## Abstract

The present invention provides a trampoline comprising a top panel, and a main body, wherein the method that the top panel attached to the mail body is RF welding or heat sealing. The present invention also provides a trampoline wherein the top panel and the main body are formed as a single piece. The present invention further provides a method of manufacturing trampoline wherein the top panel is attached to the mail body by RF welding or heat sealing, or the top panel and the mail body are formed as a single piece.

## Claims

### Claim 1

A trampoline comprising:
a top panel with a plurality of first venting holes in a first size and a plurality of second venting holes in a second size, wherein said first size is smaller than said second size; and
a main body with a center opening;
wherein said top panel is RF welded or heat sealed to said main body, around the perimeter of said top panel and said main body, covering said center opening; and
wherein said plurality of said second venting holes is arranged along the perimeter of said top panel, and said plurality of said first venting holes is surrounded by said plurality of said second venting holes.

### Claim 2 (depends on 1)

The trampoline of claim 1, wherein said main body is in a toroidal shape, and said center opening is at a center of said toroidal shape.

### Claim 3 (depends on 1)

The trampoline of claim 1, wherein said main body is gas-filled.

### Claim 4 (depends on 1)

The trampoline of claim 1, wherein said top panel comprises a flat circular panel comprising a laminated polyvinyl chloride material.

### Claim 5 (depends on 1)

The trampoline of claim 1, wherein each of said plurality of second venting holes is oval.

### Claim 6 (depends on 1)

The trampoline of claim 1, wherein said center opening is oval.

### Claim 7 (depends on 1)

The trampoline of claim 1, wherein said plurality of second venting holes is arranged in two rows along the perimeter of said top panel.
