Mattress topper came rolled up in a vacuum sealed bag as pictured.  Once you cut along the end of the plastic the topper immediately starts to puff up.  There is a potent green tea smell at first but it quickly goes away (once bedding was on I didn't smell anything).  I thought the packaging was great and made it easy to put on the bed before unrolling and opening plastic.  Once you cut away the plastic, it's easily pulled away and leaves the topper in place to puff up into its shape.
The feel is medium plush, your body sinks slightly taking pressure off joints.  I felt like I could fall asleep immediately!   Once I got up, topper went back into position right away.  I love it already and I'm well pleased with this purchase.
