It includes a cover main body and a channel arranged around the side of the cover main body for a full circle, a channel opening is arranged on the channel, and a tightening rope is arranged in the channel. The diameter of the channel is larger than the diameter of the tightening rope, and the tightening rope extends out from the channel opening. The channel opening is provided with a first sewed support element that partially blocks the channel opening. The first sewed support element is arranged below the tightening rope, and the tightening rope is tightened to drive the cover main body to tighten. The present invention has the following advantageous effects: it is ensured that the tightening rope will not rub against the bottom of the channel when the tightening rope is tightened; the tightening rope can be fully tightened, the interior space of the furniture cover is reduced, which reduces the wind force and has good wind proof effect.
