Sex furniture can also include swings and slings that can be mounted over the door or from the ceiling.
There are also inflatable wedges and chairs for easier storage after use.
Many of these pieces also have options to add bondage cuffs or already have them. Some of the sex furniture, specifically called "Sex Toy Mounts", also has room to add vibrators or dildos.
Not all sex furniture looks kinky; many of the related products in this category are designed to blend into the normal household decor - like the Liberator Humphrey which looks like a standard pillow.
