The bed never lifted to full 10 inches. The highest was the middle at just under 9 inches. The edges crumbled down easily if you put weight on it (especially the corners). The middle of the bed was soft and comfortable when you lay in it but you’re stuck staying right in the middle. Any turn to either side cause you to squish down the mattress. I thought ordering a coil spring hybrid would provide the right balance but it did not. I have tried a different brand and it holds up better.
