I recently purchased my Kosi and really like it, however within the first 7 days some of the stitching came apart. I emailed customer service and was offered a $10 refund (to go towards getting it repaired locally) or $20 to spend another time. I found this to be a very poor response, and will likely not buy any further products from Kosi, you can tell by the photo the stitching was done poorly.
Very comfortable.
Hi Matt, we're so glad to hear that! Comfort is what we’re all about <3
I don't have endometriosis, but I do have an issue with my colon and often find that using a wheat bag gives me more relief than pain killers. I recently discovered the Kosi, recommended by an endometriosis sufferer and it was fantastic. Being able to wrap it around my lower abdomen provided so much relief. Thank you.
Hi Judy, thank you so much for sharing this, we’re so glad Kosi has been able to bring you real relief! It means so much to hear that it’s helping support your body in the way you need. Sending you so much love, and we’re truly grateful you found us! <3
It is comfortable, looks great and an awesome design but ..... it simply does not hold the heart which is VERY disappointing. Started heating it as per the instructions but now, l have to heat it for 2 minutes, readjust and turn over then another 2 minutes and sometimes more then within a couple' of minutes, it is time to reheat. For the price, and sorry to say, l would not recommend it which is disappointing.
Hi Stephen, thank you so much for your feedback. Our Kosi is designed to provide around 20–30 minutes of gentle warmth, but heating results can vary depending on microwave wattage, positioning, and the towel’s dampness. We’d love to help troubleshoot and see if there’s anything we can assist you with. If you're open to it, feel free to reach out to us at info@kosi.au and our team would be happy to help! <3
So great for back pain and general feeling of being given a warm hug!
Hi lovely, we’re so happy to hear that! That cosy, warm hug feeling is exactly what we hoped Kosi would bring. Thank you for sharing your experience! <3
The heating process is complicated when you are in pain and takes a lot to heat up for it then to cool down too quickly. I love the wrapping method it’s the reason a bought it but wouldn’t recommend.
Hi Francis, thank you for sharing your feedback. Kosi is designed for gentle, wearable warmth for around 20–30 minutes, but if it's cooling too quickly or feels complicated, we'd love to help troubleshoot and simplify it for you. Feel free to reach out to our team at info@kosi.au, we’re always here to help and support you.
Aesthetically please
Practical and generous dimensions
Does not stay warm for long
Materially very stretchy, I have to be gentle when putting it over my back
Hi Izzy, thank you so much for your honest review. Kosi is designed to give around 20–30 minutes of gentle, wearable heat and as for the fabric, it’s intentionally soft and flexible for comfort and we appreciate your feedback and always take notes on ways to improve.
If you’d like, feel free to reach out to us at info@kosi.au and we’d be happy to help troubleshoot your heating routine or assist further.
My husband and I purchased one each.. We both love the snug feel and fit but the heat simply/sadly does not last. I started mine at 2 mins now I’m up to 3.30 mins and still doesn’t last long at all before I need to reheat. His as well. Disappointed as it’s not an inexpensive purchase. We both have had to pull out our old wheat bags as a back up as they hold the heat heaps longer. We only bought them 2 weeks ago and we both need them regularly throughout the day with both of us with horrid back pain.
Hi Stephen, thank you so much for sharing your experience! Kosi is designed to provide around 20–30 minutes of gentle, wearable heat, but results can vary depending on your microwave’s wattage, how it’s folded, and the dampness of the towel used during heating.

If you’re open to it, please feel free to reach out to us at info@kosi.au so we can support you both further.
I love how this heatpack feels like youre getting a big snuggle. Its a shame that it doesnt stay very warm for long so when in pain with a flare up its up and down to the microwave every 15mins
Hi lovely, we’re so glad you’re loving the snuggly feel and that warm hug feeling is exactly what we hoped for. Kosi is designed to provide around 20–30 minutes of gentle warmth, but every microwave setup is a little different. If you’d like, we’d love to help troubleshoot your heating routine to get the most out of it, feel free to reach out at info@kosi.au anytime. We're always here to help!
I purchased a snuggle for my Husband for Father’s Day as he gets really sore neck and shoulders. I thought I’d spend a bit extra and try and get him a decent heat pack, this looked perfect…. However he has only used it three times as it takes forever to heat up to a temperature that is worth having on his shoulders, we’ve tried many ways and followed the instructions but it takes so many goes to try and heat it up wrapped in a damp towel and then doesn’t stay warm for very long. When you are in pain you just want something that is easy. Our old heat bags are back on rotation again while I look for something else.
I have to say I think I may Ihave wasted my money sadly.
I was unsure if I should buy this at the start but wow I’m so glad I did, it’s been such a life changer for my chronic conditions. It’s literally my emotional support heat pack now I use it every single day. I’ve tried so many heat packs and this one is so unique, the material is so soft and cozy and the smell isn’t bad at all, in fact I actually like the smell it calms me down. I love it so so much, the only thing is I wish it was a little bit longer on the back to target mid back as well but otherwise I love it. I even use it for my legs and stomach, it works everywhere!
Hi Rosa, thank you so much for your lovely feedback. We’re so glad Kosi has become your emotional support heat pack and knowing it’s helping bring comfort through your chronic conditions means everything to us. Sending you all the cosy warmth, always! <3
I got this for my teenage daughter. Last year she was diagnosed with stress fractures in her lower back. Heat packs are great pain relief for her but all the traditional ones are small and she would have to tuck them into pants or low down for them to stay in place. Kosi has been so perfect, just heat, wrap it around her back and she can get on with things. 10/10 quality too!
Hi Kacie, thank you so much for sharing this and your feedback means a lot. We’re so glad Kosi has been the perfect fit for your daughter and that it’s giving her both relief and freedom to move without the hassle, it’s exactly what we designed it for. Sending all the warmth in her way! <3
The Snuggle is so comforting – it feels amazing to wear and fits really well. I love how soothing it is and the relief it brings. The only thing I’d love to see improved is the back section over the shoulder blades being a little longer, and maybe the addition of a small hook or clasp across the collar bones to help it stay perfectly in place. Even so, it’s such a wonderful product and I really appreciate the comfort it provides to sore shoulders, neck and upper back.
Hi Brodie, we’re so glad the Snuggle is bringing you comfort and relief where you need it most and really appreciate your thoughtful suggestions about the shoulder coverage and front clasp, feedback like this helps us grow and continue improving for our community. Thank you for taking the time to share it with us! <3
The Kosi 360 is honestly like a warm hug. I love that it wraps around so comfortably and can be worn under my clothes, which means I can keep moving through my day without having to stop and sit with a heat pack. It’s been such a support during endometriosis flare-ups and in my recovery after laparoscopy – soothing, practical, and comforting all at once.. Its been a Game-Changer for Endo and Recovery from laparoscopy. I wish I had found it sooner!
Hi Brodie, thank you so much for your beautiful review, it truly means the world! We’re so glad Kosi has been a comforting support for you and hearing it’s helped you stay moving through the day makes us so happy. Sending you all the warmth your way <3
was hard to warm up first time as you needed to wrap in a damp towel so it doesn’t burn and was hard to fit in my microwave and didn’t find that it stayed very warm for long compared to a wheat pack bit disappointing
Hi Melanie, thank you for sharing your feedback and we really appreciate it. The damp towel step helps protect the fabric and allow for safer, deeper warmth, but it can definitely take some adjusting. If you’d like, we’d love to help troubleshoot your heating method to get the best results. Feel free to reach out to us at info@kosi.au and our team would be happy to help!
It is very comfortable, applies a good amount of pressure with the weight all around.
Bit of a hassle to warm up, smells a bit odd.
Hi Lauren, thank you so much for your feedback and we’re really glad to hear you're loving the comfort and gentle pressure the wrap provides. Heating can definitely be a bit fiddly depending on your microwave, and that natural flaxseed scent can take a little getting used to at first. If you’d like, we’re happy to help troubleshoot, feel free to reach out to us at info@kosi.au and we’ll guide you through it!
love the idea but in reality way too hard to heat up
Hi lovely, thank you for your feedback, we’re really glad you love the idea behind Kosi. Heating can sometimes vary depending on the microwave, so if you’re open to it, we’d love to help troubleshoot and make it easier for you. Feel free to reach out to us at info@kosi.au
anytime!
I’ve used my Kosi for three weeks now, following my first laparoscopic excision surgery last month. It is great that it is hands free and provides 360 degree heat to the stomach and back, which provides comforting relief. I believe another section of Velcro needs to be added to the Kosi to prevent the significant piling of material, caused by the Velcro catching and pulling on itself. It also catches on skin or other material which could be prevented if a corresponding section of Velcro was added to the design. The bags are quite heavy and at first was too much weight to put on my stomach immediately following the surgery (especially when the bloating from the gas was at its worst). The bag is also already very stretched and out of shape (after not even 3 weeks of use). Overall. I think it is convenient and very comforting, but lacks the quality I was expecting of a heat bag at this price point
Hi Anne, thank you so much for taking the time to share your experience, we really appreciate your thoughtful feedback. Your suggestions are genuinely helpful. We’re always looking for ways to improve, and feedback like yours helps guide that process. Also, we take product quality seriously, and your note about the Velcro and stretching is something we’ll absolutely review closely. If you haven’t already, please feel free to reach out to us at info@kosi.au so we can take a look and assist you directly. <3
I have Adenomyosis and endo also. I get to the point that I'm in so much pain I can't move.
I have tired many other heat packs they would fall off or the wheat would go to the one side and you could never find the prefect size. UNTIL NOW. KOSI, is amazing... I am to heat it up and get around slowly. And wraps around my body providing relief and comfort in one.
Thank you. 😊
Hi Pauline, thank you so much for your beautiful message, it means the world to us. We know how intense that kind of pain can be, and we’re so happy Kosi has been able to bring you real comfort and support. Sending you lots of warmth! <3
At first the kosi was good
But the more I use it the more the stuff inside seems to be disappearing maybe from
The heat of the microwave
It’s become lumpy and I am not liking it.
It’s not as much as an all over coverage as I thought it would be
Hi Denise, thank you for your feedback, we’re really sorry to hear your experience has changed over time. That’s definitely not what we want for you. We’d love to take a closer look and help figure out your concern. If you haven’t already, please feel free to reach out to us at info@kosi.au with your order details. Our team would be happy to guide you through the next steps and see how we can help. <3
I use this heat pack nearly all day everyday. I have Endometriosis, adenomyosis and PCOS and have chronic pelvic and back pain from it. This heat pack allows me to still get on with my day (having 3 kids) whilst getting some relief from my pain. I love the fact it is 360° meaning everywhere gets heated up and I don't have to decide between my pelvis or my back. The only downside is that I feel the fabric is a little thin and I worry it'll break. Otherwise I absolutely love it! Been a huge game changer for me!
Hi Jasmine, thank you so much for sharing your experience and we’re so glad Kosi has been a game changer in helping you manage pain.
As for the fabric, we’ve designed it to be soft yet durable, but if you ever have concerns or need support, our team is always here to help. Feel free to email us at info@kosi.au so we can take a look and assist you if needed. <3
Bought it for my girlfriend who suffers from endometriosis. She absolutely loves it, especially as it gives her the relief she needs when the pain becomes too much.
Hi Ash, that’s so lovely to hear, thank you for choosing Kosi for your girlfriend! We’re really glad it’s bringing her the relief she needs during those tougher moments. Sending both of you lots of warmth and love. <3
