This doesn’t feel like the mattress in the showroom. I tried it out twice in the showroom for about 20 minutes each time. This is firmer and a bit lumpy. Not that comfortable. Sometimes my hips hurt when I wake up in the morning. My other bed is a Serta that’s 8/9 years old and it’s way more comfortable than this one.
