Need Foam Rubber Wedge Pillow For Bedridden Person

[Dustoff]

Needs to be firm but not hard. Full-body length, about a 30-deg angle.

Perhaps a medical supply carries such things? Cannot afford an electric bed.

Thanks for any leads.

the biggest shop i know that cuts foam rubber to any shape or size and covers it in plastic is where the green arrow is

the blue arrow is the next biggest and the red arrow is a very small shop

good luck ... dave2

in a related quest has anyone sourced these high density foam rollers people used for exercise? they are pretty firm and I think they are made from beaded polyethylene foam cells that are injected into a mold.

or maybe EVA -- Ethylene vinyl acetate

Okay, so math has never been my thing. If the base of the wedge is 100cm long, how high does the back of it have to be to make a 30-degree slope down to the point?

Thanks for that, Dave2. How far from the river is the shop down Charoen Muang Rd? And the one East of the SE corner of the moat?

I will likely skip the plastic cover and go with a non-slip material (nails?) or I may find myself zipping right off the foot of the bed.

SOHCAHTOA is your friend. Tangent of 30 degrees x 100. 577mm, or 57.5cm

You are talking about a well known triangle that has the ratio of 2 - 1 - √3 (see figure)

If I understand your description, the 100 cm is on the long side of the triangle, horizontal, the vertical side has to be 50 cm and the sloping side will be 50 X 1.732 or 86.6 cm.

If the short (vertical) side is the 100 cm, then the slope will be 173.2 cm (and the long side 200 cm).

No matter what the dimensions are, there is always that fixed ration of 2 - 1 - √3, as shown.

And my experience has been that any good curtain maker usually makes cushions and should have no problem making this pillow.

Now........ where can one be made for the fellah? I doubt whoever makes it will use any of the mathematical formulas.

I know some shops in Baan Tawai have cushions made at nearby "factories". I could never remember how to get to the factories. I have been escorted to a factory by a shop owner in the past. SOOOO.... if all else fails, you could have someone go to Baan Tawai. However, as some have stated, most upholstery shops should be able to make this.

Your neighborhood curtain shop would be more convenient than a Baan Tawai factory. If they can not do it, they will know who can.

All Dustoff has to do, if the 100 cm is a firm, fixed dimension, is use my "recipe" for the other sides and give who ever he has order the pillow a crude right angle triangle with the dimensions written on it. They can take it here and there until they find someone who can do it. Of course, need to add how long.

did you read my whole post?

Good luck, Dusty. I'm out.

I'm quite sure that dave2's place @ the green arrow is where we had the baby's foam rubber mattress made which included a removable vinyl cover. Heading away from the river towards the Super Highway it's about 1/2 way??? on the right side and I believe it's on a corner.

We had it made 2 years ago and it is still as firm as it was when we first got it.

There's a place on Chang Puek Soi 4 which seems to upholster everything from car seats to large sofas and benches for bars/restaurants. Have had a couple of things rebuilt there before. Coming north from Chang Puek Gate, Soi 4 is on the left at the traffic lights by the Bus station/white elphants. Shop on the right about 50M down the soi.

There is a shop which makes custom-made mats for yoga and work-outs: as large and as thick as you wish. RE the above map, on the top inside of the canal, on Sri Poom Rd, roughly across from Wat Chiang Yuen. Good quality. Quality vinyl covering: choose your own. Great for a child or invalid, alone or to top an existing expensive mattress. Cost depends. Cheers.

Well, this thread seems to have started quite a conversation. I am honored that so many TV members are interested in assuring that I get a wedgie. This should also prove helpful for those considering doing some reupholstering.

What I am looking for may have become a bit lost in the shuffle however. My wife has visited a few shops and discovered that they are all using plastic foam, not foam that is real rubber. One shopkeeper told her that foam rubber has become very difficult to find in Chiang Mai and offered to glue 20+ layers of one-inch plastic foam together and try to carve out what I am looking for. This would be functional I suppose if I wanted to wash a very large dish but it is hardly what I am seeking.

We continue to look and the 'green arrow' place on Charoen Muang is next..

Thanks to all of you who have contributed so far!

You seem to have your calculations mixed up as the hypotenuse (slope) is always longest in a right-angled triangle - perhaps drop your square root onto the adjacent. In any case, op, see above for the correct opposite (vertical) side, which is the tangent of the opposite angle (ie - 30 degrees) by the adjacent side (100cm) - 57.7cm. If you have a vertical of 50cm, your angle would be less than 30 degrees, perhaps 26, so I guess no biggy.

Thanks for that - the numbers didn't make sense to me either but since the 30-deg was just a starting point, it didn't really matter much.

We will check with our curtain lady who did our whole house but I cannot imagine her having the equipment or stock to cut a wedge of that size. A sack filled with cotton batting is not going to work either as I cannot have lumps or bumps on the top side. The old princess and the pea thing..
