I have some questions about toppers. To start, I have a fairly new firm, queen size inner spring mattress that's in like new condition. I'm a side sleeper. I find myself wanting more cush or padding for my hips and elbows. I roll around a lot at night trying to get comfortable. I'm a 6 foot tall 245 pound divorced male. I  tend to sleep hot. I've been considering memory foam toppers from Costco and others. I'm also looking into latex toppers as well. Is there some kind of guide or rule-of-thumb to follow when it comes to body weight and toppers? Is latex better than memory foam for my situation and my sleeping hot? What about thicknesses and ratings? I've read some posts about 'heavier' individuals sinking right through their toppers, which is certainly a concern in my case. Are there some internet sources I could be checking out? Every site I've visited thus far has indicated their products are the best. Any input or suggestions would be much appreciated. Thanks.
