We bought our first ever cot mattress, we did a little research into this before hand and found the CuddleCo Lullaby. We originally found it on a different website but it was out of stock for months. I was so pleased when I found it available on Olivers Baby Care. We haven't yet got to the stage of babe using it yet, but I had a sneaky lay on it on the floor (not in the cot) and found it comfy and that was with my adult weight on it. The fit was great, the material is great and the value I would say in the current market is unbeatable! Great product and would recommend (this caveated with the fact I am going by experience thus far). Thank you for a great experience! I would also highly recommend Olivers Baby Care for any purchase, communication was great, delivery time great and will be looking for future products from you.
