well, the topic about the reduced capacity made me think of it:

boxes named coffins, to hlep hold the dead modies, they will be heavier, like less then 20% the corpse, and will have 20% wight reduce (for what in it). it might not be the best, though, for exploiting it, and it needs dm checking, though mathamtically it works :)

Few concerns:

Surely a coffin would be even more cumbersome to carry.

What stops people from storing regular stuff in it and getting the weight reduction? It makes the suggestion basically "Let's have magic bags for sale", no?

thats why we make it heavy. if it wights 20% of a corpse, it will be rediculous to carry lets say, 5 of them?

also, there is the RP of it, im doubt players will put the armor they wear in a coffin. though, i was afreid it is exploitable, lock this topic, then.

I certainly would never buy nor carry a coffin around, no matter what type of distorted character I have.

there coffins?
