I was in the process of mattress shopping and had visited Mancini's Sleepworld, Costco, and Sleep Train and my last stop was Mattress Discounters on El Camino Real in Menlo Park. By far, that was my worst sales experience. There was one sales person in an empty shop, who was absolutely not interested in selling. Instead of focusing on selling me a mattress, he was more interested in making personal comments and was extremely rude.
Pros: Good selection
Cons: Poor customer service
