It is often generally thought by many consumers that box springs do not wear out as quickly as mattresses, and therefore do not need to be replaced every time the mattress is. While the box spring is not used in direct contact with the sleeper, it does still suffer wear and tear with age and the movements of bed activities. Still, box springs were once thought to last years longer than their mattress mates. However, there are a few very important reasons that it is a good idea to replace the box spring every time the mattress is replaced. Bed sets are usually warranted by the manufacturers, as opposed to the retailers. Many retailers do offer additional warranties, but it is the manufacturer warranty that is most important as the manufacturer warranty is often the one that replaces the mattress in event of construction or materials defects. Retailer warranties are usually more like expanded return policies-- a common one is sleep on it for 90 days in the plastic wrap and return it if it's not comfortable (conditions do apply). Maintaining the manufacturer warranty is one reason to purchase a matching box spring with every new mattress. Very often, if the mattress is not used in a set with its intended box spring, the manufacturer warranty is void. One reason that many manufacturer warranties insist upon replacing old box springs with a the box spring intended for use in a given bed set is weight and construction. Many of the newer mattresses feature latex and memory foam. Even most innerspring beds have "comfort" layers made of memory foam. The use of memory foam padding adds a significant amount of weight to modern mattresses. Older box springs that predate common foam padded bed tops are often not sturdy enough to handle the extra weight, especially with a couple of adults added to the mix. Newer box springs are often designed using steel rods and construction structures that make them better able to hold up under new mattress weights. Also, box springs that are part of sets are often designed to work with its own specific mattress. It is important that the box spring and mattress work together in terms of fire protection as well. Because governments have regulated the level of fire protection that bed sets must have, but have not regulated how that goal is achieved, materials and fire retardation methods vary from each manufacturer to the next. Some bed makers use certain fire restricting fabrics and fiber contents that cause the beds to smolder instead of burn. Others use sprays that reduce the rate of burning while raising the ignition temperature. Having a matching set ensures that both parts work in tandem to protect the sleeper from fire danger. Working in tandem is what bed sets are all about. Duvet sets come with matching pillow shams; mattress sets have matching box springs. Together, using sets in tandem help ensure adequate stability and support for the mattress so that it will last longer, and provides additional fire safety. This is why manufacturer warranties usually specify that the warranties are for sets, not separate pieces.
