Walked in and explained to Mark that my wife had a bad back and we were in search of a firm mattress. Mark pointed immediately to a therapedic brand mattress and told us that’s the one. We tried it out and loved it but didn’t want to make an impulsive buy. We left to shop around some more. We found nothing to compare at that price and comfort level. We were back in to see Mark the next day. We bought that 1st mattress he recommended. Great shopping experience! Thanks Mark!
