Firmness Info
The Ultima is available in 3 different firmness options:
  • Soft feel (3/10 firmness) Recommended for side sleepers, and those with a smaller build or weight.
  • Medium feel (5/10 firmness) Recommended for back and side sleepers and those who change positions throughout the night.
  • Firm feel (7/10 firmness) Recommended for front sleepers, average to heavier body frames, and people with back problems.
The Simba Go Hybrid 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
Ultima by name, ultimate by nature. With 10 layers of supreme, innovative, temperature cooling support, the Ultima is luxury sleep incarnate. The 10 layers are:
  • Cooling Cover
  • Breathable Mattress Cover
  • Breathable Memory Foam
  • Refreshing Open-Cell Memory Foam Comfort Layer
  • 2000 Nano-Springs
  • Unique Support Layer
  • Dynamic Airflow
  • 4000 Pocket Springs
  • Support Foundation
  • Non-Slip Base.
The Simba Green Organic Go Hybrid is Simba's most sustainable and organic mattress, with half the carbon footprint of traditional Hybrids. The six layers of the Go Hybrid® are:
  • Breathable GOTS-Certified Organic Cotton Cover
  • Breathable, Recycled Simba Renew layer (up to 75% recycled)
  • GOLS-Certified Natural Latex
  • Up to 2,000 25mm conical pocket Aerocoil™ springs, enclosed in a 100% polypropylene pocket
  • 5 Zone Supportcore™ base with up to 900 pocketed steel barrel springs
  • Breathable 3D mesh base cover made with 50% recycled fibres.
Comfort Info
The Ultima has an innovative thermic cover that has been tested to reduce temperature by 2 degrees. Additionally, the continuous passive and dynamic airflow designs inside the mattress ensure optimal sleeping temperature.
Latex is a renewable, bountiful, and biodegradable material, as well as being naturally anti-microbial. With no chemical glue between mattress layers it makes disassemling and recycling even easier. What makes the pocket spring base so unique, is its sustainability factor: it is 100% recyclable because there is nothing in it apart from steel and recycled fibres. Plus it can be rolled and boxed, which makes this mattress it more efficient to transport thus reducing its carbon footprint.
Support Info
The Ultima offers an incredible 6,000 nano and pocket springs in twin layers for the highest quality support, cushioned with luxurious layers of premium memory foam. With unique 'wave technology', this ensures the right levels of support and pressure distribution, which helps to provide better spinal alignment while you sleep. The zones cater to various areas of your body supporting your head and neck to keep the head inline with your spine, a softer sink under the shoulders to relieve pressure and provide support, hip support, and zonal lower leg and foot support helping to keep your body aligned.
The Simba Go Hybrid is a creative blend of Simba's patented mattress tech with natural latex. This mattress is designed to support all the contours of the body: organic latex provides superbly responsive cushioning and comfort for all the pressure points of your body, while a layer of our patented Aerocoil® springs and our zoned pocket spring unit offer effective, consistent spinal support. Firmer rows of springs at the edges of the mattress gives edge-to-edge support.
Comfort Specs
Breathable Memory Foam
The exquisite first layer of memory foam features innovatively designed zonal perforation, inviting cool and refreshing airflow to the surface. Refreshing Open-Cell Memory Foam
The ultimate comfort layer - the innovatory, large open-cell structure memory foam allows for 4 times the airflow for optimal breathability and comfort. Dynamic Airflow
The dynamic airflow system actively and continuously draws fresh air into the core of your mattress, and engaging with the springs layers, pushes cool air up and throughout the mattress.
Simba Renew™ Layer
Is a soft, anti-allergenic and breathable layer, made from as much as 75% recycled yarns, with a few new fibres to ensure optimum durability. Located directly under the cotton cover it aids airflow and discourages dust mites. Organic Latex
This Global Organic Latex Standard (GOLS) certified latex has added perforations to encourage airflow, and graphite to absorb excess heat. Aerocoil® springs
These patented micro springs help prevent overheating with increased air circulation and ultra-responsive comfort - flexing gently in response to you and your partner's every movement, offering personalised support to one without disturbing the other. Supportcore™ springs
A spring base, rather than foam, encourages even more airflow through the mattress. Breathable 3D Mesh Base Cover
Is a combination of recycled and new fibres that allows maximum airflow through the mattress layers and aids shape retention. It is made with 50% recycled fibres.
Support Specs
Nano-Springs
A twin blanket of 2,000 nano-springs, ergonomically designed to evenly distribute your weight. Unique Support Layer
This layer provides support in your individual choice of comfort feel. Pocket Springs
A twin layer of 4,000 large pocket springs, this layer provides the perfect level of push-back and bounce. Support Foundation
A high-density support base offers the best foundation giving the mattress a durable structure that will last for years.
Latex Comfort Layer
Natural latex is a by-product of the rubber tree and has been around for centuries, it gives luxurious support and pressure distribution. Aerocoil Spring Layer
Being just 25mm, these tiny patented, strong, cone-like springs offer superior body support. Supportcore™ Base
With up to 900 pocketed springs, varying in diameter, to create 5 support zones for the parts of your body with more specific needs, such as your shoulders and hips.
Fabric Specs
Cooling cover
Brook + Wilde's most premium cool-to-touch cover. Thermic fabric containing microcapsules which proactively manage body temperature by storing and releasing any excess heat. Tested to offer 2°C more cooling. Breathable mattress cover
Indulgently designed for your comfort, this low friction woven fabric reduces the shear action between the cooling cover and the top layer of breathable foam. Non-slip base
The non-slip base ensures that your Ultima mattress stays in place on your bed frame.
Pure, cooling, organic cotton, certified to the Global Organic Textile Standard (GOTS) a body which monitors production from field to factory. This luxurious cover is composed of 95% cotton, 1% Spandex and 4% Polyester. All cotton is from 100% Global Organic Textile Standard certified sources - this certification regulates organic, natural textiles during their entire production, from the chemical-free growth and safe harvest of raw materials, through to responsible manufacturing such as the banning of dangerous dyes and fair employment practices such as a living wage. Note the cover is not removable or washable but you can add a mattress protector or spot clean. There are 4 handles to easily manoeuvre the mattress.
