I have been sleeping on this mattress for about two weeks and I am very satisfied so far. I would say that medium is an accurate description - it is the best of both worlds with firmness and plushness. I personally change sleeping positions pretty frequently and I would say it is more ideal for back and stomach sleeping than it is for side sleeping. It is still fine when sleeping on my side but I find that you need a more plush mattress to sleep on your side to really let your shoulder “sink in”, especially if you have shoulder issues like myself. Overall, I am pleased with this product and I was also satisfied with the delivery. It came early and was in great shape. Another successful Wayfair purchase!
