I bought this for my granddaughter who just moved in to a dorm at college with a mattress that's about 2 inches thick. I asked her on a scale of 1 to 10 with 10 being the best, how would you rate it for comfort? She said it's definitely 100! She said everyone in the dorm says that she has the most comfortable bed. I hesitated to purchase this because there were so many other products that were less expensive but I've seen them and knew based on the mattress on her bed that she needed the best product available. I'm so glad now that I didn't waste money on something less expensive that I'm convinced wouldn't have delivered such excellent results.
