I don't see where there is obvious advertising? I've checked the new posts and the businesses do exist and they advertise the cushion, I just googled the names.
I've had the Comfy Client Cushions since 2008 and they are still in excellent condition and used almost daily. The Affinity body bolster is a copy version of the Body Cushion made in USA. The Body Cushion is well made, the Affinity body bolster is made in China. I almost bought the Body Cushion, it looks an excellent product and receives good reviews. The only reason I went for the comfy client cushion was because I could interlock it for all my treatments and temporarily extend my couch for the larger clients. Plus the cushions are lovely and soft, I didn't fancy the metal near the face with the body cushion. However the USA body cushion is far better quality than the copy body bolster and if I mainly did floor work I would definitely have bought the body cushion.
They don't advertise the cushion on their websites though do they... I'm still suspicious how several new accounts have been started just to praise this cushion. For all I know you've 'googled' these places so you can use their names for fake SG accounts! I won't be buying.
Oh and as for the other one being made in China... EVERYTHING gets made in china!
