A good time to purchase a mattress is near a holiday such as Labor Day. The month of May is also a good time because mattresses are usually discounted in showrooms.
Many mattress companies have big Labor Day sales and run similar sales around other holidays such as President's Day and Memorial Day.
Mattress manufacturers normally release new models in May, so sellers reduce their prices to clear the old stock. Reviews for the new models come out in the second quarter of the year, so it’s possible to put into consideration the experts' reviews, the new technologies and features in the new models before making a purchase.
