I was originally going to buy a second hand one but when reviewing I found a few threads where people had bought second hand and coudn't remove the smell of smoke from the foam rubber! eeeew! So I got mine new.... bubby was 12 weeks when we put her in it and she loooooves it!
thanks for that tip, my postal delivery person smokes and it drives me bonkers, good advice as ya never really know if they are a smoker hey
