I ordered this for my spouse who is a firefighter and has a twin bed at work. It is absolutely essential that they get good sleep, and the old topper that was at the station wasn't doing the trick. Ordered this and my spouse is sleeping so much better! It's easier for them to get back to bed after mid-night calls, they have less lower back pain, and they feel like their sleep is more restorative. Packaging was good, was easy to set up, and the noticeable difference in quality was immediate. We plan to buy one for home now too!
