Cheap quality, waste of money. After only 8 months it's already making loud ceaking sounds whenever we move even slightly. My husband and I are not large people ( 125 and 180 lbs). My side is creaking as loudly as his.  I am so dissappointed. Should have kept our 10 year old box spring which was still in good shape, and not creaking, but thought I would get a new one since we purhased a new mattress. Apparently, there's no warranty, so guess this will go to the dump. Should have spent the money for a better one, lesson learned. DONT WASTE YOUR MONEY!
