An important feature of an upholstered piece of furniture is the underlying construction. This Drop In Coil unit is of superior built construction in many of the upholstered items we offer. And, you can tell simply by sitting down. Many sofas today use less expensive sinuous wire spring construction.
The Drop In Coil unit pictured to the right is 'dropped' and secured into the frame and each row of coils is supported by a cross beam which runs from front to back inside the frame. Therefore, when sitting there is 'push back' on the springs which greatly reduces and helps prevent the coiled springs from sagging and this allows for long term structural integrity.
