How Much Do You Have To Weigh To Break A Tanning Bed?

It's not possible to give a definitive answer.  Because the weight limit will be determined by the bed manufacturer; there will be guide-line info about this in the technical manual that came with the bed.

So the owners of the tanning salon should be able to look it up.  If a weighty person is too proud to ask then I suppose they could chance it.   It's either that or just lose the pride and ask.

Typical weight limits for tanning beds I can find for sale on the Internet are suggesting about 260-300 lbs.  Some go up to 400 lbs.  If I owned a tanning salon I imagine that I would get a good quality one, though, that could take the biggest people possible.  So the limits in a professional salon may well usually be more towards 400 lbs than 250 lbs.

Better yet, I'd ask if they have a "tanning booth" -- instead of a lie-down bed.  That would accommodate most super-size people.

Or a 100 pound person who flips in a bed puts too much pressure on a certain spot...acrylic breaks.

I weigh 310 and it has never been a problem, I own my own bed
