At first I was worried because it was only 1.5 inches but let me tell you...

Pros

- very thick and sturdy for something so thin
- a true memory foam push down on it and it holds then releases your handprint like it was never there
- perfect fit for my queen-sized bed not all bed supplies fit the size they advertise
- complements my bed topper and other bed accessories
- light and easy to maneuver I’m nowhere near strong and was able to do this myself

The only con for me is I wish the green tea scent was more powerful. 
Just Perfect for me, I feel the back pain while waking up every morning but now I am fully energetic. Strongly recommended. Please throw it for 24hours before using it as per guidelines.
