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.

Very Firm!

I love how firm this bed is on my back, I have scoliosis and a back fracture and feel so much firm support on my back with this bed.

Have high hopes

My back kills me on my current mattress after only a little over a year so I had high hopes the firm seals will hold

Very comfy

So far so good. Excited at how firm it feels. I always crave that style mattress and it's been going a good job since

Comfort

Love my mattress. Gave up my Queen Serta after 15 years. Smaller and still as comfortable. Even my kitty loves it!!

Relaxing

I love the mattress. It is firm but soft at the same time. This is the first mattress/box springs that I have own which so much taller than my others and I really like that.

Comfortable

This mattress was not as firm as I thought it would be. It is much more comfortable than I imagined. I was not able to lay on a display in store, which I usually like to do. To my surprise I like it very much
