I have been through literally every sir mattress maker and style possible in the last 14 years of base camping, backpacking and mountaineering. Not sure what these people's probliem is, but I can tell you from personal experience with this mattress and pretty much all other available...this is absolutely the best. The seams are FAR stronger than the Ozark Trail, Coleman or uber expensive mont blanc ones. I have had to replace mine twice in 6 years. That's after using it approx 10-20 times per year and, yes never following the directions and folding it up for storage right. I just have never been able to get it back to the original fold. There must be some nobel physicist working in the factory to get these things in the shapoe they are shipped in. But even with bad storage, I've NEVER had an issue with this. My only fear is that this company will eventually quit making this model
