simple checklist:
1: do you have private space you can set aside for it, preferably a reasonably large area that can be closed off from casual encounters.
2: how large are you? if small enough, a youth crib that is 5' long might do. There were some based on a single bed mattress made by sears some years ago, you might find one in a flea market or by a want ad. otherwise getting one made, or making one yourself if you are good with tools are about it for options.
3: if it is just you caring for you, a crib & a room to keep all your stuff in should about do it, a rocking horse is good addition along with some mats to use on the floor for rolling around.
if you have a caregiver:
1: changing table, hip hight, 5' long fitted with some simple retraints to geep you on it and hands away from interfering.
2: large rocking chair for cuddles
3: a large highchair, if you are small some made for bigger kids may work for yo. There are places to buy care aides like strollers & highchairs.
4: a playpen but in an adult size, mine uses gym mats so the 'floor' is 6'x6', the sides are like the gates for a crib and likely will need to have them made.
ThrashBear does good work & delivers his products over a wide area, google him to find him. Good luck!
PS: i wish i'd gotten a crib years ago, is the single best AB prop ever...
