I ordered the natural twist cot bed mattress and two mattress protectors from Little Green Sheep after having spent hours researching good quality mattresses online. These seemed to get 5 star reviews everywhere I looked. Not long ago my husband and I bought a new organic mattress for our bed, and naturally we wanted the same quality for our little one. No chemicals, no 'plasticy meterials', an ethical approach, fairtrade, that is all very important to us and we are happy to spend the extra penny for our piece of conscience. So glad that there are still companies out there that appreciate the wealth of nature and make products from its resources. As our baby hasn't arrived yet (5 weeks to go), we cannot share much of our own experience with the mattress yet, but delivery was certainly fast (2 days) and the product is well packed. It looks and feels great, fits the Mamas and Papas 400 bed well and will surely make us happy in the years to come.
