A gaming chair that keeps your butt cool? I’m a fan already

Ah, gaming chairs. Expensive, often ugly, but at least usually functional – if you pick up one with good lumbar and neck support, your spine will thank you. But if you pick up this one – the Fantasylab ‘Big and Tall' – your bum will thank you too. Why? Because it's got a set of four USB-powered fans built into the seat, to keep your rump warm even during the sweatiest online games.

Why do you need this? That's the neat part: you don't! Nobody does, in fact, and we're not even sure this product is real; the Amazon listing is packed with errors and the photos of the butt fans are quite clearly edited. But this is a strangely captivating offer nonetheless, leaving me with no end of questions – does it really work? Is the chair good in general? Does it really feature ‘explosion-proof' springs as per the product description?
