UPDATE UPDATE. Less than 24 hrs after finding out things were not handled properly through Corporate. James reached out to me directly from the Arnold location. We went up and met with him in store and I am pleased to say not only did he make things right, new Mattress will be here Friday. So if you need help with services go see James at the Arnold Mattress Firm Location. 5 Star service from James!!!!!!

Great experience. Coffee and donuts were hot and fresh. Practice nap was a little short but otherwise all was wonderful. Skip and Jerry were very knowledgeable and polite. Thumbs up to all! Oh crap!!! Wrong store. Sorry. All was great. The guys are very helpful. Kyle and Jim are an asset for the franchise.!!

James was awesome! He showed me several different options from the firmness of the mattress to the affordability of my budget. He did not pressure me or try to get me to buy a more expensive mattress. I would definitely recommend him to any one who needs a new bed.
