This is the most miserable mattress we have ever owned. We purchased ours in August 2020 and apparently it is not broken in yet ; everyday we wake, it feels like we just crawled out of a car wreck! This mattress is NOT for side sleepers.
Getting older has provided a hot, sweaty night. The pillows were uncomfortable and we were not receiving quality sleep. Then we were introduced to TEMPUR=Adapt. With a cooling mattress and the best pillows we've ever slept on, we have slept like babies. Remarkable mattress, outstanding pillows.
This mattress started out very comfortable but quickly began sagging. Because it hasn't quite gotten to the warranty sag point, we've had to endure months of bad sleep :/ This experience has also soured us on the company.
