I thought the sales person was honest and sociable. Very good qualities in a young man. Tyler worked diligently to get a product that met our needs
View on GoogleManager was nice and explained the difference between mattresses and the thickness and why it mattered. Seemed to care about whether my daughter would have a good mattress and would sleep well. And really hooked me up with a good deal to help me get a better mattress.
View on GoogleMattress Firm is AWESOME!! Stephen Ankarlo in Brentwood, MO sold me a bed a few months ago which ended up hurting my back. I called him and he exchanged it for.another bed, no questions asked. He is both knowledgeable and caring. So glad I sent to him rather than going online to buy a mattress.

View on GoogleWe walked in to a store to kill time but also to look at what we wanted in the future. The gentleman was so nice and it ended up being so affordable we went ahead and bought what we needed. He was knowledgeable in each product and took the time to listen to what we needed/wanted.
