I bought this memory foam mattress topper after reading a zillion reviews of various ones available on multiple sites. Our well lived mattress is causing a bit of body aches especially in the hips when sleeping on our sides and it needed a little help. The first night sleeping on it was fabulous, I didn't even turn over to my side and I felt very comfy and cozy all night. I just did my second night on it and I still have no complaints. I also haven't felt that it has made me any warmer than usual at night. My partner who is much larger than I shared that he felt like he sinks into it a lot but didn't seem to have any issues falling asleep and snoring beside me. I say its worth a try if your looking for some cushion when you sleep. I may even get one for my guest room mattress.
