The quality of mattress is great , definitely recommend it.  nice and firm (the way I like it’s perfect for back), not soft of course.
Point to remember :  just my assumption , I feel a firm queen size mattress feels small, if you’re the one like me who like to change sides overnight and kind of spread out on the whole bed. Queen firm mattress feels a bit small. I am upgrading to get that extra space. Overall , loved the mattress. Buying again the same one.
