It's exactly as described and shown in picture. Though took me around 4-5 hours to fix it (I am not a typical DIY guy). My son loves it. I bought both of my mattress of 15cm thickness but one thing I would like to add that upper mattress can be thicker than 15cm (May be 20cm-25cm) but trundle mattress has be 15 cms or max 16 cms. Trundle is not attached with the main bed so can be totally moved away from main bed, In that case it will become 2 seperate single beds.
