It arrived!
It's huge!
And has cables that might actually be up to the task!
I'll test it out in a couple of days to make sure it works.
Then I'll open it up and check out the components.
Can't right now. Made the mistake of washing a memory foam mattress topper. It's been drying in my shop - completely clogging it up in there - for a week now. When I make bad decisions, they tend to be over the top.
Should be able to sleep on it today. Yay! My poor back.
