5Ingenious things about the Simba Hybrid® 3-in-1 Duvet

We use our engineering expertise and the latest technology to bring you the best night’s sleep ever. And here’s how it all works in the Simba Hybrid® 3-in-1 Duvet

The perfect temperature, all year round

We’ve designed a set of two duvets that work in perfect harmony to keep you at the best temperature for sleep, every single night of the year.

All year:
use the Spring/Autumn duvet (grey binding, 7 Tog)

Warmer nights:
use the Summer duvet (blue binding, 3.5 Tog)

Extra chilly nights:
snap the two duvets together for a thermal value of 10.5 Tog.

The 3-in-1 duvet includes a Simba storage bag for whichever duvet is not in use.


The gentle genius of Simba Renew

This is our (very fluffy) alternative to feather and down; it’s made from recycled PET bottle fibres. The fibres are combed and folded into airy, downy clusters, forming a super-soft material that provides both warmth and breathability.

The Simba Renew fibres in our 3-in-1 Duvet are also blended with 20% Modal; Modal is derived from natural wood pulp and helps to wick moisture away from the body.


Stratos® - your duvet thermostat

All our duvets have one side of cooling Stratos® technology; this enables the fabric to actively react to your body temperature, dissipating excess heat to keep you cool and dry. For optimum temperature control, make sure this side is closest to your body as you sleep.

The magic
of Modal

A technologically advanced material with natural temperature regulating properties; it’s also plant-derived so it’s totally biodegradable and 100% sustainable. It’s made from beech wood pulp, sourced from sustainably managed forests in Europe and manufactured under environmentally responsible conditions.

The 3-in-1 Duvet filler features a blend of Modal with Simba Renew where it adds long-lasting softness and shape, even after repeated washing. We also combined ultra-smooth Modal fibres with cotton on one side of the cover, where it supports the body’s natural cooling process by carrying away moisture to keep you feeling cool and dry.


A sustainable

For Simba, protecting the planet is as important as restful sleep. We’re proud to be the first UK-born sleep brand to be awarded certified B Corp™ status.

Our official B Corp™ accreditation is an accolade that is only awarded to select businesses that promote social and environmental change through how we work and operate, something we consistently strive for.

Simba Renew is made entirely from recycled PET plastic bottles and Modal is a naturally renewable raw material being made from sustainably produced wood pulp; the Modal in our cotton blend cover is also produced by chlorine-free bleaching and an integrated pulp-to-fibre process incurring both low waste levels and emissions.

We’re part of the Better Cotton Initiative (BCI), a not-for-profit organisation which makes global cotton production better for the people who produce it and the environment it grows in. Better Cotton is not physically traceable to end products, but BCI farmers benefit from the demand for Better Cotton in equivalent volumes to those we source.
