I've had this mattress and box spring for about 6 weeks and have used it everyday since it was delivered and it's a little too firm for me. So I added an egg crate topper and a pillow top mattress pad topper and that helped with the firmness. I believe this mattress is well made because the stitching is good. Also, my wife and I are larger size and it holds both of our weights well. My pets like it, they jump and roll around on it. Aside from being slightly more firm than I would like it's also pretty tall. I'm about 5'5" and it sits at my waist line. All in all it's a good mattress, but firm, a little too tall for me, but it's made well and if you prefer a firmer mattress it will work well for you.
