Our bean bag was great, until three years down the line when it was getting saggy and we wanted to refill it. The zip pull was tucked up under about 5cms of fabric, and we couldn't work it loose at all. We had to cut the fabric to access the pull, and found it was actually detached from the top of the zip, which had no stop tabs in place to retain it. It also looked like there was another zip underneath the first. When I contacted customer services they were dismissive to the point of rudeness. So check your refill zip when you receive your bag, as they won't want to know by the time you want to refill.
