[This review was collected as part of a promotion.] I was asked by Influencer to try this product in return for my honest and unbiased opinion Seale's Patterson II posturepedics plus spring ultra firm has to be the most comfortable mattress I have ever been able to lay my body on. Just having to have emergency hamstring reattachment surgery to where I was laid up in bed for almost 6 weeks I was so afraid that I wouldn't be comfortable and not be able to get any rest to heal. That couldn't have been further from the truth. This mattress is firm and holds my body. I don't "sink in" like foam mattresses. It has just enough give in the padding on the very top so that you know you're not laying on " a board". I can only be comfortable being on firm mattresses and this is extremely helpful to my back and to my recovery for my hamstring. I wouldn't give this mattress up if God himself asked me for it. This mattress is that good and it's beautiful!.. Lalu6060_9924. Thu Sep 04 2025
