Right...I have my funky, fun, fairly luxury well made but lightweight stroller...a micralite toro with rider board for the dd1, dd2 is in buggy and very comfy but i want to buy a second pram for walking/ baby sleeps in house after walk while in buggy etc....my need to collect dd from playgroup at lunchtime means some days post lunch naps in cot not available for dd2 so......what's the most comfy buggy seat you can suggest?? This is my top concern for this purchase, my frivolous fun colourful part has been met by the micralite toro, it's ace! Dd2 is very big so width of seat and prob length will be good but also mainly comfort, I like air tyres....size not a prob. Are mountain buggy seats very comfy? Nipper single? Mothercare extreme three wheeler thingy? Any better suggestions please?!
