Getting Rid of Tiny Biting Bugs?

We had a chair on our porch that really was an indoor chair. I sat in it a few months ago, came into the house and felt all these bites and could see tiny blood spots. I immediately took a shower and that seemed to resolve the situation. I also threw out the chair that was on the porch.

Around the same time I had put a couch cushion outside to dry. It got left outside and that night it rained. I left it out to dry. When I finally brought it in, it was on the couch maybe 2 days. Then when I threw out the chair, I threw out the cushion as well since they were both out there at the same time.

I do not get constant biting. This last attack I believe was from me opening the couch and vacuuming. It stirred them up. If I leave the house the biting ceases and really only occurs if I have been sitting on my couch. I have picked them up, and they continue to bite. I can feel them crawling on my skin, face, and body. The ones I have caught look like black pepper flakes that are shiny or like a clear skin color that's kind of blobby. They do not break when I try to slice it with my fingernail.

The bites do not turn into bumps. The area becomes red or I see tiny blood spots. They are not fleas or bed bugs. I am noticing I'm getting more strawberries on my skin. Strawberries being the small pink spots on your skin that are often raised from the skin. I thought I was going insane till I found this site and saw a lot of others dealing with this. I believe they're some type of mite and bought Kleen Green in hopes that will work. More than likely I'll just throw out my couch.

Does anyone know exactly what they are or been successful with getting rid of them? I'd just like to talk to someone about this because it's driving me nuts and my husband thinks it's a big joke. My son who's not even 2 is getting bitten as well and that's the worst part.
