The Bed Store

It’s hard to determine if a mattress is comfortable just by lying on it for a few minutes or keeping a picture of it under your pillow. The Bed Store has rethought the mattress-shopping experience from the ground up. Its has replaced the typical showroom feel with a spa-like atmosphere that removes distractions and allows thorough tests of Serta or Tempur-Pedic mattresses to take place in peace and quiet. At its other locations, The Bed Store and its employees also foster sound sleep decisions, helping shoppers choose from a wide array of mattress features, such as memory or temperature-regulating foam tops or eco-friendly sleep surfaces with bamboo-fiber covers and soy-based foam.
