Poor quality product, poor customer service

Poor quality product. After using for just over a month the neckline completely separated due to faulty stitching. After contacting them due to it being a manufacturing fault they offered me a 50% refund to stitch it myself. When I asked for a replacement (and I’d send the faulty one back once I’d received the new one) they stopped replying to my emails.

We’re really sorry you feel this way as this doesn’t reflect how your case was handled.

When you contacted us about the seam issue, we responded promptly and offered two solutions in line with our warranty policy: a replacement once the item was returned using our free returns label, or a 50% refund if you preferred to keep the sleeping bag.

As confirmed in our email correspondence, you chose the 50% refund option so you could purchase another sleeping bag, and this refund was processed for you straight away. At that point, the replacement process was cancelled, which was clearly explained in our message. We did not stop replying and the case was closed once the agreed resolution had been completed.

We always aim to resolve concerns fairly and as quickly as possible, and we remain here to help if you have any further questions.

We are sorry to read this, as it certainly does not reflect the service we provide. However, you seem to be based in Switzerland and Slumbersac UK does not currently ship to Switzerland. It appears this purchase may not have been made through our shop.

We take customer service very seriously and always work closely with our customers to resolve any delivery or payment concerns quickly and fairly. If you believe your order was placed with Slumbersac UK, please contact our customer service team directly with your order number and the email address used at checkout so we can investigate properly.

Good customer service, shame about the sizing

I bought 2 sleepsacks from Slumbersac 0-6 and 6-18 as I was unsure which would be the best fit. The items were lovely and thick for winrer and seemed really cosy. Unfortunately they were both too big. My baby is 6 months old and so should have fit in the 0-6month size based on his length. The length fitting was great but the neck opening and shoulders was too big. I contacted Slumbersac for a return and Anneke on customer services was great. When I contacted her as the refund was taking a bit of time with it being Black Friday and Christmas she processed the refund for me so I didn't have to keep waiting. despite the length being great, the neck opening was too wide so I returned them. Anneke on customer services was great with communicating with me and chasing the refund.

Overall great experience just a shame the sizing was off

Thank you so much for your lovely comments about the quality of our sleeping bags and our customer service team. We’ll be sure to pass your kind words on to Anneke. 😊

We’re sorry the fit wasn’t quite right for your little one. We completely understand how important a secure fit around the neckline and shoulders is. We do always recommend choosing our sleeping bags based on baby’s height and size rather than age, as little ones grow at such very different rates.

Don't buy here

Got aprons for my 18 month old and it had 18 to 24 months and it was too small. Not a good website,I would not buy off them again. False sizing and also says its a Ireland website when its based in the uk

Thank you for contacting Slumbersac UK.

It seems you may have bought a product from Slumbersac Ireland. However, regarding the product, Slumbersac doesn't sell aprons so I wonder if there may have been a mix-up with another item or store. If you meant our bibs, these are designed for 6–24 months, though fit can vary depending on each child.

Also, to clarify, Slumbersac Ireland is not based in the UK. Our European head office is in Germany and we have teams working across Europe, including Galway, Ireland.

AVOID- REFUSING TO REFUND

AVOID- REFUSING TO REFUND

I ordered 3 sleeping bags with feet. Unfortunately they stank of a weird plastic smell upon opening. I assumed the smell would dissipate upon washing so I washed them. The smell was still there two washes later. My child has allergies and a skin condition and therefore I cannot risk him sleeping in something which could be contaminated with an allergen.
I requested a refund and the most rude and unhelpful Anneke has not only refused, they have refused for me to speak with management. In the UK it’s illegal to refuse to refund faulty goods so this is breaking the law. I will be escalating this from a legal perspective, but I suggest you AVOID this horrific company.

We completely understand how concerning it must be to notice an unexpected odour, especially when your child has allergies and sensitive skin. Please rest assured our sleeping bags are made from natural, certified materials - our 0.5 TOG sleeping bags are made from a soft blend of 50% bamboo viscose and 50% cotton muslin, which is naturally breathable and gentle on sensitive skin.

All of our sleeping bags are thoroughly tested for quality and safety, and we sell thousands of them worldwide each year. This is the first time we have received feedback about an unusual odour like this and your request was reviewed carefully by both our customer service and management teams.

We have very strict hygiene policies in place to protect all customers, which means we’re unable to accept returns of washed or used sleeping bags. This is standard practice for baby and children’s sleepwear and is in line with industry hygiene guidelines.

We’re sorry we couldn’t reach the resolution you hoped for.

I’ve ordered a few sleepsacks from this company and love every single one. My little one sleeps the whole night when in his 2.5 tog with sleeves because he’s so comfortable. Delivery is always super quick too!

Arrived very quick and lovely quality

My order came the next day. It was dispatched immediately and the quality seems great. They are sized very big. I got a 90cm for my 2yo daughter and it's huge but fits well.

Don't buy early for Christmas

At the request of my daughter-in-law I ordered a summerweight Slumbersac as a Christmas present for my granddaughter. I wasn't sure of the delivery times so ordered it on 22nd November and was surprised to receive it on 24th November. I didn't get to see my granddaughter until 29th December when I saw the unpacked Slumbersac, size 18 months to 3 years it was huge and it would have fitted a 5 year old. I realised I was just outside the normal 28 day return window so emailed Slumbersac thinking they would be sympathetic as it was the Christmas period. I got very short shrift when they replied 5 days later and was told there were no exchanges/refunds outside 28 days. It was very disappointing and they have lost my future custom.

Sorry to hear you weren't happy with our returns policy. We do give 28 days to allow customers to change their mind in this time and unfortunately you were outside of the returns window. I'm not sure which baby sleeping bag you have purchased but usually the 18 months to 3 years baby sleeping bag comes with velcro to reduce the length size if you should so wish. Our sleeping bag size length is generous because your child should be able to kick and wriggle freely in the sleeping bag, ideally with babies' feet at 3/4 of the sleeping bag, leaving the bottom quarter of the sleeping bag 'empty' for freedom to move. Sleeping bags should never be purchased on age alone as this can differ so much between children. We have a size guide with advice on our website to help: https://www.slumbersac.co.uk/sizes/

Sizing is really off

Sizing is really off. brought the 70cm with feet for my baby 7months old and 70cm tall, she's now 10 months old and 72cm tall and her legs have never stayed out of the sack for longer than 5 minutes. she's has chunky legs too but the socks on the sack with feet just do not stay on at all meaning her legs just get caught in the sack and it's completely pointless spending so much for a sack with legs when the feet don't stay out. It says a lot that there's no reviews on their website that they haven't curated.

Thank you for taking the time to give your feedback. We recommend our sleeping bags with feet are worn from approximately 12 months old so little ones can sleep, crawl, walk and play in them. Hopefully you will notice the difference in a couple of months time when she is older. You can find many positive reviews about our sleeping bags on Facebook and Feefo as well as our website.

Great company and great products

Made a mistake when ordering this company sorted it out quickly and efficiently and the product itself is excellent beautifully made great designs and generous sizing having an autistic toddler who will not accept a blanket or duvet so the sizes these sleeping bags go up to have saved me alot of worry in the future thank you :)

Amazing customer service and amazing quality

I could not recommend Slumbersac enough! The customer service was second to none. I originally ordered to wrong size and emailed to make changes and Anna replied within minutes to cancel my order, she was so helpful. I then got the right size and the quality is amazing.. My daughter loves it.

Badly fitting socks and terrible customer service.

I have bought a few sleeping bags from this company, and was generally satisfied with the quality. They are expensive but apparently sustainable minded. I have since bought socks and was very disappointed with the product and customer service. The socks are marketed 12-18 months, and at 14 months they are way too tight, yet my toddler is on the 50th percentile in height and weight, so is very average. I sent them a picture and a note, and they basically said after some exchanges of emails that I needed the size up. Yes …I had gathered that! But I am not going to spend more money on a company that acts like you do. No apology, no “we will take on board your feedback”. They said I could have given them back, and I replied that I didn’t know they were too tight until I saw other mummies with babies with better fitting socks. They never replied. The socks were £5 in comparison with their sleeping sacks which cost over £40 …worth losing a customer over? Apparently yes. Ps their reply on trustpilot is that there needs to be a fault with the sock. Surely a sock that’s too small for the target audience is a design fault? A sock which cuts of circulation…hmm

Thank you for your feedback. We are sorry that the socks were not the size you expected for your little one. Unfortunately the socks had been worn by the time you notified us and, as with most retailers, we cannot accept returns on used products unless there is damage or a fault. We have, of course, passed on your feedback to our product department.

Brilliant bags Iv used them since my first child, they wash and wear really well. I love they go up to larger sizes as my sons autistic and it’s now a part of my routine. Customer service was so helpful when I had lots of questions about size and materials.

Awful service

I have a few slumbersac’s they are ok if you get them in the sale definitely not worth it at full price. Customer service on the other hand is DISGUSTING. Firstly they processed the order twice and I had two pending payments on my bank account and was told because they were pending i’d need to call my bank as it was my issue not theirs! Then waiting over a week from ordering, I emailed to find out we’re the order is and they said the payment was still pending and I should ring PayPal. Never in my life have I had to chase around after placing and order online using PayPal. PayPal said there was no issues then I “coincidentally” get a snotty email from slumbersac to say it had gone through and please look at the screenshot dated today blah blah blah…but it was dated 3 days earlier, just awful don’t waste your time your baby will have grown out of the size you ordered by the time you get it LOL

Great items and fab customer support

This is my second purchase from slumbersac now, my first was a sleep sac for my little boy and I finally took the plunge to spend on myself and bought the adult sleeved sleep sac. Wish I'd done it sooner having breastfed/co-slept for last 20 months and never being warm or comfortable enough! I hesitated on the cost, I don't usually spend much on myself it feels wrong(?!) I think that's a mum thing. But it really is worth every penny.
I emailed the company on Monday morning as there was an 'issue' with the sleeve poppers, I actually got a phone call from a really helpful, friendly lady who sadly I can't remember her name. But she patiently talked through it with me and there was no actual issue just me not properly checking and reattaching the sleeve! She was very helpful though and had already contacted a local seamstress company for a quote if there was an actual issue, that is going above and beyond to me. But yes, there was no issue it just turned out to be a sleep deprived misunderstanding on my part. But based on customer service alone I'd definitely come back to this company.

Absolutely nightmare of a sleeping bag

Absolutely nightmare of a sleeping bag. The zip on the sleeping bag keeps getting stuck and I end up waking the baby if I am trying to get them out of the bag while they are sleeping. Completely unhappy and disappointed with the product. Not worth the money. The bags worth half the price of this one work much much better.
When I contacted the company I was told that I can return it if its unused and unwashed which it obviously wasn't as I washed it before using it with the baby. What a nightmare and utter waste if money. DO NOT RECOMMEND AT ALL!
