The mattress is great quality, it didn’t have a strong odor as mentioned in other reviews. The mattress arrived quickly and was packaged very well. It may take two to lift and open but it was simple to open and let it rise. 

I can’t say for sure how it’s affected me sleep wise as I let it rise for 72 hours and have only slept on it one night. It is comfortable to lay on and if it doesn’t benefit me sleep wise that’s on me not the mattress. I am pleased with this mattress!
