Why're they good? Because you're bony arse says so. Post-pub drinking/gaming/Wrestlemania sessions can lead to all sorts of back-knackering seating arrangements. But plonk a couple of these 18lb super cushions on the floor and your mates will convulse with nostalgic bean bag joy. They're made of rip-proof nylon, are waterproof and stain resistant and - ahem - offer a sneaky way of suggesting different posturings to female guests without fear of reprisal (there's 10, apparently).
