Don't Upgrade Your Mattress...
...in April. This middle-of-spring month doesn't have any major holidays, and mattress retailers love to hold sales around days that most people have off from work or school, like Presidents' Day, Memorial Day, the Fourth of July and Labor Day. Plus, in May, manufacturers tend to mark down old models to clear them out and make room for the new ones coming in, so if you buy in April, you'll be too early to score a deal.
