Mattress Topper Comprising Pocketed Spring Assembly With At Least One Cushioning Layer
A topper for use with a bedding or seating product, such as a mattress, comprises a casing surrounding a pocketed spring assembly and at least one cushioning layer. The topper has a skirt which may fit around the mattress. The skirt may have a drawstring or an elastic band which helps keep the removable topper on top of the bedding or seating product. The height of the springs in the pocketed spring assembly is typically less than the height of the bedding or seating product.

This invention relates generally to bedding or seating products and, more particularly, to a mattress topper or pad for use in on a finished mattress.
Traditionally, toppers for mattresses have consisted of relatively thin members which may be removed from the mattress for a variety of purposes. U.S. Pat. No. 6,009,579 discloses a topper for a feather bed. U.S. Pat. No. 6,922,862 discloses a topper designed to be placed on top of a conventional mattress.
One drawback of known toppers for use with conventional mattresses is that the toppers are not durable enough and may have to be replaced frequently.
In order to achieve greater durability in a topper adapted to be removed from a bedding or seating product, such as a mattress, it would be desirable to include a pocketed spring assembly into the topper. Therefore, making a topper having a pocketed spring assembly incorporated therein, the topper being sold separately from a mattress, would be desirable.
SUMMARY OF THE INVENTIONThis invention provides a mattress pad or topper which may be sold separately from a finished bedding or seating product, such as a mattress. The present invention is not intended to be limited for use with any particular bedding or seating product. For example, the mattress topper of the present invention may be used with a mattress having an innerspring core or a foam core or any combination thereof.
According to one aspect of the present invention, a mattress topper may be used with any mattress. The mattress topper comprises a bucket or casing comprising a bottom and sides. A pocketed spring assembly is located inside the bucket. At least one cushioning layer may be located above the pocketed spring assembly. The mattress topper further comprises a quilted top layer and a skirt adapted to fit around a mattress. The bucket, skirt and quilted top layer are sewn together. In some instances, inner edges of the bucket, skirt and quilted top layer may be taped together before being sewn together.
The skirt of the mattress topper may have an elastic band or draw string sewn therein to better secure the mattress topper around the mattress.
One or more of the cushioning layers may be polyurethane or latex or memory foam or any other type of foam. One or more of the cushioning layers may alternatively or collectively be a layer of fiber batt or down for insulation purposes. Another type of cushioning layer may be a gel layer.
In some versions of the mattress topper, cushioning materials are located only above the pocketed spring assembly. However, in other versions of the mattress topper, cushioning or insulating materials may be located above and below the pocketed spring assembly.
According to another aspect of the present invention, a mattress may be used in combination with a mattress topper. The mattress topper may be removed from the mattress without disturbing the mattress. The mattress topper may comprise a casing surrounding a pocketed spring assembly; at least one cushioning layer and a quilted top layer. The mattress topper may further comprise a skirt sized or adapted to fit around or surround the mattress. The skirt may have an elastic band or drawstring at the bottom of the skirt. The cushioning layer may include one or more layers of foam and/or fiber. The cushioning layer(s) may cover one or opposed surfaces of the pocketed spring assembly. The casing, skirt and quilted top layer may be sewn together.
Although several types of mattress topper have been described herein, any of the mattress toppers shown or described herein may be used in any bedding or seating product, including a mattress. For example, the topper may be used in a seat cushion, such as a car seat.
