Mattresses, Beds, and How We Sleep

Even knowing this much, it is easy for many people to...

Microcoils

[caption id="attachment_199" align="aligncenter" width="242"] Leggett & Platt "Softouch" Microcoil[/caption] Definition Microcoils (or minicoils) are coils which are smaller than standard innerspring coils.  Innersprings are usually 6” to 8” high.  Some microcoils are 4” high, but most are much shorter, usually 1” to 2½” high. They are also narrower and made with lighter gauge wire.  Some microcoils are only ¾” tall.  At least one supplier calls the shorter ones...
