THE best mattress ever!!!! It's a wonderful mattress in every aspect. We love the firmness. It's excellent for our backs. We have had some lower back pain from working a lot, and this mattress makes us feel like brand new every morning. It's AMAZING!!!! It's great for back sleepers, side sleepers and stomach sleepers. We wish we bought it much sooner. I highly recommend this product to everyone. You will have the best sleep ever too. Great quality. Thank you so much!! Excellent quality.
