Do they work well? What brands do you like?

I use a basic lumbar support sometimes. I guess if it helped immensely I'd use it all the time.

I've found a tightly rolled towel works about as well as the fancier stuff and is a whole lot cheaper.

Ohio, Who do you drive for? Did they spec a long haul tractor without adjustable seats?

Backsmart has about four different styles you can choose from. Every back and seat will be different so try one out before you buy if you can get your truck near a store.

I have a small pillow I use, when needed. They are inexpensive and works well.

The lumbar support I bought from Walmart was $9.99

Ask yourself if you have a back problem or if its just the seat thats f-ed up and the lumbar support thats built in doesnt work.... My wife working 4 a chiropractor, I must tell you she has a lot of drivers as regular clients incl. myself. Every driver needs low-back decompression just from the amount of sitting compounded by the pounding of vibrations :x
