Thank you for the mattress. I did same day cash once I bought. I was looking for over 3 days learning as well. I didn't want to impulse shop and i wanted collective information before i spend over 1000, I kept asking questions then got the one I felt i needed. With a good price as well. I dont know the mattress industry an I dont wake up an buy a new mattress every single day. Just once every few years when needed. So I felt I got a great deal posturepedic by sealy. ( I hope this last 10yrs) or at lest 6-7 I think most complaints people make are just a preference issue for how they sleep rather side or stomach and preference , soft vs firm or stiff or what is actually firm in their own minds compared to their old mattress. So im not over thinking it and over analyzing like others do im happy. I wish it was a little soft with hug to my body tho, laying on it without sheets in the store with plastic on top for 30sec is a way differently feeling then what i would feel every night at home. maybe it will soft as time goes. But I also RATHER not sink in my bed tho. So can not be picky all around its better than what I had

My husband and I had an excellent experience purchasing a new mattress at the Mattress Firm in Dundalk today. Patrick gave us a fair, honest education about all of our options and was very patient and knowledgeable answering all of our questions. He made us feel comfortable, didn’t rush, and made sure we had everything we needed for many nights of fantastic sleep for years to come. Super excited for our new mattress and highly recommend Patrick & this store.

I had a wonderful experience with Mattress Firm.I visited the store two weeks ago and told the sales person what I wanted. He directed me to several mattresses without pressure. I tried them out and left to give it some thought. They communicated with me by text and we decided on a day before me to come back in. S different salesperson was there but equally knowledgeable and supportive. I was given a good package for which I am very pleased

Nate was wonderful to work with. He was extremely knowledgeable and took the time to walk us through each style and brand of mattress. He allowed us time to test out each mattress and helped to guide us through our decision without pushing his opinion or own agenda. He was very accommodating and a pleasure to work with. We highly recommend meeting with Nate.
