and the cover is removed by a zip which is right under the bottom of the mattress. However it is not machine washable and must be spot cleaned or wiped with a damp cloth. The cover is decent quality at 500gsm.
One big deal about this cover over the Otty Original is that it contains its own layer of memory foam, 2 cm of memory foam making it essentially the top comfort layer. This helps make it feel softer than the original. The other big deal is that it is made with Bamboo fibre. When bamboo is part of a fabric it means the bamboo has been dissolved and made into a useable fibre which has then been woven into the fabric. Bamboo fibre is both soft and flexible while also being naturally strong. Bamboo is also said to be hypoallergenic and antimicrobial. However there is some controversy over it’s antimicrobial properties which is partly related to how much bamboo kun remains after the process of making into a usable fibre. Another reason for its use in in bedding is that Bamboo fibre has been shown to reduce heat retention and thus provide a cooler sleeping surface. Bamboo is actually temperature regulating helping to keep you cool on warmer nights and warmer on cool nights. Bamboo fibre is highly wicking and breathable material, absorbing your moisture and then allowing it to evaporate. Essentially a semi-man made fiber often also called rayon from bamboo.
Memory foam is a slow responding material made from polyurethane foam but with additives that give it a unique feel. Unlike normal polyurethane foam or latex foam memory foam has little to no push-back. Unlike polyfoam that compresses under you memory foam dissipates around you which give it its great molding and body hugging properties. As memory foam works by absorbing your body heat some people find memory foam sleeps too hot.
The otty memory foam comfort layer has two features to help reduce heat issues. The use of bamboo and charcoal in the memory foam helps with temperature regulation. Charcoal is a lightweight black carbon residue produced by strong heat and most often derived from wood but not always. Indeed most often Bamboo is the original source for the charcoal when a memory foam is infused with bamboo charcoal. However Otty insist this is not the case with the Otty Pure Hybrid and that the bamboo and charcoal infused within the memory foam are seperate constituents. The properties of bamboo have been laid out in the above section on the cover. Charcoal has the benefits of being able to absorb some of the chemicals and VOCs from the foam along with any odours. It’s is also said to help with heat regulation. The memory foam also features holes across its surface known as pincore holes. This will aid with airflow from through the mattress and help again with any heat issues from the memory foam itself.
Effectively the third comfort layer. This polyfoam layer will help add some responsiveness to the memory foam layer above being more springy than memory foam. This layer also provides additional comfort before your hit the body supporting pocket springs below.
Up to 2000 pocket springs which means in a king size. Other sizes will have proportionally more or proportionally less.
The original Otty hybrid had 14 cm pocket springs while the latest generation has 16cm pocket springs. Potentially this could mean more contouring deep down. Also if all parameters are kept the same as in gauge, spring rate etc then taller pocket springs will feel a little softer. Pocket springs have an advantage over foam in they have a lot of side to side movement as well up and down movement. This however means they often not great on the edges because they can have a roll off effect. For this reason unless the pocket springs are actually designed to be used along the edges foam is used to add edge support. This is known as boxing in or encapsulated pocket springs. Otty has 15 cm of boxing in around the ends and sides of the mattress. The foam around the edges has holes through it to provide increased air circulation.
Pocket springs differ from open coil in that they are all individual pocket springs and not one long coil as in older open coil mattresses.
A base layer of foam to provide a stable base for the pocket springs above.
Otty Hybrid Mattress Overall:
Total height 28 cm (11 inches)
Average density: 44 kg/m3
Otty Hybrid Mattress weights:Based on weighing my own Otty Pure mattress (with cover) the weights would be:
|UK single||19 kg|
|UK double||28.5 kg|
|UK king||33.5 kg|
|UK super king||40 kg|
Tests and Analysis:
The pocket springs have foam around the sides to increase the edge support. The foam helps with edge support but could have been a bit firmer I think.
Firmness (how far it sinks for a given weight):
Certainly softer than the Original Otty I tried back in 2018. Now I would say slightly firmer than medium firm.
Otty have really focused on minimising any potential heat issues from having a top memory foam layer. My score for this section at 7.5 for cooling is actually a good score for memory foam and is about as good as it gets for keeping heat at bay. Remember memory foam works by absorbing your body heat so it will always have some potential for heat build up if you are sensitive to that.
Spot Relief (point elasticity):
I rate this by scoring the amount of foam effected outside the point of pressure and adjusting it by the firmness of the mattress. This is because of the high correlation between firmness and point elasticity. Without doing this a concrete floor would be rated as good for point elasticity when clearly it is not great for sleeping on! Otty Pure is quite good for point molding without excelling.
Otty Pure Hybrid is a bouncy mattress for sure, not quite the bounciest I have ever tried but certainly up there with them.
Bouncy Options: Tweak Mattress, Otty Original Hybrid
This is how much motion or energy travels across the mattress when a partner moves or something is dropped onto the mattress. Almost always this is the flip side of bounce, you can have a lot of bounce or you can have a mattress that absorbs motion transfer but you cant have both. Despite being a bouncy mattress the Otty Pure does well for motion transfer thanks to the memory foam layers on top.
Good for motion transfer: Ergoflex, Hugge
Mattress for Sex:
I rate a good mattress for sex by its combination of bounce and firmness level. Otty does well thanks to being bouncy but not over firm.
Other options for a good mattress for sex: Tweak Mattress, Vesgantti Luxe
Otty suggests a weight limit of 22 stone (139 kg) per person.
Type of sleepers this mattress suits:
Just edging past medium firm makes this a good option for both back and tummy sleeping. I found the shoulder firmness slightly firmer than the hip are so I have to mark the Otty Pure down slightly for side sleepers. Remember this is very dependent on your own weight and firmness level preference. Mys cores are just a general guide for the average person.
Still price focused though a little more premium than the Otty Original Hybrid.

You cant knock what Otty brings to the table. 16 cm pocket springs, CertiPur certification, Bamboo cover, Bamboo Charcoal memory foam, holes in the memory foam and around the sides for extra cooling.
All mattresses soften up. The rate at which they soften up is the differentiating factor. Otty Pure had no measurable softening in the 3 weeks I slept on it. A great result.
Alternative good mattress for softening: Ergoflex 5G
No problems from lingering smells with my Otty Pure Hybrid mattress. Only a hint of a smell with the cover off and sniffing up close. No smells in my bedroom of note.
Low smell mattress: Hugge, Una
Totally subjective and one persons comfortable is another persons nightmare. I found the Otty Pure very supportive as you would hope with those 16 cm pocket springs. Slightly firmer than I would prefer I certainly had no heat issues despite sleeping on Otty during some hot summer nights. Not quite enough give on the shoulder area near the side for me where the mattress actually uses foam for the boxing in.
