We are selling a quax baby cot together with an aerosleep mattress in condition as good as new. Our daughter used it for about 14 months since she was 4 months onld but it has absolutely no impact on condition. The quality is top notch and we are selling it only because she is ready to move to a toddler bed. 
The mattress is also in great condition. 
I bought the two items at 510 euros in total and I am offering a healthy discount
