This mattress meets every expectation. The only difference between this and the name brands is the price. We got the firm and it REALLY is. Would love to compare it to the medium. Maybe in the guest room? Regular sheets fit this 14" snug. You'd need special deep pocket sheets for the 17".It arrived within four days of purchase and we slept on it that same night. Woke up very pleased with the purchase. Unlike our old pillow top mattress this will last for many years.
