It took this old Grandma 2 hours by herself to put together.  I did have an issue w bottom trundle wood slats being too short, however Wayfair is getting me replacements as I type.
I’d say I may reinforce the bed slats with a few extra nails.  The color is slightly darker but not bad!   I got a 12 inch mattress for top and 8 for trundle.
I will be trying those furniture sliders on the trundle, only because the rug I have (wicker) has a weave.   I want to see if it will help from catching and tearing the rug.
