I have been sleeping on the Beautyrest Harmony Lux™ Anchor Island - Firm SIZE: Queen for almost 2 weeks now. The first thing I noticed right away is the quality of the mattress, it's sure to hold up for many years to come. Another feature I am pleased with is the firmness level, I sleep on my back and prefer a firm mattress, so far I have gotten great support when sleeping each night. I wake up every morning well rested and ready for my day. The last feature I want to mention is how cool I stay at night when sleeping on my new mattress, this is very important to me, I can't sleep if I get too hot, or if the mattress I'm sleeping on doesn't have cooling capabilities. I am super pleased with the overall functionality, quality and firmness and support this mattress provides. I look forward to many great nights sleep for many years to come!
