I'm moving soon and have decided to get rid of my Ergomotion bed frame. I've purchase it for around $1000 3 years and still in perfect working condition.

Size: Queen (http://www.amazon.com/Ergomotion-400-Power-Foudation-Queen/dp/B00H3R4UJK) or http://www.ergomotion.com/products/series400Model: Series 400 
Works with Foam or foam core mattress only (won't work with springs)

Its available for pickup in North San Jose . You would need a truck and help to move it....its heavy.
