I prefer a firm mattress and this one definitely is. I've been using it for about 2 months hoping to break it in but it is just a bit too firm and uncomfortable. I thought I would like the coils but after just a couple weeks I could already see the edge of the mattress starting to sink and would not regain its original shape even though I only sit on the edge very briefly upon waking in the morning. Rather disappointed with this mattress from a previously tried and true brand. Hopefully future mattresses will be constructed with more durability.
