Erotic furniture

Erotic furniture,  represents any form of furniture that can act as an aid to sexual intercourse. Whilst almost anything can be used for this purpose, the most common form of furniture employed for sex is the bed, but couches and sofas come a close second. These are not strictly erotic furniture, as their primary use is not erotic.

Specifically designed furniture for erotic purposes can include
 * Devices for spanking and flagellation such as the Berkley Horse
 * Sex swings
 * Devices for using gravity to aid in lovemaking without the use of complicated slings. LoveRocker
 * Fisting slings
 * Liberator (sex furniture) Various types of angled foam wedges or specially designed pillows that support various sex positions.
 * Bondage equipment such as stocks and pillories
 * Smotherboxes and other queening stools.
 * the Love Chair, a curious chair made of curved tubular sleel, articulated in several ways and designed to facilitate otherwise impossible sexual acts. This device was advertised in men's magazines in the mid 1970s, and is seen in at least one of Nina Hartley's Guide to videos, but it is no longer commercially available.

See also Edward Gorey's The Curious Sofa, (1961), a neo-Victorian pseudo-porno send-up consisting of non-illustrations&mdash;there's always a potted palm or something in the way. One caption reads "That evening in the library Scylla, one of the guests who had certain anatomical peculiarities, demonstrated the 'Lithuanian Typewriter', assisted by Ronald and Rupert, two remarkably well-set-up young men from the village." The Curious Sofa of the title is approached with some misgivings by the house-party guests at the end.
