  • Life-Changer for Posture Improvement!
Size: Large (Pack of 1)
Effective Posture Improvement: This posture corrector works wonders. It firmly pulls my shoulders back where they belong, effectively relieving the discomfort I used to experience. It has significantly helped me with my slouching and humpback issues. Impressive Back Support: The double cross design and the support plates in the back strip provide outstanding support from all angles. This helps to gently disperse tension, promoting alignment and stability without causing any harm to my back. Ultimate Comfort: This posture corrector is made with a breathable and comfortable material. The wide straps diffuse pressure points and don't dig into my underarms. The added underarm soft pads are a great touch, and I can easily adjust them to my most comfortable position to reduce any friction. It's comfortable, effective, and easy to use. If you're struggling with posture issues like I was, I highly recommend giving this product a try. ... show more

  • Effective Posture Corrector
Size: Large (Pack of 1)
The Mercase Posture Corrector for Men and Women has proven to be an effective tool in improving posture, earning a solid four-star rating. This back brace offers the support needed to address posture issues and promote better alignment. The design of this posture corrector is ergonomic, providing a comfortable fit that can be easily adjusted to suit individual preferences. The breathable material ensures adequate airflow, preventing discomfort or sweating during extended wear. I appreciate the versatility of this posture corrector, as it can be worn discreetly under clothing, allowing for use throughout the day. The adjustable straps provide a customizable level of support, catering to various body sizes and shapes. Since using the Mercase Posture Corrector, I have noticed a significant improvement in my posture. It gently reminds me to maintain proper alignment and reduces slouching or hunching. With consistent use, I have experienced decreased neck and back strain, leading to overall better posture and reduced discomfort. While the Mercase Posture Corrector has its merits, it is important to note that wearing it for extended periods can cause mild discomfort, especially during the initial adjustment phase. It is advisable to gradually increase the wearing time to allow the body to adapt. ... show more

  • Helpful for Posture, Just Not Ideal for Long Wear
Size: Large (Pack of 1)
I really like the idea of this posture vest — it definitely helps me stay more aware of my posture, especially while sitting at my desk or doing light tasks. It provides decent support and is easy to put on and adjust. That said, it can get a bit uncomfortable if worn for longer periods, as the straps start to dig in a little. I think it’s great for short daily use, and it’s made well overall. With a few comfort improvements, this could easily be a 5-star product! ... show more

  • Works well, size up!
Size: Medium (Pack of 1)
This brace is very sturdy and well made. It has metal supports inside the back section, adjustable in two different areas for waist size and shoulders. It is intended to be worn over clothing as stated in the directions. There are two nice padded sliders on each shoulder strap for comfort. I chose this style as the straps and everything was wider and didn’t look like it would dig into the flesh. Happy with my choice! Definitely size up! I am 105lb & petite and ordered the medium as it was the smallest available and it is a perfect snug fit was able to size it down a bit too. The mesh in the back is quite Bunchie so you definitely wouldn’t want to wear it under a jacket and have a bulge. I guess it’s good for working from home or to wear it in the mornings and evenings to keep your posture in check, I personally wouldn’t wear it to the office. ... show more

  • I’ve been wearing it wrong…
Size: X-Large (Pack of 1)
I bought this at the end of last year. I used it a few times and it just wasn’t comfortable. The shoulders were too big and rubbed against my underarm. Well, today i randomly saw a video for one of these and now realize I have been wearing it incorrectly. You close the wide strap first, then adjust the smaller straps til they pull your shoulders back to the proper position. Duh! So I’m going to try it in the morning and see if it’s more comfortable and helpful. <fingers cross> that it makes a difference. ... show more

  • Fantastic Support, No Breathability
Size: Large (Pack of 1)
In my opinion, the most important things you need to know about this brace are: + I've bought it twice (lost one in a move) because it's just that good. I shop around for everything, but not this. This brace works. It offers full back support and does a great job of sort of redistributing your body's weight by looping around your shoulders and having the attachment points for those shoulder straps be your waist. + I used this for long periods and very regularly; the velcro never stopped working, even requiring much less frequent cleaning (in a 4-pet home no less) than what I've grown used to with other velcro things. + The metal bars that rest against your back go all the way from the base of your neck to your hips; they don't prohibit movement unnecessarily, do a great job of stopping you from moving in harmful ways, and do not ever bend out of shape! + The material is stretchy, doesn't look bulky or awful, and the belt area now has little gripping strips so that it doesn't ride up! - My only real complaint is about the supposed "breathability;" it has NONE. Good for them for thinking to have this be made from mesh for the most part. The problem with this? It's only mesh on the BACK! As in the outside, the part that doesn't touch your skin! It doesn't need to be breathable there! It's all open! The part that rests against your back? It's a stifling solid material, the same that's used to make the velcro stick. They just continued that velcro material onto the part that presses against your back. This brace would be a hundred times better if the mesh was against your back and not just for show on the outside. ... show more
