Adam Clarke on Ezekiel 23:41

And satest upon a stately bed - Hast raised a stately altar to thy idols; probably alluding to that which Ahaz ordered to be made, after the similitude of that which he saw at Damascus. The bed here is in allusion to the sofas on which the ancients were accustomed to recline at their meals; or to the couches on which they place Asiatic brides, with incense pots and sweetmeats on a table before them.
