Mattress Firm - South Salt Lake

The gentleman we worked with (can't remember his name) was very knowledgeable and really listened regarding my specific back issues and the type of mattress we needed.  He didn't try to steer us toward the more expensive mattresses (although we ended up getting one anyway).  He was very patient with us as we tried out several different mattresses in the store.  He was well-versed in the actual mechanics of the different mattresses and all of their materials, so we felt like we were making an informed decision.
They delivered and set up our bed with the box springs the NEXT DAY, for free!  They also take away old mattresses for you, but we had already moved our old mattress to the guest bedroom.  Overall, we were very pleased with Mattress Firm and recommend them to others.
