Simba Hybrid 3-in-1 Duvet – Adaptive Year-Round Comfort in 4 Sizes

🌙 Simba Hybrid 3-in-1 Duvet – The Smart Way to Sleep All Year Round

Forget switching duvets with the seasons. The Simba Hybrid 3-in-1 Duvet gives you customised comfort 365 days a year with a clever layered design that adapts to your body and the weather. Engineered with Simba Renew Bio™ fill and Stratos® technology, this is your perfect sleep companion—no matter the temperature.

🧩 3-in-1 Layered Versatility

This innovative duvet includes two separate layers:

• A lightweight summer layer for warm nights

• A medium layer for cooler months

• Snap them together for a cozy winter option

Use them independently or combine both with easy snap fasteners to create the ideal TOG (thermal overall grade) level for each season:

• 🌞 Summer – 3.5 TOG

• 🍂 Spring/Autumn – 7 TOG

• ❄️ Winter – 10.5 TOG (combined)

This modular setup means you no longer need to buy and store multiple duvets for different seasons. One set. Three solutions.

🌬️ Climate-Controlling Stratos® Technology

What makes the Simba Hybrid duvet truly special is its Stratos® active temperature regulation layer. This NASA-inspired material:

• Absorbs excess body heat when you’re too warm

• Releases stored heat when you’re too cool

The result? A more stable sleeping temperature all night, helping reduce night sweats, cold spots, and sleep disruptions caused by overheating.

Whether it’s a heatwave or a frosty winter night, your Simba duvet keeps you thermally balanced.

🌿 Eco-Conscious Simba Renew Bio™ Fill

The duvet is filled with Simba Renew Bio™, a 100% recycled and biodegradable alternative to synthetic polyester. This sustainable fill mimics the feel of feather and down while offering:

• Breathability

• Lightweight softness

• Excellent loft and shape retention

It’s also hypoallergenic, making it safe for allergy sufferers and better for the environment. Sleep well and sleep responsibly.

💨 Breathable & Lightweight by Design

Thanks to Simba’s hybrid build and airflow-maximising stitching, the duvet remains light and breathable even when both layers are combined. No heavy weight. No bulky layers. Just cloud-like softness and all-over comfort.

🛏️ Available in 4 UK Sizes:

Perfectly sized to fit all standard UK bed frames and mattress sizes.

🧼 Easy-Care & Machine Washable

Both duvet layers are machine washable at 40°C, and they dry quickly. The materials resist clumping and maintain their shape after repeated washes. Built for everyday life, just like your sleep should be.
