Easy to open but have a strong smell. I just received it now so I don't know yet the quality. I will make an update after I've tried it for few months.

Arrived very quickly, in a manageable size box. A bit tricky to open the mattress but once opened left for 48 hours we were very impressed. More on the firmer side but very pleased. Great value for £.
