Not firm.
Color: White, Size: Queen
This mattress topper is not firm. So it doesn’t really fluff up to 3 inches. More like inches. But when you lay on it ,it’s like so soft and comfortable. It makes you feel so cozy. I plan on ordering a second one for more cushion.

Life changing!!
Color: White, Size: Queen
I slept like I've never slept before in several years! I'm diabetic and run hot and cold all night! The mattress topper is truly a game changer! I have a mattress with 4 inch memory foam. I usually sleep about 2-3 hours and then awake 2-3 hours! Last night I didn't sweat or get hot! I'm not one to waste money when I'm already comfortable! This topper is life changing! It's quality is outstanding! And a value is priceless if you sleep and don't keep waking up! It fits my queen bed perfectly. No odor! I love my topper and never knew it would be a game changer!
