Abstract

A spring mattress with two overlapping springs. With a support layer used for encapsulating Spring downstairs Where the internal area of the support layer will be a number of lower coils aligned They are placed in rows along the width or length of the spring mattress. By the coil spring on the lower layer has the characteristics Is a continuous coil spring caused by the fastening of the spring all over the back And at the top of the support layer will It is the support layer used to wrap the upper layer of spring. Where the internal area of the support layer is coiled A number of top springs are aligned in a row, along the width or length of the mattress, the upper coils are circular, open-ended. In which the body of the upper coiled springs Was wrapped in a cloth bag

Claims (3)

1. Spring mattresses with two layers of springs stacked together consist of a layer of support material used to wrap the lower spring. Inside the support material layer, there are a number of lower spring coils arranged close together in rows along the width or length of the spring mattress. The lower spring coils are continuous spring coils formed by interlacing the springs throughout the back in a vertical manner, which creates a quadrilateral shape with sharp corners colliding. The unique characteristic is that on top of the support material layer, there is a layer of support material used to wrap the upper spring. Inside the support material layer, there are a number of upper spring coils arranged close together in rows along the width or length of the spring mattress. The upper spring coils are round and open-ended, with the top and bottom being circles with smaller diameters than the middle of the upper spring coil. The ends of both the upper and lower spring coils are open-ended, and the body of the upper spring coil is wrapped in a cloth bag. 2. A spring mattress having two layers of springs arranged as per claim 1, wherein the lower spring coil is also of a circular shape with open ends, wherein the top and bottom are of a circular shape having a smaller diameter than the center of the body of the lower spring coil, wherein the ends of the upper and lower spring coils are open ends, wherein the body of the lower spring coil is wrapped in a cloth. 3. . A spring mattress with two layers of springs arranged in a row, according to claim 2, wherein the lower and upper spring coils are arranged in pairs of spring coils. 1. A spring mattress with two layers of springs arranged in a row, inside the layer of support material, is a number of lower spring coils arranged close together in rows along the width or length of the spring mattress, wherein the lower spring coils are continuous spring coils formed by interlacing the springs throughout the back in a vertical manner by interlacing the springs at the midsection, creating a quadrilateral shape with sharp corners meeting, with the specific characteristics being that on the top layer of support material is a layer of support material used to wrap the upper spring, wherein on the top layer of support material is a number of upper spring coils arranged close together in rows along the width or length of the spring mattress, wherein the upper spring coils are circular and open-ended, wherein the top and bottom are circular in shape with a smaller diameter than the midsection of the upper spring coils. Where the ends of the upper and lower coil springs are open ends, the body of the upper coil spring is wrapped in a cloth bag (picture). Picture 1
