I  just love this secretary!  It came in  in four easy to put together pieces, and I was able to assemble it by myself.  (At 78, that is saying something!)  It is a lovely addition to my bedroom
where I can look out upon my small balcony as I tap my laptop.
The wooden shelf is supported by two hidden pull out pieces that provide strength from underneath.  I didn't notice them when I was putting it together, and only found them by accident.  Such a clever addition!  I can place my laptop on it as well as my enormous makeup mirror,  (When you get to be my age applying makeup needs lots of illumination.)
Really happy with this purchase.
