This is a very sturdy base. I enssembled it myself. It looks like it will last for many years. The instructions are easy to follow and with the cover it looks more expensive than what it really is.  I gave it a 3 stars because the slots are not flat and the spacing between them is big and I think thats going to decrease the life of the mattress because it doesnt lay on a completely flat surface. This is important to me because I suffer from back pain. Now if you dont have back problems, this box would be perfect for you and the price is right
