## Abstract

A corner arrangement for an article of furniture includes, but is not limited to, a first core having a first end and a second core having a second end. The second core is adjacent to, and substantially transverse to, the first core such that the first end and the second end form a corner. The corner arrangement further includes a first skin extending and adhered along an outer surface of the first core and a second skin extending and adhered along an outer surface of the second core. The second skin further extends and is adhered around an outside portion of the corner and along either a portion of the outer surface of the first core or a portion of the first skin. The first skin and the second skin cooperate to affix the second core to the first core without any mechanical fasteners.

## Claims

### Claim 1

A method for making an article of furniture, the method comprising:
setting up a fixture in a manner that includes a first corner, wherein the fixture comprises a plurality of cores, and wherein setting up the fixture comprises arranging the plurality of cores in a manner corresponding to a desired shape of the article of furniture;
sealing all seams between adjacent cores of the plurality of cores;
positioning a first skin and a second skin in the fixture such that, at the first corner, the second skin one of overlaps and underlaps the first skin;
positioning a first core and a second core in the fixture such that the first core and the second core form a second corner free of any mechanical fasteners, such that the second corner is aligned with the first corner, and such that the second skin wraps around the second corner;
compressing the fixture, the first skin, the second skin, the first core, and the second core;
curing an adherent between the first skin, the second skin, the first core and the second core;
removing an assembly of the first core, the second core, the first skin, and the second skin from the fixture.

### Claim 2 (depends on 1)

The method of claim 1, wherein sealing all seams between the plurality of cores comprises applying silicon to a seam between each core of the plurality of cores.

### Claim 3 (depends on 1)

The method of claim 1, wherein compressing the fixture, the first skin, the second skin, the first core, and the second core comprises placing the fixture, the first skin, the second skin, the first core, and the second core in a vacuum bag and evacuating the vacuum bag.

### Claim 4 (depends on 1)

The method of claim 1, further comprising the step of applying an adhesive where the first core and the second core come together.

### Claim 5 (depends on 1)

The method of claim 1, further comprising the step of positioning a first film adhesive sheet between the first skin and the first core and positioning a second film adhesive sheet between the second skin and the second core, and wherein the first skin and the second skin each comprise a layer of prepreg.
