Lumi's Core Assist

Works exactly as advertised. It’s such a unique concept and I was hoping it’d work, it helps me sit up straighter and it’s super comfortable. It fits really well under my shirts too. It has an adjustable strap which helps me tighten it. It’s easily storable too which is a plus. It takes some getting used to since I’m not used to standing up straight, but it’s doing exactly what I needed.

Does as exactly as it's described! The relief of using this band is amazing! I bought it due to a back injury and slight scoliosis curve, its been a lifesaver! 20 minutes a day and add 10 minutes every other day is how I did it and a few constant self reminders to keep myself straight and I feel great!

I've been struggling with hunchback from long hours at a desk. This brace is surprisingly effective. It feels a bit tight at first, but once you get used to it, you notice your posture is better even when you're not wearing it. Great for building good habits.

I bought it for myself and have been used it for a few days, the strength is good and protect me from over bend my back and chest. I think it is good for keep using it for a while and correct my posture.

I have found this to be a reasonably comfortable device that, indeed, feels like it holds my shoulders and back in a better position. However, although my normal t-shirt size is large, I found the large size of this posture corrector to be a little undersized, leaving me with only about one inch of the total 8 inches of velcro overlap for adjustment. I have been using it for about three weeks, now, but can't say I can visually see a difference, yet. I think it's kind of like vitamins - you rarely noticeably observe the impact you intend them to have, you simply trust that they are having that impact without you noticing. One thing I was surprised to learn was that lacking clear instructions on how to use the device, there exists very specific knowledge that guides its us, which the consumer should be aware of. I will share what I learned about this specific Luckela Posture Corrector product on a popular AI service, below. Note that the lack of this information with the product is why I have rated it four instead of five stars.Wear duration and tips- Start with short periods: Begin by wearing the corrector for only 15 to 30 minutes per day.- Increase wear gradually: Add about 20 minutes each day as your body gets used to the corrected posture.- Do not overtighten: The brace should feel snug, not painful. Your goal is a gentle correction, not restriction.- Maximum daily use: Do not wear the corrector for more than two hours per day initially, and avoid wearing it all day long. Your muscles need to build strength on their own.- Build muscle memory: After about 21 days, consistent use will help your body develop the muscle memory needed to maintain proper posture without the brace.- Combine with exercise: For the best and most permanent results, use the corrector along with posture-strengthening exercises and stretches.- Wear over or under clothes: The Luckela corrector is breathable and can be worn discreetly under or over your clothing. However, wearing it over clothes is recommended if you have sensitive skin to avoid direct contact.

It’s good for posture

I’ve dealt with back and shoulder discomfort for a couple of years, mostly from long hours at my desk and not realizing how often I was slouching. I allowed this to go before recognizing I had a problem. So I decided to give a posture corrector a try to see if it could help. It was simple to set up right out of the box and easy to adjust and the design is simple with high quality materials. You will notice it at first but after a couple of days it will blend in and become part of regular clothing items. I must say it was comfortable when I had it on and served as a great reminder to sit straight but without being heavy or restrictive when moving around.After using it the past 2 weeks, my back and shoulders feel less tense by the end of the day. I usually wear it while I’m working or doing chores around the house, and it fits under a T-shirt without standing out, which I really like. For the price, it’s been a great find. I’ve seen some expensive options out there, but this one does exactly what I need and has made a real difference in my daily comfort.All in all it was a great purchase that hopefully will prevent me from having any issues in the future

Es muy cómodo

This posture corrector has helped my husband a lot. His job requires a lot of strength and movement, and with these straps, he's able to keep his tendons in place and his back straight. My husband is very happy with this product!

Good posture vest. Easy to wear and the strength is just ok to correct my shoulder and back. I have been wearing it for two days and it feels good, I think it worth it

It’s a great product. It’s very comfortable. The only reason I didn’t give it 5 stars is because it’s a bit small. It does the job and that’s all.
