Mattress Protectors: Protecting Your Mattress and Yourself

Protecting Your Mattress and Yourself So you are buying or have just bought a new mattress. The sales person at the store, customer service rep on the phone, or the website selling the mattress recommends buying a mattress protector, too. "Why," you ask, "do I need a mattress protector?"

What’s New in Box Springs?

What's New in Box Springs? For many of us, the box spring is a Ho-Hum item. We buy a mattress, and a box spring is included. When the new mattress is delivered and set up, the box spring is placed on the rolling steel frame, which is adjusted for fit. Then the new mattress is placed on the new box spring. We think we know what a box spring is, so we just take it for granted. The truth is, that plain old box spring under our bed might not be as old a design as we think. It may be something...

Nanocoils: The smallest mattress coils so far

Nanocoils: The smallest mattress coils so far It used to be that the shortest mattress coils were the 4" Bonnell coils in a sofabed mattress. The reason they were so short, when most coils were 7 or 8 inches high, was so the mattress could be folded to fit inside the sofa under the seat cushions. With the introduction of pocket coils, the trend was for innerspring coils, at least the wrapped coils, to become taller, up to 9 or 10 inches. This allowed greater conformabiity and more...

Beyond Wood Slats: Winged Slats

Beyond Wood Slats: Winged Slats Wood slatted foundations, more commonly known as European wood slats, were developed in 1956 by Karl Thomas and his son Wilfried Thomas for better support of mattresses. Just as James Marshall invented pocket coils for his wife, Karl Thomas developed the slatted frame for his.
