Laying it out was quick, and once it settled, the bed instantly felt gentler on the shoulders and hips. The padding feels thick without being bulky, and it molds just enough so that you feel supported without sinking. The airflow is surprisingly good. Even after lying still for long periods, the surface never turns warm or clammy. That was important since the mattress underneath didn’t have much ventilation.

Super comfortable

Color: Green Bamboo(2300gsm), Size: Queen

this mattress topper completely saved my bed. It is super thick and soft, but still gives enough support so you don’t feel totally stuck. The cooling cover actually works pretty well and doesn't trap heat like other memory foam I’ve tried in the past. It was also really easy to put on and the deep pockets keep it from sliding around at night. Very happy with it!
