This mattress is very comfortable and fits the bed perfectly. Its depth adds to the comfort but extra deep fitted sheets are easily available.

2nd time purchased this mattress went for firmer this time. A low divan is needed as the mattress is 37cms deep and can make getting on it difficult if mobility problems. But very happy with it very comfortable and supportive. Delivery people were very helpfull

Only based on a few weeks use. All Round comfort. Did struggle to find perfect size mattress protector and if good quality but got sorted no problem eventually. This has no impact on the mattress. Hoping the comfort continues I’ve always had silent night mattress and think I would never try anything else. Not to sure on the firmness medium. Soft ect but ours is perfect for us. I always choose a deep mattress and this has so far not disappointed. Slept very comfortable
