I just bought the Winkbed bed in a box about three weeks ago. I researched for days on the on line reviews that can drive you crazy.
We purchased the Cal King luxury firm model and figured we have 120 days to try it or they will pick it up and refund us.
Looks kike it is not going back, it is a keeper.
