This was my first mattress purchase ever (my parents bought my last bed). I was extremely nervous about buying a mattress online, but when I read the reviews for the Lucid mattress, I figured it would be worth it. I was right! It showed up at my front door 2 days after I made the purchase and after I opened it, I slept on it the same night! I’ve seen some reviews saying if you’re a side sleeper that this mattress isn’t for you, but I sleep on my sides and my stomach, and it’s the perfect firmness for both! On top of this, the mattress I had before was only memory foam and did not have cooling technology so I spent many nights waking up multiple times due to being way too hot. I haven’t had a problem being too hot or waking up multiple times with this mattress! Plus, I paired the mattress with a new cooling pillow — HEAVEN. I highly recommend this mattress!
