“I purchased an extra firm King mattress from National Mattress, and it has completely transformed my sleep. For years, I woke up with lower back stiffness because most 'firm' mattresses on the market still have too much sag. This mattress provides the solid, flat, orthopedic support I actually need without feeling like concrete. The edge support is fantastic, there’s zero motion transfer, and the price was hundreds less than the big-box department stores. The delivery team was also professional and on time. If you need real support, don't hesitate—buy it here!"”

“ultra firm support core feels like a wooden box. it doesn't give or move at all. took the delivery guys almost an hour to navigate it around our stairs using ropes and straps. that thing don't bend at all. kinda strange in my opinion. probably a wooden box under a little foam. which is fine. it's what we wanted. it's firm and it is helping with back pain. ultra firm lives up to the hype. but if we ever move, then we'll have to book the same guys to get it out of here. it's nearly impossible.”

“It was not an easy decision to chose the right mattress…we faced many complications in just getting the mattress inside our room because of the narrow staircase, but Peter was cooperative and helped us return the mattress twice and also suggested us this Galaxy HD Pillow mattress which not only fit into our room but met our needs as well. I am very thankful to Peter for suggesting this and would like to give him 5 stars for his help and assistance. Thank you National Mattress for making such nice mattresses ❤️”
