They may, play in said coils and no more, and will therehowever, be formed in spiral coils, as shown upon afford an unyielding support for the in Figs. 3 and gt, to form elastic strands which 75 2 5 mattress under every part thereof, so as to reshall be stretched to extend transversely to sist its undue depression or straining either the length of the coils of the mattress.

I claim as my invention- 1. The combination, in a mattress, with a suitable supporting-frame, of the independent Woven-Wire fabrics stretched upon said frame one above the other, with the length of the coils in the one disposed at right angles to the coils in the other, substantially in the manner and for the purpose herein set forth.
