A leather sling is a seat that hangs from the ceiling, meant to bear the weight of a person up to approximately 250 lbs.. It is not difficult to hang a sling, but to do it properly, the process takes some planning, time and a choice location from which to hang it.
Find two secure, horizontal beams in your home that are at least 2-inches by 6-inches.
Determine where to place your fixing points. Measure the height of the sling base (the wider end of the sling should be positioned at hip height); length and width of the sling at its base; the height of the ceiling or fixing point. If your ceiling is 8 feet and your hip height is 3 feet, the distance between the ceiling and the sling base is 5 feet (60 inches). Assume sling seat dimensions of 35-inches by 14-inches. For every inch between the sling base and ceiling, move the fixing points by one-quarter to one-half the number of inches outward from each sling corner. Therefore, the fixing points will move out 15 inches to 30 inches on all sides. Place the four fixing points in a rectangle measuring between 50 inches by 29 inches to 65 inches by 44 inches (sling dimensions plus the difference between ceiling and sling base).
Measure the proper length of chain. Multiply the difference between the ceiling and sling base (5 feet) by 1.5. Therefore, you will need four lengths of chain 7.5 feet long. Ask the hardware store for chain of this length, they will cut it for you.
Drill four holes into the beams. Line up an eyebolt horizontally into the beam. On a 2-inch by 6-inch beam, they should be centered. Otherwise, make sure they are at least 2 inches from the bottom of the beam. Place a 2-inch fender washer on the "eye" side of the beam. Screw the eyebolt in place. Place another washer on the nut side. Screw a nut on the back. Repeat this step for the other three eyebolts.
Clip carabiners onto the fixing points. Clip the chain onto the carabiners. Lock the carabiners shut. Clip the sling base to the chain.
