Back Booster 1001 Inflatable Lumbar Support Cushion

Good Shape, Poor Quality (2008-08-12) Rating: 1/5
As others have noted, this thing leaks a lot. Basically, it is single layer construction -- like the cheapo type of air mattresses for swimming pools. The outside has a kind of short velour-like texture, which is not bad. Despite the leaks, it works okay for sitting on the sofa. However, I originally purchased it for use during an air flight. I discovered that since the seats are so close now, when I used the cushion my face was too close to the seat back in front of me. I purchased this thing for a reduced price, so the low level use is okay. However, at $20 or so now, it is well overpriced for the quality. I will look for something else to support my back...

Does what it needs to do---but has a slow leak so must be reinflated every 24 hours. That's a disappointment.
Good adjustable lumbar support for travel (2008-07-02) Rating: 4/5
This product works well for travelers using rental cars or airlines. I gave it four as opposed to five stars because the adjustment process (blowing into a tube then trying it) is inherently a litte tedious. And over-inflating can be bad for your back as well.

On the other hand, it stuffs into your carry-on/briefcase with no problem and works well once adjusted. So the ability to deflate it completely is also inherent to its value.
deflates too soon (2008-01-31) Rating: 2/5
I had the same experience as Robert of Niagara. It worked well at first, but it developed a leak after a week of use in my car. It quickly became useless.

This happened twice. (Thinking that the first one I bought just had a defect, I foolishly bought a second one.)

Just a reminder, not for daily use (2008-01-27) Rating: 2/5
As it specified, it is supposed to be used occasionally, such as travel, not daily use. I tried to use it daily at my office, but it soon worn out, and deflate quickly. I have to return it.
