I ordered the twin version of this bed frame.  I absolutely love it.  Very pleased with the sturdiness of the frame and the level of support it gives the mattress.  The only reason I gave it 4 stars is because the frame is very slippery.  In order to keep the mattress from slipping around on it I had to place a non-slip pad between the mattress and the frame.  Other than that it is perfect and I highly recommend this purchase.
