Fabulous item. The cool blue egg profile memory foam topper is luxurious and ultra cosy. Adjusting to body temperature this lovely mattress was the perfect addition for my son's sofa bed mattress. Having a poorly son who was on bed rest, it was comforting knowing that he had a fabulous comfortable sleep for the first time in ages. Don't know how they can provide such a quality item at such a great price. It looks very simple but excellent technology. The additional zipped protective cover was lovely and soft to touch. Highly recommended. Thankyou Mattress Guru.
