Bliss Memory Foam Mattress

I have 3 of these mattresses. I absolutely love them. One in my main bedroom, one in the guest bedroom and one in my rental! Rverone loves them. Im a all over the place sleeper. They accommodate every position extremely well!

My son loves it. The second one he has had. The other lasted for years.

I ordered a King size and they sent me a California size, it's too big, I don't want it, how can I return it, I sent a message the next day it arrived, but no one answered
