Best AV Receiver for 2025

AV receivers are notoriously complex, with reams of features and confusing technical specifications. (For example, what's 4K/120Hz anyway?) Yet, what are the things that really matter when buying a new model? I'm going to sum up the most important ones right here. HDMI inputs With most TVs and set-top boxes supporting HDMI, you should buy a receiver that has as many of these HDMI input ports and outputs as possible.

Bedsure's Bamboo Cooling Sheets Are Silky Soft, Durable, and Cheap

I’ve met many supposedly “cooling” sheets in my time as a mattress and bedding tester, and I have been disappointed more often than not.
