Mines 94cm - the fireguard is in two sections that you move together/apart to get the right size, then screw together. Each half is about 94cm across the front, so you cant make it shorter unless you cut the metal and do something to make the sharp edges safe.
Hi, i have one of those from Mothercare and have just measured for you. Each 'half' is 83cms wide, so if you pushed one end right inside the other you would have just over that i guess. I can't see why it wouldn't work like that unless anyone else see a problem? hth
