Definitely helps but not perfect
I use this in my car. (I still don't know why they don't make the seats in cars with good lumbar support). Although the support from this device lessens over time, it's still better than having nothing, and when I'm in a car without it - I miss it. I have had no problems with it slipping around, it stays in place.

Simple but does the job
Six weeks into my new desk job I started having significant lower back pain and thought it might have been due to my chair. I looked at the Obusforme cushions but ended up buying this because of the positive reviews and the low price. I've been using it every day for two weeks, and so far I love it. My back feels much better. I would definitely repurchase when this one wears out.

great support for auto seat
Have used this lumbar support for over a month and I am really impressed with the comfort. Prior to use, I would get a leg pain on long trips and an occaisional left arm tingle. Glad to say this product fixed my back issue, apparently due to poor posture. I am using it in an older BMW, which does not have a lumbar support.

Back Relief LITE
Few chairs or car seats giv me god lmbar support but if they do it gets hot and uncomfortableon the long haul. I saw this item used by a close friend who drives across several central states frequently. She said it makes all the diffence in the world for low back pain. The store she found it in was out! I searched the internet and found it here...saw the price was reasonable and soon had one in the house. I immediately appreciated the sound construction and it utility in the car, on the desk chair and even the wooden kitchen table chairs. yet to try it in the car for any duration..as my wife put on the kitchen chair as she uses it at every meal without fail. I will wrestle it away from here for my 10 hour drive to Alabama this month. I am sur it will give great support...and keep my low back cool with sapce for air to circulate behind it!

GREAT WHILE PREGNANT!!
I got this and instantly loved it. I don't have good posture so when i first got it I was using it wrong, so I didn't think it worked. But the guy i bought it from showed me the right way. When I sat down I kept pushing it down to where the very bottom of it was at the bottom of my spine. He pulled it up to where the curve was at the curve of my back..I thought duh, should have known. I used it all the way through my pregnancy, and it helped WONDERFULLY. You can also sleep on it if you like and it will hold your spine in alignment. I think its great for any chair, even in the car, but my favorite is when you go camping to use it on those cloth fold out chairs. The frame of it is really durable to, you could stand on it and it wouldn't bend, so you don't have to worry about it getting bent out of shape and not working anymore. I loved it so much I bought 2, one for me and my husband, cause mine is almost always in use...Definately worth the little bit of money it costs (EVERY PENNY).
