King Size Duvets

The Simba king size duvet is a super-soft, duvet that feels luxurious and is designed to help keep you at a comfortable temperature.  Even during hotter summer nights, our innovative Stratos® ‘cool-touch’ technology will help keep you feeling fresh but cosy, while our Simba Renew® fibre fillings provide silky down-like softness.  

It might be big, but we stitch the super-soft filling evenly into square pockets so the comfort reaches every corner. That means no more lumps and bumps in the night and a soothing night’s sleep.

There’s also free delivery and returns and a one-year guarantee on all our Simba Hybrid Duvets. 

You might not realise it, but all the king size duvets for sale here at Simba are packed with an array of innovative technology designed to support a quality night’s sleep.

• Stratos® ‘cool-touch’ technology is designed to offer an instant feeling of freshness sensation and to support the diffusion of excess heat.
• Simba Renew™ clusters are the tiny 3D clusters that create the silky and smooth down-like softness inside every Simba duvet. We comb, multi-layer and fold them like never before to create an incredibly light duvet with a wonderful, airy warmth.
• We use a 20% blend of incredibly fine Modal fibres in our 3-in-1 Duvet. Derived from natural wood pulp, it’s renowned for its ability to actively wick moisture away from the body to help keep you dry and comfortable throughout the night. 

Size isn’t everything when choosing your duvet. The tog rating, which indicates how warm the duvet is, is pretty important too. A higher tog is better in the colder months, while a lower tog is cooler in the summer.

• The Simba Hybrid® king size duvet is lightweight but still delivers an impressive 10.5 tog, making it a great all-season choice for cold sleepers.
• Our Simba Hybrid 3-in-1 Duvet has something for every season, with separate 3.5 tog and 7 tog duvets you can join together to create a 10.5 tog duvet for colder, wintry nights.
• Simba Summer Hybrid Duvet - A lighter 4.5 top duvet filled with down-like Simba Renew Bio ™ fibres, designed to offer gentle cooler comfort. It’s a must for warmer months or anyone who gets too hot at night.

Simba king size duvets are L220cm x W225cm, which is the standard duvet size for a UK king size bed. King size beds are a popular choice if you have the space and are even more luxurious with a Simba duvet on top.

We also sell superb Single Duvets, Double Duvets and Super King Size Duvets.

You can wash your Simba king size duvet in your washing machine at 40oC and tumble dry it on the lowest heat. You’ll find a label on your duvet with washing and care instructions. We recommend using a 9kg washing machine or larger to get your king size duvet really clean. Its larger drum size will let the water and detergent follow through the duvet evenly.
