where can i find a really cute, contemporary wooden daybed for under $500?

my parents are getting me a new bed and i like daybeds; but i like very contemporary furniture, but not metal. The ones i really like are from pbteen but are super expensive for my family. i love their chelsea smart platform bed and was wondering if anyone knew where i could get something like it for a lot less. my mother is very against ikea but any help would be appreciated.

craigslist, ebay, search up online
