Perfect!

This would be a great mattress for Goldilocks. It’s not too firm, not too soft… It’s just right. Love it.

Harbor Creek Firm Mattress

We just purchased this mattress (1/2026). It’s lightweight but firm and comfortable. I’m giving it three out of five stars because we just purchased it.

Best Sleep Ever

My Dorian is so supportive! He caresses me is all the right places. It's difficult to leave him in the morning. All day I think about when I will return. My dreams are more vivid with my new Dorian Serta Classic!
