You need two because one is always in the laundry to remove pee, poop and food. Your best bet is to hang the hammock out to dry; in fact they do not fit or last long in home dryers.
Hammocks are available through non-profit cottage industry catalogs that sell products from cooperatives in Central and South America. One excellent source, used by many in the Huntington's disease community is: Pueblo-to-People, ask for a buyer to special order these hammocks, because the buyers know which ladies at which cooperatives are still working, as the hammocks are no longer a regular item. Their telephone number is 800-842-5220.
One place to try on the web is Hammocks by RADA which has hammocks from Central America and Mexico. Try the double or the matrimonial size.
If you know of any other sources, especially for Europe, please : Email me and let me know so that I can update this page.
A bed can be placed on the floor if the concern is that the person is continually falling out of bed. This can only work if the patient is able to get up safely from this low level. Two or mare twin or standard mattresses can be placed next to each other. A standard king size fitted sheet will help hold two twin mattresses together.
A low platform bed, as used in Scandinavian countries is easier to get into and out of and is generally firmer than the usual mattresses in North American. The lower height makes it less likely that a person could hurt themselves if they would fall out of bed.
Try to remove loose throw rugs that are easily tripped over around the bed. If you have smooth floor surfaces around the bed, wood, tile, etc., a throw rug with a rubber backing can help to prevent slipping as can slipper socks with rubber dots on the sole.
There are additional items that can be used to modify existing regular and hospital beds. With the help of an upholsterer, firm foam padding can be fastened to plywood battens, covered with vinyl and fastened to the inside of the bed rails on a hospital bed. This can help keep a patient from injuring themselves from striking the bed rails. However, the result is also a bed that is 4-6" narrower.
