I was very impressed with the quality of workmanship of the Proflex 1650 Economy Elastic Back Support. I would highly recommend this product. One reviewer commented that the suspenders are hard to adjust, but I found out that once you have it adjusted it works nicely you can open the belt while sitting and Velcro it back up when your working and it will not fall off your body. The only thing I had a hard time with is there was no sizing chart on the Amazon webpage so here it is... Hope it helps!

None of the companies who make these back supports seem to have ever tried their products on real people to get the sizing right. I don't see any size guidelines in the listing and the size chart offered in another review is pretty far off, from my experience. I have a waist size that varies from 42 to 46 depending on how active I am. Because the stretchy side wings are too long on the XL, it's really too big to give me strong back support. I just ordered the same thing in a size Large, which I expect to be pretty tight when my waist is at 44 inches -- but it needs to be tight to provide good back support. This brand is very well made but it's useless if it doesn't fit right. I could probably have used the XL if they had simply made the side panel adjusters a bit shorter. They were definitely too long to give any meaningful adjustability -- so you have to be within a few inches of the size it's made for or you will need a different size! As I said, this back support is very well-made but, size-wise, this company has not planned or designed very thoughtfully.

I have a 38" waist so your one size fits all average back support just barely fits, always on the verge of popping right off. From my experience XL is the same as getting a one-size. No difference whatsoever. So I thought a 2XL should do the trick. Turns out its WAY TOO BIG! At least from this company. Maybe would start at about 44" on up.

It does work because the stiffness in the waist band logically conforms the back to a more upright posture. The only downside is that it gets very uncomfortable after having a big meal so you have to let that sucker out. Sometimes it may be hard to breathe.

Medium size fits a size 29 waist to roughly a size 36 waist. Keeps back upright, and does its job quite well.

Size: Medium Verified Purchase
To be clear, this ProFlex 1650 Back Support Belt is actually an abdominal support...which can be of help for people with back problems, because if you have weak stomach muscles your chances of having back problems are MUCH greater. I've had thoracic and lumbar problems for years, and know the importance of strong abdominal muscles. Anyway, my husband wanted me to get this belt, thinking it was a back brace, which it is not. It does not significantly prevent you from bending at the waist. That being said, I'm giving the product a 4 star rating, as it seems to do well what it was designed to do: help support your stomach muscles. It's comfortable, adjustable, and seems to be good quality. I wore it several times this Fall while blocking and stacking firewood, and had no spine issues, so it might have helped, I just don't know for sure. (My back issues come and go.) I'm also 5'8" and weigh 135 lbs; results might differ for a big guy with more...uh...mass. Overall, I'm OK with the belt. Oh, and for my body size, the Medium is plenty big, just f.y.i. A size Small would probably fit, also. Also, I'd like to mention: THIS IS NOT A MAGICAL DEVICE! ***TAKE CARE OF YOUR BACK!*** DON'T TRY TO LIFT MORE THAN YOU CAN HANDLE! IT ONLY TAKES ONE LIFTING MISTAKE AND YOU ARE FOREVER SORRY!

Now, while I'm actually using this product for something completely different to back support for lifting heavy objects, I am impressed with the quality and value for money of this product. For under 12 dollars, you are getting a really well made, and solidly put together Back Support item. I purchased two of these, one was 10 dollars more than this, and out of the two, I way prefer the simplicity of this. Really well manufactured. What am I using this for, you wonder? Actually, using this in a spa for clients with large bellies. It's a long story....but the point is that had I bought a spa item just like this instead, it would have cost me around 4 times the price.

As a server, I carry heavy trays around for 8 hours a day. I also have to bus tables that come in all heights. Bending over and standing back up with heavy trays and maneuvering around the dining room with them really used to put a strain on my back, so I bought one of these.

I haven't had a problem since and know that when I get older, I will thank myself for taking care of my back now.
