Mattress shopping!

Me and my wife have been long term mattress shopping. Been putting it off for too long. I would rather buy car parts!
We bought some Purple pillows to try them out before buying a mattress. It's crazy how heavy the pillows are! I can't sleep while being hot, I rarely ever use a blanket and keep it at 70 in the house. The Purple pillows stay cold! I love it. My wife sleeps with a hoodie, sweat pants, two blankets, etc. Seems miserable. She isn't a fan of the Purple pillow.
