Firmness Info
On a firmness scale out of 10 (1 being soft and 10 being firm), the Pure+ Hybrid mattress scores a 5.5, which makes it the softest mattress in OTTY’s range. This is due to the extra layers of memory foam.
The Simba Hybrid Essential is a medium-firm mattress, however, 95% of Simba sleepers love their mattress. If it doesn't work for you, Simba mattresses that are returned are either refurbished or recycled; they never go near a landfill site.

Mattress Construction

Materials Overview
The OTTY Pure+ Hybrid Bamboo and Charcoal Premium mattress was designed with the ultimate support in mind. The layers of the Pure+ are:
  • 2cm Infused Embroidered Cover
  • 3cm Temperature-Regulating Memory Foam (Infused with Bamboo and Charcoal)
  • 8cm Pocket Springs (Up to 4000 Encapsulated Pocket Springs )
  • AirFlow System + Side Support

  • 2cm High Density Support Foam
  • 4cm Pocket Springs (Up to 4000 Encapsulated Pocket Springs)
  • AirFlow System + Side Support
  • 5cm High Density Base Foam.
The Simba Hybrid Essential is 20cm deep and contains all the Simba patented sleep tech that made Simba the world's most five star reviewed mattress brand. The four layers of the Hybrid® Essential are:
  • Breathable sleep surface (500g Hypoallergenic knitted cover)
  • Open cell graphite infused Simbatex foam
  • Up to 1,500 25mm conical pocket Aerocoil™ springs, enclosed in a 100% polypropylene pocket
  • Multi zoned foam support base.
Comfort Info
Bamboo and charcoal are sustainable materials with a myriad of health benefits. Natural Bamboo
Bamboo is a sustainable resource with amazing health benefits and has a variety of benefits when used in mattresses, notably, it is fully breathable, moisture-wicking, and temperature regulating. Activated Charcoal
Charcoal is another sustainable resource that provides additional benefits when used in mattresses, notably, for its odour-eliminating and hypoallergenic properties.
Each individual Aerocoil® spring flexes gently in response to you and your partner's movements, offering personalised support to each of you without disturbing the other. And as they compress and extend with you, they gently push air through the comfort layer, helping to keep you at just the right temperature.
Support Info
The Pure+ is a premium hybrid model with 2 layers of encapsulated pocket springs and five layers of foam. Each sleeper is supported separately thanks to two layers of individually encased springs, preventing any sleep disturbance caused by your partner's movements.
Using body profile data from ten million sleepers, Simba's sleep scientists have created a mattress designed and crafted for every sleeping style and body type.
Comfort Specs
Infused Embroidered Cover
Bamboo and charcoal infused memory foam increases the comfort of this mattress. Temperature-Regulating Infused Memory Foam
While providing added comfort, perforations in the foam allow heat to escape, keeping you at the ideal temperature throughout the night. The memory foam is also infused with bamboo and charcoal that have antibacterial properties. 2x AirFlow Systems
Unique airflow technology that works alongside the other layers to allow heat to escape and regulate temperature.
Open Cell Graphite Infused Simbatex Foam
This layer uses an open cell foam, that allows thirty times the airflow of memory foam. On top of that, Simba have infused it with a naturally occurring mineral called graphite; that draws heat away from your body.
Support Specs
8cm Encapsulated Pocket Springs
A top layer of springs that provides support to your body. 2x High Density Support Foam
Two layers of this specially designed Reflex Foam are placed inbetween the spring layers to provide comfort as well as additional support. 4cm Encapsulated Pocket Springs
A bottom layer of springs that offers additional support to your body from the core. Side Support
Both sets of springs are bordered by a foam perimeter creating an edge-to-edge sleeping surface. High Density Base Foam
This layer is at the bottom of the mattress and provides a solid foundation and ensures the mattress stands the test of time.
The Simba Aerocoil® microspring comfort layer
Up to 1,500 conical springs work together to distribute weight whenever they feel pressure. They are smaller and slimmer than the regular tall chunky bed springs, and because they are made of super-strong Titanium alloy (manufactured here in Leeds), this magic metal means even a micro size (25mm high with a thickness gauge of 0.9mm, which is the size of a very thin paperclip) gives you the support you need, but being so small and fine you won't feel a single one. Multi-Zoned Foam Base
With five separate support zones to make sure the base adjusts as you move, keeping your body in perfect, sleep-inducing alignment.
Fabric Specs
Infused Embroidered Cover
The top cover layer is quilted to 2cm of charcoal and bamboo infused memory foam to eliminate odour and wick away moisture. The cover is made from 97% Polyester and 3% Spandex. The Pure and Pure+ mattresses both have this additional 2cm of memory foam woven into the cover.
A 500g super soft, hand-knitted cover; this hypoallergenic sleep surface keeps your mattress fresh and cool. The cover is not removable or washable but you can spot clean it if you choose not to use a Simba Mattress Protector.
