I have a queen size platform bed frame and organic mattress for sale. The frame is from Scandinavian designs and looks very sleek and minimalistic. It is quite easy to assemble and disassemble too.
It comes with a 6” organic cotton mattress ( queen size) . I originally purchased the mattress from a website but am moving now so have to sell it. You can check it out at:http://www.ahappyplanet.com/store/mattresses/organic_mattress_ltx_fut.html
The asking price is $ 350 for both the frame and the mattress or $ 200 Bed Frame and $190 for the mattress if bought separately. Photos attached. Thanks.
