Hello First off apologies - the coupe in question is not a Honda, but I think I've been here long enough to get away with it. So I've recently bought a 1996 Toyota Celica 2.0GT (mid-life crisis in full swing) and excitedly put the kids booster seats in the back to go for a wee family drive on a sunny Sunday only to discover the shape of the seats make this difficult (they dip where your bum should go). A cushion under the booster seat helps but I'm not convinced how safe this is. I can't be the only one with this problem. A quick google search hasn't shed any light. Anybody know of a suitable solution?
