So far, so good! Not gonna lie, everyone is right, it's just about the perfect mix of firm and soft. I sleep on my side/tummy, and it holds up, and I'm not a little person (I mean I'm chubby little women!) I really love how you don't feel your partner move, I work at 4am, and we don't feel each other coming or going. It was a touch heavy, but in all fairness, I couldn't wait for my husband (due to wanting it to poof asap). It was probably funny to watch, but alas I had the last laugh cause it did indeed poof! Umm it's shocky, I hate static electricity, like really hate it, a lot, and this is shocky! When you release the beast, cut the plastic, and you start pulling back the thick plastic mattress jail, it hurts like time little tazers. So, if your sensitive to static electricity, use a poking stick, or wait for an adult lol! But if a chubby little mexican lady can do you can too! All in all, so far thumbs, tentatively up!
