For a fairly dense stuffing the following calculation is used
For a cylinder 17cm diameter, 35cm height you would need 250g:

Volume=8171.28cm^3

Mass=250g

Density=0.03059496186644g/cm^3


  • Example to fill a cushion 30cm length, 15cm wide and 5cm heigh

30*15*5=2250cm^3

M=D*V

M=0.0306*2250

M=68.85g


If you are having trouble working it out just message the rough dimensions an I will work it out for you!


Kapok is a type of tropical tree that is native to Central and South America, Africa, and Asia. The tree is known for its large, cotton-like seeds, which are used to make a variety of products. Kapok fibers are silky, light, and fluffy, they are often used as a filling material for cushions, pillows, and mattresses.

The fibers are also used to make insulation, packing materials, and as a substitute for down in outdoor clothing and sleeping bags. Kapok fibers are hypoallergenic and naturally flame-resistant. They are also naturally water-resistant and buoyant, which makes them suitable for use in life jackets, flotation devices, and other water-related equipment.

Kapok fibers can also be used to make yarn and fabrics for clothing, bags, and other textiles. Kapok oil is also extracted from the seeds and used for various purposes, such as in cosmetics, as a lubricant, and as a source of biofuel.

The Kapok tree is considered as a sustainable resource, it can grow in poor soil conditions and does not require irrigation, fertilization or pesticides to grow. It is also a fast-growing tree and can be harvested every year.
