Designed to fit the Boori range. This Dual Purpose Pocket Spring mattress caters for the needs of both your baby and your growing child. Designed for an extended life, it has soft and gentle micro pocket springs on one side of the mattress for your baby, and firmer larger pocket springs on the other side for when your child grows. Dual Purpose mattresses are encased in some of the highest density foam in the industry. This dent-resistant orthopaedic foam ensures the mattress stays more comfortable for longer. Each is designed to give maximum comfort and correct spinal support, improving the comfort of your child and extending the life of the cot mattress. The mattress has a 3-dimensional fabric on one side which promotes air circulation and assists breathability. It also draws fluid a fluid away from baby's body for comfort and safety. The bottom of the outer cover is made from a waterproof yet vapour permeable fabric, excellent for the older child when toilet training, and which significantly reduces sweating. The inner cover is made from a non-sweat water-repellent fabric, helping your little one stay comfortable throughout the night. With the John Lewis Spring mattresses we include an extra InnercareTM cover. The inner cover makes removing and replacing the outer cover quick and simple and can be used when the outer cover is in the wash. So in the middle of the night when you and your baby want to get back to sleep after a night time accident, the inner cover provides a suitable water resistant surface if the outer cover has to be removed. Optimise baby's sleep by partnering your purchase with a mattress protector from our comprehensive range.
