Perfect! ZINUS 9 Inch Metal Smart Box Spring with Quick Assembly
I am not sure why some folks think this is hard to put together! Assembly is so simple... I recommend at least a 12 pack before you begin! The instructions include a very detailed diagram of the included parts and it is a very simple process of elimination...Quality - extremely well made and if you are so inclined, this metal box spring will definitely stand up to some serious humping and pumping!The cover was very easy to put on and the entire setup took me about 15 minutes.Highly recommend!
