Hi there! I recently purchased the king size Sleep Science Bamboo Firm mattress from Costco, and after two weeks of sleeping on it, I can confidently say it’s been a game-changer. The support and comfort are spot on, and it really delivers on its promise of firmness without feeling like you’re sleeping on a rock. I read somewhere that if you get a firm mattress and if it’s too firm for you, you can always get a mattress topper. What’s funny is that my dog seems equally obsessed with my mattress. He usually sleeps on my bed but often moves to the floor at night when he gets too hot. Ever since I got this new mattress, though, he’s been staying on the bed all night… so clearly, it’s doing a great job keeping us cool! FYI- I spent months researching mattresses, reading reviews, and even testing out a few options in stores before finally settling on the Sleep Science Bamboo Firm. Here’s why it stood out for me: 1. Affordability – It’s hard to beat the price for the quality you get. 150.00 discount so roughly $700 including taxes/shipping (don’t remember exact price) 2. Firmness – It provides excellent support, perfect for stomach and side sleepers like me. 3. Cooling Features – The bamboo-infused memory foam actually works! Both my dog and I tend to overheat, and this mattress has made a noticeable difference. 4. Return Policy – Costco’s return policy gave me peace of mind in case it didn’t work out. I was certain on getting a Casper but changed my mind Answer from Maleficent_Brick6506 on reddit.com
