Q. Can one get undressed or have marital relations in a room were seforim or English Torah magazine articles are kept in a closed night-table drawer?
A. Horav Shlomo Miller’s Shlit’a opinion is that the seforim or magazines that contain proper Torah articles should be covered even when inside a closed drawer.
If the night-table or night-stand are large and the drawer is more than four tefachim by four tefachim (about 40 cm. square), and the unit is also ten tefachim high (80 – 100 cm.) the Rov maintains that the seforim inside do not have to be doubly covered, since they are already in a separate domain. However, most night tables lack that height, therefore the seforim and divrei kedusha inside require an additional cover.
