Where can I find an expert witness on mattresses?
I’m in a dispute with a mattress company and want to sue them in small claims court for fraud of warranty. Where can I find an expert witness or someone really knowledgeable about mattresses to look at it and give an opinion?

Expert witness transportation, per diem, and fee costs, even if allowed in a small claims court, would probably amount to much more than the value of the mattress. Accept the mattress deficiency as a learning experience and move on.
If an innerspring design with body depression issues, consider replacing the top comfort layer with a talalay latex topper and a wool fleece pad.

Mattress selection is really a trial and error process. The best you can do is research the various configuration options and make an "educated guess".

Go talk to the guy that makes $6 an hour selling mattresses. Those guys are always experts.
On downtown street corners.
Try calling the legal department of a competing mattress manufacturer and ask who they use.
ASK BILL!
Why? What did they do Jas?
