RELATED APPLICATIONS
The inventor herein is also the inventor in co-pending patent application Ser. No. 08/835,184 filed Apr. 7, 1997 now U.S. Pat. No. 5,970,547 for a Modular Mattress and Innerspring as well as a continuation thereof, application Ser. No. 09/302,883 filed Apr. 30, 1999 now U.S. Pat. No. 6,055,689 and Ser.

SUMMARY OF THE INVENTION
This invention provides an improvement over prior art box springs which are unsightly and have exposed surfaces in which exposed portions of the spring assemblies and frame members can injure those handling, demonstrating and using such prior art box springs. In accordance with the present invention, a protective fabric cover of padding material is provided to cover those exposed surfaces and to also provide a nicer finished appearance. The improvement is particularly significant for modular box springs and modular mattresses wherein purchasers can themselves replace originally purchased modules which have become soiled or worn. The protective fabric padded cover is releasably secured to the box spring assembly by respective cooperative strips of hook and loop construction as explained in more detail hereinbelow.
