Rated 5 out of 5 by from Above and Beyond Service My wife, son and I stopped in to look at and purchase two mattresses and two box springs. First we arrived about 715PM, not realizing the store closed at 8PM. However, our service representative Paul took his time to show us the benefits of various mattresses we could consider. We also had to arrange to have these delivered to our new home in another four days. Paul made sure we were satisfied and stayed past 8PM to set up the delivery. When we found our new queen box spring would not fit, Paul quickly arranged to replace with a twin pair. We were very pleased and would recommend Paul and this Mattress Firm location to anyone.

Rated 5 out of 5 by from Excellent Service from Start to Finish! Paul at the King of Prussia location was great. He helped me find what I was looking for quickly and efficiently, did not try to push me to spend more money than I wanted to, and made the ordering process easy. Delivery was on time and without any issues, and I would absolutely go back to this store again.

Rated 5 out of 5 by from Great service! Recently got very nice Stearns and Foster River Place Luxury Plush Mattress. This store used to be Sleepy's and now it is called Mattress Firm. Paul C. helped us. We liked available mattress selection and how Paul explained what is the difference between mattress firmness as well as different technologies, like spring, hybrid, and memory foam (Tempur-Pedic type). We also had a chance to spend some time trying different mattress in a no stress environment. Later Paul personally helped us to process payment and schedule mattress delivery. Very nice service! Here is one episode that in my view is a good example of great service. Our mattress delivery window was about two hours and delivery truck did not arrive within promised time. So I called the store just to find out what happened. Paul personally took care of it by tracking our delivery and found out that delivery truck got some issues and was running a little late. Delivery personnel arrived within half an hour after my call. They did a nice job bringing new mattress in and taking an old one out. If you are looking to buy a new mattress I would recommend this store.
