Excellent upgrade for my kids' bedrooms! We had some cheaper 3.5 year old full foam mattresses, and as my kids have grown they've started to mention how they are uncomfortable. I ordered these and they were a hit! They're a hybrid, so they're supportive, but the top definitely provides a lot of plush and comfort that they're looking for. I also love that these are tall - as my son's platform bed has a decent amount of space and this one definitely filled that in. No more pillows sneaking away from him at night!
