This was my first experience ordering mattress toppers. I was pleasantly surprised how comfortable and firm they are on my back and hips. I originally intended to put two 2 inch toppers together, but found just one is enough to be comfortable. No lingering odor from the latex after airing them out for 2-3 days before using. Slightly unwieldly to move around. I'd definitely order the fabric cover for use on them the next time.
