What is the Best Tog For All Year Round?
The tog rating of a duvet could be the difference between a chilly, sweaty night's rest and a peaceful one. Knowing the tog of your duvet is crucial to have a relaxing night's rest throughout the year.
For summer, opt for a duvet that is lighter, around 7.5 tog. This will let you remain cool and comfortable during the hot summer evenings.
Winter
As autumn approaches is the perfect time to swap your summer duvet out for a heavier winter one. Although you may be tempted to buy one of the warmest duvets on offer - especially in the case of a cold sleeper or live in a cold climate - it's best to put off switching until the average nighttime temperature begins to fall below 10 degrees Celsius.
The tog rating of a duvet or thermal overall grade (TOG) indicates how it insulates warmth. It is typically expressed as a number ranging from 1 and 15. The higher the tog rating, the warmer the duvet.
The TOG is a measure that's based upon a globally recognized testing method. It evaluates the effectiveness of is wicking off moisture, retaining heat, and keeping your body temperature in check during the night. This technique can also be used to regulate other bedding items like doonas and Pyjamas.
The filling type used in a duvet has an impact on its tog rating as well as how comfortable it is to sleep under. For instance, synthetic fillings are less permeable than natural fibres like feathers and down. This can cause overheating for hot sleepers. A top-quality feather and down duvet, or merino wool duvet however provides excellent insulation without compromising on breathability, which allows you to regulate your body's temperature while you sleep.
If you're a cold sleeper in a warmer bedroom this duvet from the brand Piglet in Bed might be a good option. It has a medium-tog rating but is super soft and plump due to the filling of merino wool. This duvet from Piglet in Bed is a great choice to get sleeping in a warmer space. It has a medium-high tog rating and is supple and soft due to its merino filling. It's also simple to wash and has minimal shrinkage. This makes it a good investment that will last throughout the year.
Duvets for children are also likely to have a TOG rating. The first duvet for a child is usually lightweight, and should not exceed 4 tog. This will help keep the child warm without overheating them or hindering their ability to breathe. Based on the temperature of their bedroom and the climate where they live, they may be ready for a larger duvet by the time they reach two.
Spring

As the weather begins to get colder and the nights get darker it's time to switch your duvet to a higher tog rating. This will keep you warm and comfortable all night, which will help you sleep more deeply. However excessive warmth can cause you to sweat throughout the night, which could affect your quality of sleep. One method to determine if you are too hot is to feel the material of your duvet. If it's uncomfortable or prickly, this can indicate that the duvet has a too high tog rating.
We suggest a 10.5 tog for the seasons of Spring and Autumn, as this will be warm enough to keep you warm but not too warm. This will let you rest comfortably at night and help regulate your body's temperature.
We have a variety of duvets with a lightweight design to those looking for a lighter choice for summer. These duvets are made of light fabrics and fillings which will keep you cool at night. This will ensure a restful sleep and give you the best sleep possible.
We recommend a duvet which has a low weight like 4. A heavy duvet could cause young children to overheat, which could adversely affect their sleep. We also have a selection of all season duvets which are ideal for children as well as adults. They are made of two separate duvets that can be buttoned together to create a flexible solution for the changing seasons.
The tog of a mattress doesn't necessarily mean the quality of the product, since it only measures thermal resistance and not the durability or feel of the duvet. A duvet with a higher tog rating may initially test as superior, but it could lose its insulation as time passes and lose its effectiveness over time. It is therefore essential to purchase a duvet of high quality from a reputable supplier. This will ensure that your duvet stays warm and comfortable for the duration of time you own it.
Summer
As the weather gets warmer you'll need a light duvet that will keep you cool without causing you to overheat and disrupting your sleep. A 7 to 10.5 tog duvet is suitable for most people during the Spring and Summer months, especially in the case of an insulated bedroom.
You can always swap to a lighter option as the nights become cooler however, you might prefer to keep warm during the Winter with a heavier duvet. If so, this medium-weight British alpaca duvet is the one for you. It's not quite as thick as the 10.5 tog duvet, but is still a great insulator.
Natural fillings are great for keeping cool, as they're more insulating than synthetic options such as hollowfibre or polyester. They're also breathable, and allow your body to release any excess heat. This helps keep you cool and comfortable. This merino wool duvet from Piglet in Bed includes this feature, and although it doesn't boast any specific tog rating, Piglet in Bed estimates the range to be between 8 and 10 tog.
It's possible to buy a duvet for you and your partner if you have very different sleeping habits. This duvet with a half and a half from Slumberdown might be the answer; it has one side that's cool 4.5 tog and the other that's warm 10.5 tog. This allows whoever sleeps hot to sleep on the lighter side, while whoever feels cold can stay warm under the warmer.
A 3-in-1 duvet is another option. It'll comprise an edgier, 3.5 tog duvet for summer and a heavier 10.5 tog duvet for autumn/winter that can be hung together. This lets you easily change between seasons without having to dig out duvets from the loft. It's an excellent option for the erratic UK weather! Alternatively, standard tog duvet can purchase this cozy goose down duvet to keep you warm and toasty all year long. It's neither too heavy or warm, and comes with a lovely soft texture.
Autumn
The ideal duvet is vital to rest well at night. The right weight for your duvet your needs is dependent on many aspects, including your body's temperature regulation as well as the conditions in which you live.
The tog rating is an important factor to consider when buying duvets, as this is an indication of how well the duvet holds heat and keeps you warm and snug. Tog ratings are available from 1 to 15. Lower togs provide more cooling, while higher ratings provide more warmth.
In general, lighter tog duvets will be more suitable for summer months. The duvet is more lightweight and ventilated, which means you won't get too hot while sleeping under it. Duvets with higher tog are great for autumn and winter, because they're warmer and will keep you cosy during these colder temperatures.
If you are looking for a duvet that can keep you warm throughout the seasons, look for an all-seasons option which is comprised of two lower and higher-tog duvets that can be fastened together to suit your requirements. For instance the Simba Sleep Hybrid 3-in-1 duvet (PS349 for a double, Simba Sleep) is comprised of a 3.5 tog summer duvet and a 7-tog autumn/spring duvet which can be sewed together to create a 10.5 tog duvet to keep you warm on cold nights.
If you don't have the money to buy multiple duvets then a 10.5 tog will be a good choice for all seasons. Hotels generally choose this tog rating due to the fact that it provides a good amount of insulation without being overly heavy. This is due to the fact that hotels are aware of the allergies of their guests and are keen to ensure that the bedding they provide are suitable for everyone. They don't want to have the storage of multiple duvets for different seasons. In addition, they're looking to offer their guests the most comfortable experience possible.
