  • Perfect Thickness for a Top Bunk… Comfortable, Lightweight, and No Smell
Size: Twin Style: 6 inch
I ordered this 6 inch twin mattress for the top bunk of the twins bunkbeds after upgrading the bottom mattress. The old one was worn out, and I'm really glad I chose this replacement. Right out of the box, I was shocked at how thin it was while compressed, but within a couple of days it fully expanded to the full 6 inches. I honestly wasn't sure how comfortable a 6 inch mattress would be, but I was pleasantly surprised. It's not too firm and it's not too soft so it doesn't cause any back pain. Your body gently sinks in and feels well supported. This thickness is perfect for a top bunk. You really don't want a 10–12 inch mattress up there because it makes climbing in and out harder and leaves less headroom when sitting up. This one fits beautifully and keeps everything feeling safe and spacious. Another huge plus is how lightweight it is. At only 23 pounds, I had no trouble lifting and placing it on the top bunk by myself. The fit was spot-on. I also appreciate that this mattress is fiberglass-free and CertiPUR-US certified. There was no offgassing smell at all, which is a big deal to me, especially for kids. I've heard too many horror stories about chemical smells with mattresses, but this one felt clean and safe right away. It's designed to stay cozy in the winter and cool in the summer, which should be great year round. The mattress feels well-made, supportive, and durable, and is back by a 10 year limited warranty, which adds peace of mind. Overall, this is an excellent value for the money and a fantastic choice for bunkbeds or any situation where you need a thinner, lightweight mattress without sacrificing comfort. I'm very glad I found this one. ... show more
