I ordered the queen bed without the trundle; however, the center support (which the slats lay on) is off-center to accommodate the non-existing trundle.  The day bed had already been put together and didn't want to deal with returning it, because I really like the overall look. My husband is going to have to put in additional support so if someone sleeps in it the slats below the mattress won't break.  Overall, it was easy and quick to put together, and it is beautiful, but I would not recommend this product if you are going to buy the queen size bed without the trundle.
