Soap&Glory's "Sit Tight" - smoother thighs just by sitting down?

Spotted this product while prowling through Boots recently, and after failing to guess the purpose via the jokey name (usually easy enough with this puntastic brand) I was curious as to what those cheeky Soap&Glory types were up to this time. Hmm... toning body lotion? So why "Sit Tight"...?

Ah: "Works just by sitting down!" proclaimed the product display. "Yeah right!" proclaimed my cynical brain.

I've now got a copy of the press release and it seems that the product does indeed start working when you sit down.

Waggishly named active ingredients "Pressocapsular-Firm-System" (caffeine-loaded) "Detoxyboost" (encourages good circulation) and "PuffDrain 82" (lymph movement) are activated by heat and pressure, and promote toning and smoothing effects in the lower body tissues.

"The friction/heat generated by the user during the act of sitting acts as a release mechanism to trigger increased movement of the product to the lower body areas most
affected by fatty tissue build-up." say S&G.

Sit Tight also contains the usual industry-standard one squillion botanical extracts, including in this case eucalyptus, rosemary, ylang, blood orange, amyris, petitgrain, geranium, palmarosa, rose, sandalwood, lemongrass and lime oils.

Normally I'd remain sceptical, but experience has taught me that more often than not, Soap&Glory's products are pretty effective.

The stated release date is tomorrow (1 May) but I've seen it on shelf already in the last fortnight. It costs £14. Has anyone got up out of their seat and bought this? How has it been for you?
