This box spring is a great buy! I received quickly & it was easy to assemble- about 30 minutes because I did it myself. Its probably much faster with two people! The box spring is made of all wood and has a nice sleeve that goes over it. I have a panel bed in my guest room that has only a mattress on it and I needed it to sit a little higher so I used this instead of a regular sized box spring and it worked perfectly.  I highly recommend this product!
