Due to recent back problems and a lack of good supportive furniture in my apartment, I picked this up to try and help improve my posture while working at my computer. I purchased the standard density, not the firm, and I wish I had gotten the firm. The standard foam squishes a little too easily and too much, so it didn't really feel like strong support in my office chair. If you need only a little adjustment this may be okay, but if you need good support, go for the firm density. I've moved this to use in the car and it helps there. Quality-wise I've had no issues, but unfortunately this didn't really work for my back so be aware of what firmness you need.
