TThe Sealy Hybrid Premium Collect Firm Silver Chill is an awesome mattress. This mattress is the best of both worlds having both inner springs and foam infused with silver for the chill factor. I love a firm mattress and was worried this would not have enough support for me and also wondered if the memory foam would be too hot since I am a hot sleeper. This mattress does not disappoint. I love my new mattress! Super comfy, super chill!
