Bests & Worsts Reviews from Amazon

These are very comfortable mattresses at a very good price. However, there is one big (small) problem. The twin size mattress is nowhere near twin size. A twin mattress should be 75" long. These mattresses are roughly 69" inches long. This means that on a metal frame there is going to be a large gap at the foot, or a space where the pillow is going to slip between the mattress and the headboard. On a wooden frame with slats (bunk bed) the mattress won't be long enough to stay on the end slats and will fall through. I fixed this on a bunk bed by putting in extra slats. However, there's not much that can be done on a metal frame. At first, I thought that Amazon had sent us a Twin XL frame by mistake because I had never heard of a mattress coming up this short. I guess, if you're the mattress manufacturer and can make your mattresses almost 8% smaller that they should be you can reap significant savings in materials over time. So, is this a big deal? It really depends, but people should know that you're getting something less than a twin mattress. Note: I went back to the bunk bed where I had to put in an extra slat (because the end of the mattress wasn't long enough to make the end slat and not fall through) and measured again in March of 2015. The mattresses are both 70" long. They were purchased and unwrapped in August of 2013. I'm guessing that they've expanded as much as they ever will.
