Unique Points

The Simba GO hybrid mattress is very eco-friendly and is made up of 6 layers. Six layers? Yes. And every single one has a part to play in helping you sleep better:

  • Breathable, GOTS organic cotton cover
  • Breathable, recycled simba renew layer
  • GOLS organic latex comfort layer
  • Supportive aerocoil spring layer
  • Zoned supportcore™ base
  • Breathable 3d mesh

Four layer, customisable hybrid construction:

  • 4cm foam
  • 5 customisable comfort zones with 4 different densities of deep foam
  • 10cm individual pocket springs (coil count: 1,000)
  • The springs are encapsulated in a high density, supportive foam that makes up the base and the mattress walls. They're then covered in a medium density reflex foam that ensures you feel the bounce of the springs below.

Note: This brand has changed hands so many times, it's hard know the current quality of the mattress.

Comfort
A sumptuous layer of anti-allergenic Simba Renew fibres (up to 75% recycled) under the cotton cover aids airflow and discourages dust mites. A perforated natural latex layer offers increased breathability, as well as superbly luxurious support and pressure distribution.
The Tweak mattress (formerly known as the Nrem mattress) is designed to help all sufferers of chronic pain, including back pain. You can design your very own sleep experience by adjusting the foam tablets inside the mattress to give bespoke comfort and support to suit your specific pain needs. Pressure relieving, cooling comfort layer. This 4cm deep comfort layer contours and cushions the body for a greater level of comfort. The open cell structure wicks away moisture and keeps you cooler for longer.
Support
Up to 2000 of our patented, cone-like springs offer superior body support and increased airflow through your mattress. With up to 900 pocketed springs, engineered to offer 5 zones of targeted support for areas such as hips and shoulders.
5 customisable comfort zones with 4 different densities of deep foam. We use highly resilient Polyurethane foam in super soft, soft, medium and firm densities so you can get comfort and support in all the right places. This foam bounces back quicker than standard memory foam so you can turn over without feeling stuck. Our 5 comfort zones can be changed at any time so you can get your best night's sleep. 1,000 individual pocket springs for superior support and bounce. 1,000 full size pocket springs make up the mattress core. They're individually wrapped and move independently as you sleep, so you won't be disturbed by your partner's tossing and turning during the night. Our springs measure 10cm high and have a gauge of 1.5mm. As the springs are encapsulated in highly resilient base foam you get edge-to-edge support.
