I am super happy with this purchase! I purchased a bed with slats that did not require a box spring for my mattress. However, I did not like how low to the ground it sat - so I purchased this metal box spring. It came in a box and it was not too heavy. It  was really easy to put together. It fits perfectly on the queen size frame I had and the mattress sits perfectly on top of it. I am 100 satisfied with this piece!!
