Peter was the absolute best and so helpful! He definitely got me the best deal I could get, provided great customer service and really made helpful suggestions based on my sleep patterns. Plus he’s hilarious!
View on Google⭐⭐⭐⭐⭐ My husband and I had a great experience at the Mattress Firm in Simi Valley. Peter was friendly, knowledgeable, and not pushy at all. We truly appreciated his honestly. He made the process easy and helped us find exactly what we needed. Highly recommend asking for Peter! Hands down the best time we had shopping for a mattress. Which we are so excited to looking forward to better sleep!!!
View on GoogleWhat a great experience! Peter B was so helpful and very knowledgeable. He helped us get a mattress for our granddaughter and found us a new mattress and adjustable base. Peter does not upsell and he takes his time to identify what you need. All reasonably priced! Shop here!!
View on GooglePeter is either a psychic or just that great his job or both. In two questions knew what I would like. Even my price range I know was probably to low. He showed me what he had available that I would like. Even the Beautyrest Black was it in my budget. Give me a pretty good option for another model Beautyrest. That was almost the same for half the price. Really trying to find a solution. That I'm keeping in the back of my mind. Thanks Peter for your help tonight.
View on GoogleI went into the Simi Valley store not exactly knowing what I wanted and Chris asked the right questions to determine what was the best option for me. Although I ended up spending more than I wanted, he gave me the most possible discounts available and I am very happy with my purchase. I appreciated that Chris was knowledgeable, very courteous and not high pressure at all.
