I did the sleep quiz and helix dusk was recommended for my husband and I. I am a stomach sleeper and my husband is a back/side sleeper. He could literally sleep on the floor and have the best night sleep, firm is definitely what he prefers but I need a little give. So I figured this bed would be a good fit especially with the pillow top addition. I think it’s perfect for me. It’s very comfortable and I can tell it’s firm without being too firm. My husband still thinks it’s too soft but like I said he would sleep on bricks if he could. I love the height it has to it. I have a platform frame and the 14 inch height gives it a nice lifted look. I read other reviews about it giving on the sides when you sit on it and this is true. I’m 110lbs so it’s not so bad for me but my husband is closer to 200lbs and he’s mentioned the sag in it when he sits on the edge to put on his socks.
