Amazing product. The fastest delivery time as well. We couldn't be happier knowing our daughter is nice and cosy at night time.

We have several of the Slumber Sac brand and we always find their quality warm/cool as needed and of beautiful feel and design.

Fast delivery and super cosy for my 18 month old. I love that he can run around when he wakes.
Reply from Slumbersac Ireland
Thanks so much for your lovely review. 😊 We're delighted to hear your little one is staying warm and cosy in his sleeping bag with feet.
I'm going to mark them as one star for the main point that they don't show item reviews on their website.
Additionally, as stated by others, the sizes are unfortunate. I find the 0 to 6 month size very good but once past that, the sacks become comically large. It's very hard to accurately measure the length of a baby so you have to go with their age range recommendations. Then when the kiddo starts approaching say 90% the length of the sack, I find the neck opening gets too small so then you're back sizing up to the next comically large size.
Another gripe I have is that they've a more expensive organic cotton option but the filling is still polyester. I would have loved an option with a more natural filling.
I saw some reviews here mention a dangerous zip as it closes at the top, they seem to have changed that. With the sack I just got the zip closes at the feet. A bit trickier to get on but it's my preference as it's safer.
It's very close to be being a great company. Just more transparency about reviews and size improvements should really do it. The current lengths are based on being rounded to the closest 10cms, which isn't accurate and it's not how people shop since they can't measure the length of their baby accurately at home.

Thank you for taking the time to share such detailed feedback. We really appreciate it and are pleased to hear there are things you like about our sleeping bags.
We've recently been making improvements to our website, including updating our customer review system. Reviews will be returning very soon, as we know how helpful they are when choosing the right sleeping bag. We have thousands of happy customers and are always keen to share their experiences.
Regarding sizing, our sleeping bags are deliberately generous at the bottom to allow babies plenty of freedom to move comfortably while sleeping. Ideally, your baby's feet should reach around three-quarters of the way down the sleeping bag, leaving the bottom quarter empty. The neck and armholes should always fit securely, and we recommend choosing a size based on your baby's height rather than age as babies can grow at such different rates.
We also understand your preference for natural fillings. Our organic cotton sleeping bags have an organic cotton outer and lining, with a specially designed, breathable polyester filling. Its loose structure allows air to circulate while providing warmth. It's also durable, easy to care for and allows our sleeping bags to be washed at 60°C – something many parents really appreciate! That's why we've carefully chosen this filling, to offer a balance of warmth, breathability and everyday practicality which cotton or wool filling can't match.
Thank you again for your honest feedback. We're always looking at ways to improve our products and website, and comments like yours are genuinely helpful.
We started using these sleeping bags with my little girl when she was 18 months old. She loves it and when she started standing up in her cot they were convenient to use and felt safer than tripping in the standard sleeping bags. It’s also nice that she can walk around in it. They’re quite big so don’t size up. The patterns are lovely. The quality is fantastic. Ours are washed and dried multiple times a week and have lasted better than any other sleeping bag we have used. We’ve had winter and summer sleeping bags. Would highly recommend.

What a lovely review to read. 😊 We're delighted your little girl loves her Sleeping Bags with Feet and that they've been so handy as she's grown more active. It's especially great to hear how well they've stood up to all that washing – we know how important that is with little ones! Thanks so much for recommending us and for sharing your experience with other parents.
Good quality sleep sack, but I have concerns about the zip placement. The zip closes at the top and my baby is able to get hold of it and put it in his mouth. There is a zip cover, but unfortunately it doesn’t prevent him from accessing the zip pull. I’m concerned about the potential choking risk and would feel much safer with a design where the zip closes from the bottom instead. As a result I won’t be using this product.
Reply from Slumbersac Ireland
Thank you for sharing your feedback. We're pleased to hear you're happy with the quality of your sleeping bag, but we're sorry to hear about your concerns with the zip placement on this particular sleeping bag.
Our Baby Sleeping Bags with a central zip have a protective fabric cover designed to keep the zip pull tucked away. We understand your concern if your little one has managed to access the zip despite this cover, and we take feedback about safety very seriously.
We also offer Baby Sleeping Bags with a zip that runs around the side and fastens under the arm, which may be a more suitable option for your little one. Alternatively, our Sleeping Bags with Feet in baby sizes have a zip that fastens at the bottom for easy nappy changes, keeping the zip pull away from your baby's face.
Please do get in touch with our customer service team so we can look into your concerns and help you find an alternative that you're happy and comfortable with.
I had a hard time parting with the money and didn’t order for ages because it is an expensive buy but now i actually wish I’d bought it sooner.
I was always freezing Co sleeping and breastfeeding but the slumbersac is awesome and really great quality too.
I’m not sure how but it got to me in 22 hours after ordering

We're so pleased to hear your Slumbersac COZY adult sleeping bag has made those chilly nights a little more comfortable. 😊 We completely understand that it's an investment, so it's lovely to know you feel it's been worth it. Thanks so much for sharing your experience and we hope you enjoy many more cosy nights ahead.
I purchased sleeping bags from Slumbersac and I’m really pleased with the quality. The designs and patterns are absolutely lovely and feel well made.
At first, we weren’t sure about them, so we only purchased two back in September 2025. However, we’ve been so happy with them that we’ve now ordered two more for the upcoming summer for our little baby.
This time, we chose the 12–18 months size, and we’re hoping they’ll be just as great as the 6–12 months ones we originally bought. So far, we’ve had a really positive experience and would definitely recommend!
Reply from Slumbersac Ireland
It's so lovely to hear you've come back for more sleeping bags! 😊 We're delighted that you've been happy with the quality and designs, and hope your little one will be just as comfortable in their ones. We really appreciate your continued support and recommendation. It means a lot to us. 💛
Slumbersac website recommends size 110cm for 18 month to 36 month old toddler. It arrived today and to say it would fit an adult is no exaggeration! It is huge! We would have returned it but our 9 year old took a shine to it and wants it for herself, she'll no doubt grow into it in a few years as its also too big for her.. a 9 year old. Shocking size references, avoid!!!
Reply from Slumbersac Ireland
Thanks for taking the time to leave your feedback. We're sorry to hear you were surprised by the size of your sleeping bag.
Our 110cm sleeping bags are designed to grow with your little one, so they have a handy Velcro fastening at the back that allows you to fold up the extra length until your toddler grows into it.
They're also intentionally roomy at the bottom to give little ones plenty of space to move about comfortably while they sleep. Ideally, your child's feet should reach around three-quarters of the way down the sleeping bag, leaving the bottom quarter free for movement.
We always recommend choosing a size based on your child's height rather than their age, as little ones grow at such different rates.
We hope this helps explain the generous sizing a little better, and if you need any advice, our customer service team will be more than happy to help. 😊
Super fast delivery. Product is beautiful quality and exactly as described. Love that the company supports sustainability and supports different projects around the world. Will absolutely order again.

I love these sleeping bags but unfortunately from age 12/15 months up the design totally fails. A toddler will try and succeed in zipping open their sleeping bag as the zipper closes at the top and not the bottom of the sleeping bag. It is simply dangerous to use these sleeping bags for toddlers.
Reply from Slumbersac Ireland
Thank you for your feedback. 😊
Our smaller sizes have a zip that closes at the bottom for easy nappy changes, while our larger sizes have a zip that closes at the top, with a protective zip cover.
We do appreciate that some little Houdinis still manage to work out how to unzip their sleeping bags, despite our best efforts to keep the zip tucked away! Some parents have found that putting the sleeping bag on backwards does the trick until their little one grows out of this phase.
We really appreciate you sharing your experience and certainly take your feedback on board.
