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!

So far I haven’t really got to get a feel of it. I will say it came smelling very strongly. I’ve had it now for 3 days & it still has a smell. I let it sit out for 24 hours, with the window opened but it still has an odd scent & once I put it on my bed it’s still smelling strong. It’s kind of hard to focus on my comfort when the smell is very odd & foul but aside from that. The reviews are on point in regards to its softness.
