Very firm. Very good.

Very firm mattress which is exactly what I needed. Very glad I found this mattress after trying a few others that weren't firm enough. I personally find it very comfortable as it provides the support I need, Im sure it wouldn't be suitable for a lot of people but if you, like me, need a supportive mattress for your back then this is great. Ive put a pillow top matress topper onto it to provide a little plushness without losing the support. A really good mattress at a very reasonable price, very fast delivery from mattress online
