I ordered two single 3 foot mattresses to be placed on a super king size frame. They fitted very well and are extremely comfortable. They are soft enough to be cosy and comforting, but firm enough to be supportive. ￼I am waiting for a new hip and I often have a very uncomfortable night with very little sleep. Last night I slept in this for the first time, and for the first time in a very long￼ time, I only woke up a couple of times. When I buy a bed for the spare room, I wouldn’t hesitate to buy another one of these mattresses for it. They are soft enough to be cosy and comforting, but firm enough to be supportive.
