This base is very well made and was easy to assemble. I bought it to replace a very high end traditional box spring ( for my new mattress). I wanted to downsize, have more room under the bed and obviously wanted a quality product that met my high standards.  This product is as great as all other reviewers before me stated.  I'd recommend this base,( any height btw )to 
anyone who needs it.  I don't know why anyone would buy a traditional box spring when we now have a better option!  I have the 18 inch with a 14 inch mattress, it feels and looks like a Princess bed! 
On a side note,  I use a dust ruffle for my bed and will need to get something to hold it in place because it slips around on the base, ( I had to pin it) But,  it is fine for now unless and until I'll have to rotate my mattress. The mattress does not slip on the base at all btw. Great product
