Ian was amazing and extremely knowledgeable. I highly recommend anyone who is looking for new mattresses to stop by and talk to Ian. I learned things I never knew about how to make the right choice on what bed to choose . With this I was able to select from a wide variety of beds that fit my comfort style and was in my budget. I’m not sure I will be back anytime soon due to how happy we are but will definitely go back when we purchase our next mattress!

Beds were more pricey than I was expecting. But the guy working was awesome. Great attitude, easy to work with. He showed me beds in my range and what was about to be their newest deal. He was able to get the price of a bed that was outta of my range into it. And because of him and everything he did I was able to get a bed I wanted that day. He made it quick and easy. Will definitely recommend

Ian took a look at the order I had with a chat person. Asked if I wanted to try something a little better, and then what I ordered. So I did. I did not like what I would have ordered and paid for! He was very helpful. And kept it under our spending limit.

Ian & Matt were very informative and personable. They were able to clarify differences in quality and features between a number of mattresses, and we then made our purchases accordingly.

Was a fast and easy purchase.. went in and was greeted by Ian who is amazing by the way very friendly and welcoming. I got 2 twin 10in mattresses for under 600 so Def a steal. He also helped me get the mattresses into my car and was very nice to my kids as well. Overall Def nice place to go and get a mattress love that they still got stores to go in and lay down and try them out before buying.
