I wish I can give this trundle bed zero stars but I guess I have to settle for 1 star.  
I had to get parts for this bed three times because the bed was damaged and missing pieces.  They finally had to send the entire bed to me but the slats on the headboard and the foot board do not match and we couldn't get the bed into the highest position so we couldn't use the trundle with a mattress.  This bed was so much headache and not worth the 4 months going trying to get the right parts to the bed.  Wayfair ended up giving my money back in the end with 15% off next purchase.  The people working at customer service were super nice and patient with my frustration.  Wayfair has great customer service but they really need to work on quality control on their merchandise.  I really wanted this bed to work for my 4yr old but it didn't work.
