I cannot say enough about this daybed. It is quite beautiful and the quality exceeds our expectations!  It was fairly easy to assemble (less than an hour for my handy husband and teenage son). Friends have asked about what we spent for it and when I ask them to guess, they all have guessed $1000 or more!  The trundle truly has a 8" limit for the height of the mattress. You could put a 9 or 10" on the top but the 8" looks just fine. Highly recommend this product!
