Abstract
The featherbed includes upper and lower fabric layers, with the upper layer being longer than the lower layer. Lines of stitching connect the upper layer to the lower layer at spaced lateral lines along the length of the featherbed, thereby defining successive abutting lateral half-tubules, which are filled such that the upper layer extends away from the lower layer in a curved configuration, defining a plurality of half-tubules, generally in the shape of half-ellipses, with the fill density being greater, approximately 21% than that of a similar-sized conventional featherbed.
Claims26
A featherbed, comprising:
- an upper featherbed fabric layer and a lower featherbed fabric layer, wherein the upper fabric layer is longer than the lower fabric layer;
- lines of stitching connecting the upper fabric layer to the lower fabric layer at spaced lateral lines along the length of the featherbed, the lines of stitching extending in a lateral dimension of the featherbed, wherein the ends of the upper layer are substantially coincident with the ends of the lower layer, and wherein the dimension of the upper layer is greater than the dimension of the lower layer between each line of stitching, thereby defining successive half-tubules with half-tubule volumes along the length of the featherbed;
- and
- filling provided in the half-tubule volumes, such that the upper layer extends away from the lower layer in an arcuate configuration for each half-tubule, with the lower layer being flat for each half-tubule.
A featherbed, comprising:
- an upper fabric layer and a lower fabric layer, wherein the upper layer is wider than the lower layer;
- lines of stitching connecting the upper layer to the lower layer along longitudinal lines spaced across the width of the featherbed, the lines of stitching extending in a longitudinal dimension of the featherbed, wherein the longitudinal edges of the upper layer are substantially coincident with the corresponding longitudinal edges of the lower layer, and wherein the dimension of the upper layer is greater than the dimension of the lower layer between each line of stitching, thereby defining successive abutting longitudinal half-tubules, with half-tubule volumes, across the width of the featherbed;
- and
- filling in the half-tubule volumes, such that the upper layer extends away from the lower layer in an arcuate configuration for each half-tubule, with the lower layer being substantially flat.
