One-sided mattress
View Patent ↗A one-sided mattress construction includes a spring assembly with asymmetric spring coils. Only the bottom portion of each spring coil is attached, either to adjacent spring coils or to a bottom surface of the mattress. The top portion of each spring may have a narrowing taper that permits the top to move independent of other adjacent springs.
1. A mattress, comprising
a plurality of adjacent asymmetric pocketed spring coils being
unattached to an adjacent asymmetric spring coil along a top half of that spring coil, and
attached to a bottom portion of an adjacent spring coil such that a top portion of the spring coil and a top portion of the at least one adjacent spring coil are independently moveable with respect to one another.
2. The mattress of claim 1 , wherein
a plurality of said spring coils are attached to form a string of attached coils which are unattached to adjacent strings of coils.
3. The mattress of claim 1 , wherein
said spring coils are attached to at least one adjacent spring coil with an adhesive.
4. The mattress of claim 1 , wherein
said spring coils are attached to at least one adjacent spring coil with a hog ring.
5. The mattress of claim 1 , wherein
said spring coils have a top and a bottom interconnected by a continuous coil of wire having a convex longitudinal taper along an exterior surface thereof, the convex longitudinal taper having a radius of curvature that monotonically decreases from the bottom of the spring coil to the top of the spring coil.
6. The mattress of claim 1 , wherein
the spring coils have a top with a first width, a middle with a second width, and a bottom with a third width, the top and the bottom connected by a continuous coil of wire, the spring coil having a longitudinal taper such that the third width of the bottom is substantially equal to the second width of the middle, and the first width of the top is smaller than the second width of the middle.
7. The mattress of claim 1 , wherein
the mattress has a rigid bottom surface, and the plurality of spring coils are attached to the bottom surface of the mattress.
8. A method of manufacturing a mattress comprising:
providing a plurality of spring coils;
arranging the plurality of spring coils adjacent to one another in a manner suitable for use in a mattress core;
attaching a bottom portion of each one of the plurality of spring coils to at least one other one of the plurality of spring coils; and
enclosing the plurality of spring coils in one or more upholstery layers without attaching a top half of any one of the plurality of spring coils to any other one of the plurality of spring coils.
9. The method of claim 8 , wherein
the spring coils are asymmetric coils.
10. The method of claim 8 , wherein
a plurality of said spring coils are attached to form a string of attached coils which are unattached to adjacent strings of coils.
11. The method of claim 8 , wherein
said spring coils are attached to at least one adjacent spring coil with an adhesive.
12. The method of claim 8 , wherein
said spring coils are attached to at least one adjacent spring coil with a hog ring.
13. The method of claim 8 , wherein
the plurality of spring coils have a top and a bottom interconnected by a continuous coil of wire having a convex longitudinal taper along an exterior surface thereof, the convex longitudinal taper having a radius of curvature that monotonically decreases from the bottom of the spring coil to the top of the spring coil.
14. The method of claim 8 , wherein
the plurality of spring coils have a top with a first width, a middle with a second width, and a bottom with a third width, the top and the bottom connected by a continuous coil of wire, the spring coil having a longitudinal taper such that the third width of the bottom is substantially equal to the second width of the middle, and the first width of the top is smaller than the second width of the middle.
