It's not the best , its advertised as medium firm and it's as hard as nails . My grandson says it's most uncomfortable,  so may need to purchase a topper at the same time . The finish on the top is nice , but underneath only had a thin layer of material  which will soon tear. Do not expect to get the mattress that wayfair have used on the picture to advertise this , as it has nowhere on the union jack logo , or label  .
