To whom it may concern, I want to thank Josh at the Moses Lake Mattress Firm store for all of his help in his abundance of knowledge of information to help me understand why my previous mattress purchase only 6 years ago was not the right choice for my needs! The sales person that I bought my Sterns & Foster mattress from 6 years ago in South Hill Puyallup, Washington did not have the knowledge that I needed to help me to make the correct decision on purchasing the correct mattress for my medical needs! The new mattress purchase that I made 6 years ago should have been a purchase that I would not have to make another this soon in my having to purchase another brand new mattress again so soon 6 years later! Meaning if I would have had the correct information to help me back then to make the right choice in a mattress that I absolutely needed to help me with my medical needs! I feel very confident in knowing that I am making the correct choice now for my medical needs in this purchase! So thank you very much Josh for all your helpful information and time! Respectfully......Linda Sumner

View on GoogleWent into store just to get some info on beds. Came out with planned purchase. Returned today and bought a new bed! Joshua was there both days and explained how the adjustable bed works. Very able to answer all questions my family and I asked. He knows his information on the beds well! Thanks Joshua for all your help.
