Mountain Buggy Terrain Double ATP

I have twins, and I was given an old model of the Mountain Buggy Terrain. The seats are 'hammock' style, so they are far too soft for new born babies, as they offer no support. So I bought their double carry cot (£188 Jan 07) to fit on and use as a flat pram - it has been brilliant! The mountain buggy frame is 74cm wide, which has gone through every door I needed to - doctor's surgeries, my front door, pharmacist doors, and the babies have been all snug inside. I'm glad I had the babies lying very flat, as many pushchairs claim to do this - but don't! And the babies face me. The only difficulty I have now is they are 8 months old, have grown out of the pram and I need something else as robust, narrow and with seats able to lie down reasonably flat. I might have to buy a new Mountain Buggy Urban (with more supportive seats) after all...

I can't really comment too much on the price, as I only had to pay out for the carry cot, but that has been worth it, and I've used it for 8 months.
