We got the cocoon accessory for our phil&teds inline buggy and it was so useful during the first few months with our baby girl...keeping her lying flat and wrapped up safely in her cosy cocoon. It was quick and easy to install, with an adjustable top which made it really versatile whatever the weather. But my favourite feature is its portability, with sturdy handles that make it easy to carry your baby from the buggy into your home and vice versa, with the cocoon doubling up as a portable moses basket when we were out and about (or just didn't want to wake her up from a nap). The only reason I didn't give it five stars was the lack of a soft lining inside the cocoon, which I think would be a great addition...but I wouldn't let that put you off buying it as it's easy enough to add your own blankets or a sheep skin rug at the bottom for extra comfort if needed.
