Great, Well constructed, firm mattress. To be transparent, if I slept directly on this, it would be to firm for me. However, it is perfect for a base for a 3" Talalay Latex topper, which makes this the perfect mattress. I purchased this mattress with this use in mind, so it wasn't a case of the mattress being to hard. The mattress was exactly what I wanted: a high quality firm mattress to put my topper on. If you like the premium hotel brand mattresses, this mattress with topper duplicates the feel for a fraction of the price. Don't get Dunlop Latex. It sleeps too hot. A 3" topper with a firmness of 24-28 ILD (medium firmness) is just about right.
