Most people with an interest in the BDSM lifestyle will have used a variety of furniture and implements, or at least seen the same items in person or online. Quite often one will see artist renderings, fetish artwork and so on, which is fantastic to look at, but not necessarily functional or comfortable to use in real life.
For anyone not familiar with Queeing chairs, I have designed mine so they are at the correct height to avoid any neck strain. I know some people design theirs to use a head sling to support the submissives head, but I simply altered the height of the chair to render that unnecessary. I’ve never had complaints about my versions and no one has ever had neck strain that has used one of them.
In the sample photos included in my profile, my site and my other *uncensored* adult blog, you can see that my husband is quite flat on the floor, and is using a small throw pillow for his comfort, not to elevate his head. The height of my "womanly parts" in relation to his mouth is correct, and/or some of my designs have an elevated head/back support to line up my "business" with his tongue.
And lastly, I've made quite a few where she can be sitting facing forward, or backwards to provide "full service" or enjoy whatever based on ones preferances. :)
