This gel mattress topper is exactly what I was looking for! I really wanted to purchase a new mattress, but I wasn’t looking to invest the money yet. I knew I wanted some sort of mattress pad or topper to extend the life of my current mattress. I really liked that this one offered the option to stay cool and ventilated especially since it’s not only myself in bed, but also my boyfriend and dog. There’s a lot of body heat already so I wanted to ensure this wasn’t going give off more heat. It feels like you melt into the mattress. It’s super comfortable! Feels like a brand new mattress! It stays cool also! It’s amazing!! Super easy to take out of the box and unfold. Not too much of a smell either. I unfolded it, left it on the floor of our guest room and opened the windows. I left it in there overnight but never smelt an odor. I would recommend this to everyone!!
