BrownmedIMAK Ergo Back Cushion - Lumbar Support Pillow for Office Chair & Car - Chair & Seat Cushion Support for Back Pain & Posture - Back Support for Car & Office Chair with Strap

Bought this one for my husband after he tried to steal mine. We use them on the sofa since we both need a bit more support for our lower backs. I haven't used it on an office-style chair but I can only imagine it would work well. The elastic to hold it to the chairs is really flimsy but otherwise it's great quality. I've had mine for about a year now and it hasn't flattened or gotten out of shape at all.

My son got it as a gift for his mom. She likes it a lot, but it is getting softer already after just a month of heavy use. She sits at her desk for 10 hrs a day with few brakes, but its great for the price, and my son was proud to figure it out and buy it with his own money for her. Good purchase

This is a nice back cushion, but it is not quite supportive enough - also it is holds in the heat so in the summer can make you a bit sweaty. It is better than trying to use a regular or travel pillow for back support, but the elastic strap really holds nothing and needs to be ditched totally. Not a total waste of money but not quite as good as it appears either. Ditch the elastic band and make it out of memory foam and it would be quite a bit better!

I purchased this as a replacement for the first one that got a little worn out for my husband. He has some back issues and this has always helped him while he is in the car. I asked him how he likes it and would he recommend it and he said absolutely...it works for him.

My mother was forced to drive a long distance and has bad back problems especially after sitting for a while. I got this for her luckily with 2 day prime shipping and she was able to use it for her 13 hour drive and said it helped out tremendously. If she liked it that much I figured it deserved a review from me. 5 out of 5 stars

I love this back cushion. I've had it for some time now and work at home on the computer. I can truly say that I could not work for hours without this support. I have been fortunate to not have back issues as some people do who work on computers a lot, and I attribute it to this back cushion. Great buy for the money!

The Imak Back Cushion was great for short term use but due to it's softness, it easily compacts when using it for hours of driving. It looses it's value over hours of driving. I would not recommend this item for long term use for the above reasons. If this product was firmer it would probably do what I expected it to do.

i have buck seat whish it was a little wider so it wouldn't slide as much as it doesbut it is on the better side
