We purchased this bunkbed for our grandkids that are 5 and 7. My husband put it together in under 4 hours.  It seems sturdy and we were happy that none of the bed was made of particle board like the dressers we purchased.  It has been about a week and there is still a smell from the bed.  I have had the windows open and fan on. I am hopeful it goes away soon!  We purchased two 6 inch memory foam mattresses for this bed.
