About Slumbersac Sleeping Bags

Babies and toddlers benefit from a better night’s sleep at a constant temperature, while parents can rest assured too in the knowledge their children are sleeping safely. Slumbersac sleep bags can be easily washed and dried and can be taken with the child for overnight stays.


All Slumbersac baby sleeping bags are of exceptional quality and are exclusively designed for Slumbersac. Made with 100% cotton and lined with 100% pure cotton, they are all rigorously tested and can be both machine-washed and tumble-dried. The filling is made from quick dry soft polyester fleece, which helps to prevent allergies and stops the sleeping bag losing shape and becoming 'lumpy'.


Research shows that when using conventional bedding babies tend to get too hot or too cold. Slumbersac baby sleep bags ensure babies remain at a constant temperature and eliminate the need for any other top covers. Simply put your baby into his sleep sack when he is ready for bed and then pop him into a Moses basket or cot. Do not use any blankets or duvets. Staying within the sleep sack minimises disruption when feeding during the night, and being snug also means they are more likely to go back to sleep if they do wake up unexpectedly.


The tog rating or weight of a sleep sack determines its thickness and therefore how warm it keeps your child. The higher the tog rating (weight) the warmer the sleeping bag. Please follow our recommendations on the table below to determine which tog is the best one for you. The decision depends mainly on the nursery temperature.

Our table also suggests what your baby should wear, depending on the temperature and weight of the bag. These are guidelines only - you should always check your baby to make sure they don’t overheat. Remember it is better to be cool than hot and it is quite normal for the baby’s hands and arms to be cool. Feel the nape of your baby’s neck – if it is damp then your baby might be too warm.



Slumbersac baby and children sleeping bags are available in six sizes, ranging from newborn babies right up to ten-year-old children!

When choosing a size, remember that your child should be able to kick and wriggle freely in the sleeping bag. Ideally babies' feet should be at 3/4 of the sleeping bag, leaving the bottom quarter of the sleeping bag 'empty'.


Our Slumbersac sleeping bags with feet are available in five sizes, ranging from 12 months old toddler up to six-year-old children!

When choosing a sleeping bag with feet, remember that your child should be able to walk around in them during the day and put their feet inside the sleeping bag at night. To choose the right size sleeping bag with feet measure your child and their height + 10cm = sleeping bag with feet size.
See the illustration below for more information about the measurements of our sleeping bags with feet.


Your child's safety is our priority!

As the parent of a young baby, it is natural to worry about your child’s health. A particular concern for many mums and dads is sudden infant death syndrome (SIDS), which is also sometimes referred to as cot death. The good news is that SIDS happens very rarely, and this is partly due to the ongoing research and education programs that have done such as great job over the last few years in identifying the causes of SIDS and in getting practical advice out to new parents. Some of the key risk factors that studies have identified include:

  • Sleep position. Experts advise that the safest place for babies to sleep is on their backs in a cot in the same room as their parents. It is best to avoid sleeping with your baby in your bed, particularly if you are very tired or have been drinking alcohol.
  • Smoking. Smoking around new babies increases the risk of cot death, and should be avoided.
  • Blankets covering the baby’s head. Blankets and sheets can cover a baby’s head if the baby wriggles down under their bedding, or if the bedding comes loose in the night. Similarly, other unnecessary items in the cot, such as cot bumpers, pillows and toys can increase the risk of smothering.
  • Over-heating. Babies can’t control their body temperature as well as adults, and using too many blankets can cause them to over-heat. The ideal room temperature for a sleeping baby is about 18 degrees centigrade. To help to maintain this temperature, do not set the central heating too high, and avoid placing hot water bottles and electric blankets in your baby’s cot.

Happily, it’s easy to put this advice into practice by making a few simple changes. Baby sleeping bags can help to keep babies safe too. In a sleeping bag, your baby can wriggle about as much as she likes without accidentally covering her head. Furthermore, a sleeping bag promotes a stable body temperature, and you can use different weight sleeping bags at different times of the year to ensure that baby remains safe and cosy at all times, neither too hot nor too cold. A grow bag can also help to ensure that your baby remains on his back because the bag makes it harder for him to roll over.

When choosing a sleeping bag for your baby, you need to make sure that you get the right weight and size. The weight or thickness of a sleeping bag is indicated by its tog value; the higher the tog value, the thicker the bag. The general rule here is that you should use thinner sleeping bags in the summer and thicker ones in the winter.

Remember too that the clothes that your baby wears will affect their body temperature. Do not use blankets with sleeping bags because this might make baby too hot, and use a thermometer to check that the room is the right temperature

As well as the choosing the right sleeping bag weight, you should take care to select the right size sleeping bag for your child. If the bag is too large, your baby can slip into it and their head might become covered. Additionally, babies in sleeping bags that are too big will lose body heat more quickly. On the other hand, a bag that is too small will be uncomfortable and might restrict movement too much, which will lead to restlessness and less sleep for both baby and parents! Slumbersac sleeping bags are available in six different sizes, and are suitable from birth to six to ten years old.
