As far as placing the deity in the bed is concerned, if the deity is large and heavy, it is not possible to move Him daily. It is better that a small deity, which is also worshiped, be taken to the bed. This mantra should be chanted:
agaccha sayana-sthanam priyabhih saha kesava
O Kesava, kindly come to Your bed along with Srimati Radharani. [Hari-bhakti-vilasa 11.40]
The deity should be placed in bed
