Well choosing a good mattress is very important to me as I have a back problem, so need something supportive, but still comfy at the same time. Now we opted for the firm, which when you sit on it in the shop you first think oh no it's too firm, but I tell you once your in bed, it's just the most amazing comfy mattress I've ever had, it like envelopes you, if your a fidget in bed, then soon you wont be, because you just get in and don't move because your so comfy! Have faith and go for it, you wo t regret it!
