We were looking for a mattress topper because our mattress my friend was clearly too hard. She slept fitfully and had morning always slight backache. This edition has completely eliminated their complaints and did me it well. The product does not smell unpleasant and remains even after several months still dimensionally stable and does not form a weld residues. We are very satisfied!
