Abstract: An innerspring mattress wherein the middle portion of the mattress has two superposedly arranged sets of springs having different degrees of firmness, a rigid member, such as a plate, being insertable therebetween to provide two additional degrees of yieldability to the mattress. By placing the firmer set of springs either upward or downward and by either inserting the rigid plate therebetween or not, four degrees of flexibility for the mattress are provided. The mattress also comprises an improved handle structure to manipulate the mattress, the handle structure being mounted in cooperative relationship with the coil springs of the mattress construction.
