memory-foam mattresses
I'm currently in love with the idea of memory-foam mattresses.
Apparently a memory-foam mattress is more expensive than a regular mattress + a memory-foam overlay separately. This is the opposite of what one would expect from buying a bundled product (which is somewhat similar to buying in bulk) (also there are fewer fixed costs). I'd like to find out more about this kind of economic phenomenon.
