Everything and everyone was top notch. The layout/display of the mattresses on the floor made for easy comparisons. Salesperson was helpful and did not tire of our repeated questions. Delivery and haul away of our old product when smoothly. Mike and his helper were organized and proficient in their delivery and assembly. KCMattress is a top notch outfit. I highly recommend them it was a great experience.

I can not say enough good things about my experience with the staff at the Olathe KC Mattress City store!!! From the moment I walked into the store the staff were welcoming, good listeners and went out of their way to answer all my questions and make me feel comfortable in trying out their many mattresses. Received call that my mattress arrived sooner than projected and today delivered and set up by two more very nice staff. Looking forward to a good nights sleep!!! Thank you Olathe KC Mattress City folks!!!!

Thank you Paul and Trevor! My wifey and I stumbled upon KC Mattress while desperate searching for a quality mattress. Not only did we find a quality mattress, we found a quality company, awesome staff members and a frickin coffee espresso bar! Trevor and Paul answered all of our questions and helped us choose the proper mattress and we actually had fun. You guys are great and deserve raises! We'll stop by for regular updates and coffee time!

Trevor was fantastic, and the reason we made our purchase. He was very knowledgeable and genuinely wanted to help us find the right mattress. We shopped around elsewhere, but ended up coming back to KC Mattress to work with Trevor. 10/10!

Five stars is doing a GREAT injustice for this family. ⭐️ X 1000 = BEYOND superior. Listen, I am a VERY busy mom with a career that allows minimal down time (clients are TOP priority). I’m over the moon, for the comfort I will feel, with the few hours of sleep I get. I’ve been looking for a mattress for well over a year that will meet my need, and they have FINALLY provided it. More importantly, our service was beyond exceptional. I genuinely felt like I was kicking back, enjoying life with my friends, in a very relaxing atmosphere. Far exceeded my expectations! Keep doing what you do and thank you for your service. If Forbes cared about my vote, just know you would be #1!
