For those of you who actually have sex, Gadget Universe has the Lovers Cushion for around $40. From their product page:

The Lover’s Cushion was created to enhance lovemaking by improving the angles and depth of penetration, and it really works! The Lover’s Cushion has an innovative ergonomic construction which increases muscle comfort during sex, allowing for protection of the tailbone and hip. As an added bonus, the Lover’s Cushion was designed by gynecologists in Europe to help couples engage in unique sex positions to increase the likelihood of insemination.

I wonder if this thing would work with the Repliee Q1? (Watch for exclusive Gadgetizer coverage in 4-6 weeks)
