Good comfy mattress but the sides are very soft so you feel as if you are sliding off the edge of the mattress when you are sitting on it. A bit disconcerting and you feel as if you are floating on top of the springs it gives a bit of a wobble feel to it.  Though having said that my daughter loves the mattress and says it’s great for sleeping on. So no complaints from her. Good quality well made. Has been given the seal of approval from the cats they love to sleep on her bed now so must be good.
