I received this Beautyrest Black 2024 Line 3 Firm mattress last week. My partner and I love it so far.  The comfort in comparison with our old mattress is undeniable. The support is a little bit more on the firm side which we wanted. Making the durability and motion isolation great. The weather hasn't been too hot lately but we can't wait to try and see the temperature regulation feature too! Definitely worth the price and it was very easy to open/install. Would recommend buying!
