Watertown SD Mattress Store

The most recent addition to the Montgomery’s family is the Watertown showroom which opened in 2013. We were excited to be welcomed into another South Dakota community and to grow our team with many Watertown and surrounding area residents. At sixty thousand square feet this is our largest showroom and first Mattress 1st location. In addition to Mattress 1st it has a full Flooring and Surfaces department, Hunter Douglas Showcase and vast furniture showroom for our design team to help customers complete their home and business projects.

Most recent additions to Watertown include our Clearance Outlet and Montgomery’s market. The Clearance Outlet houses manufacturer closeouts, discontinued and floor model items brought in from all locations offered at deep discounts. The market is our mix and match room collections for one low price.
