Excellent Extra Firm Mattress With Right Amount Of Soft Cushioning On The Top – Just What I Needed! I recently purchased the open-bag model of this mattress(NM HD 10" Extra-firm Flippable High Density Foam Mattress - Queen) from clearance, and I’m truly impressed with its high quality and great comfort. The extra firmness is exactly what I was looking for — supportive and solid, plus the built-in pillow top cover adds just the right amount of cushioning on top for a comfortable sleep. One of the best features is that it is flippable, allowing it to be used on both sides. This not only extends the mattress's life but also makes it more versatile. It’s an in-house product made by National Mattress, which clearly shows in the craftsmanship and build quality. On top of all that, it comes with a 25-year warranty, which gives me peace of mind for long-term use. Overall, a fantastic value for anyone who prefers an extra firm mattress with a touch of softness — highly recommended!
