As the seasons change and we come into the colder months, I was excited to test out one of Simba’s high-tech duvets. The Simba Hybrid Duvet all-rounder 10.5 tog in a super-king size arrived, I can confidently say that it’s a great investment for anyone looking for a versatile and comfortable duvet. In my Simba duvet review, I will go deeper into why this one needs to be the season duvet to have! The duvet is double-sided, with one side being cool and the other warm, making it perfect for use all year round. Plus, it’s hypoallergenic, which is a great feature for those with allergies.

One of the standout features of the Simba Hybrid Duvet is its flexibility for all-year-round use. This duvet is perfectly balanced at a 10.5 tog, it will keep you warm on chiller nights and cool on those warm summer nights. And with it feeling light on your body, there is no clammy feeling. It is soft with a fluffy feel just like a cloud! It’s the right duvet for me and one of the best duvets on the market.
Overview of Simba Hybrid Duvet
As someone who values a good night’s sleep, I was excited to try out the Simba Hybrid Duvet. Last month you may remember we reviewed the Simba Hybrid Pillow, which is doing a great job for the perfect Simba sleep! Back to the duvet, it promises to be lightweight, hypoallergenic and made using sustainable methods. It also uses space-inspired technology to regulate your body temperature, ensuring you stay comfortable all night long.
The Stratos® technology used on one side of the duvet; makes the fabric feel instantly cool to the touch, as well as enabling it to react to your body temperature, dissipating any excess body heat to keep you cool and dry. The other side is a pure better cotton cover that ensures breathability and airflow.
The Simba Hybrid Duvet is available in different sizes: single, double, king and super king. It has a tog rating of 10.5, which makes it suitable for use throughout the year. However, if you tend to get very cold at night, you may need to pair it with an additional blanket during the winter months.
One of the things I appreciated about the Simba Hybrid Duvet is that it is hypoallergenic. This means that it is less likely to cause allergies or irritations, which can be a real problem for some people. The duvet is also made using recycled materials, which is a nice touch for those of us who are environmentally conscious.
In terms of comfort, the Simba Hybrid Duvet delivers. It is soft and fluffy, without feeling too heavy or cumbersome. The Stratos® technology really does work, too – I found that I stayed at a comfortable temperature throughout the night, without getting too hot or too cold.
I would recommend the Simba Hybrid Duvet 100 per cent to anyone looking for a comfortable, sustainable, and hypoallergenic duvet that will keep them at the perfect temperature all night long.
It comes with free delivery in 3 working days, which is a carbon neutral delivery!

Unique Features of Simba Hybrid Duvet
As someone who has used the Simba Hybrid Duvet, I can attest to the fact that it has several unique features that set it apart from other duvets on the market. Here are some of the features that I found to be particularly noteworthy:
Temperature Control
One of the most impressive features of the Simba Hybrid Duvet is its ability to regulate temperature. The duvet uses technology inspired by NASA to ensure that you stay at a comfortable temperature throughout the night. This means that you won’t be too hot or too cold, regardless of the season or your body temperature as it dissipates the excess heat. This is particularly useful if you are coming up to or in the menopausal stage.

Menopause can affect sleep in various ways. The hormonal changes during menopause can cause hot flushes and night sweats, which can disrupt sleep. The Sleep Foundation suggests that other common sleep problems during menopause include insomnia, sleep-disordered breathing, and other mood and sleep disorders. Sleep disorders during menopause can range from 16% to 60% of people depending on the stage of menopause. Women can experience poor, disrupted sleep due to hot flushes and other sleep disorders that may impact both nighttime and daytime quality of life. As well as a cooling mattress, the Simba Hybrid Duvet, which has the cooling effect, may help alleviate the discomfort caused by hot flashes during menopause, allowing for a more restful sleep and increasing the quality of your sleep. It’s a game-changer!
Materials
The Simba Hybrid Duvet is made from high-quality materials designed to last. The duvet is 100% hypoallergenic, making it safe for people with allergies. Additionally, the duvet is fully machine washable and can be tumble-dried, which makes it easy to keep clean and maintain. You will need a large washing machine for the super king size!
The three layers of the duvet are:
1. Better Cotton outer with Stratos® heat control technology – an advanced material.
2. Super-soft, sustainable Simba Renew Fibres – Simba Renew Bio™ is kinder to the planet and offers perfect, non-clammy warmth.
3. Better Cotton cover (plain side) – Pure Better Cotton cover ensures breathability and airflow.
The quality duvet arrives in a sturdy recycled storage bag. This has many uses as my kids have discovered!

Comfort and Softness
The Simba Hybrid Duvet is incredibly comfortable and soft. The duvet is designed to feel like those down duvets, without the use of actual down feathers. This means that you get the same level of comfort and softness without any of the ethical concerns that come with using duck feather or similar.
I’ve really found the Simba Hybrid Duvet to be an excellent choice for anyone in need of a high-quality, durable duvet that can be used year-round. With its temperature-regulating technology, high-quality materials, and exceptional comfort, the Simba Hybrid Duvet is definitely worth considering if you’re in the market for a new duvet. I can’t sing its praises enough!
Oh, it’s also worth mentioning the square quilting! They have been stitched into squares to prevent clumping! There is nothing worse than a clumping duvet during the night and you get cold feet!

Price and Value for Money
Price point: As someone who is always on the lookout for the best deal, I was initially hesitant about the price of the Simba Hybrid Duvet. However, after trying it out for myself, I can confidently say that it is worth every penny.
The Simba Hybrid Duvet is definitely not the cheapest option on the market, but it is a high-quality product that is built to last. Made with premium materials and innovative technology, this duvet is designed to provide superior comfort and temperature regulation all year round.
In terms of value for money, the Simba Hybrid Duvet is an excellent investment for anyone who wants to improve their sleep quality. While it may be more expensive than some other duvets on the market, its superior quality and innovative design make it well worth the price.
