Not worth it, absolute garbage, a waste of money

Ami B 12/5/2025

I ordered a firm mattress and it feels more plush, and now less than a year after purchase, it lost all support around the edges, when I'm on the bed I can feel some of the innersprings, mattress definitely showing some indentation in certain areas. Feels like cheap materials, was good and supporting for the first 3 months and it's all downhill since. Disappointed and frustrated, never buying a Serta mattress ever again.

Serta Blue Lagoon plush pillow top

Terrence B 12/2/2025

These hybrid mattresses are all too firm. The plush pillow top makes it feel a little less firm but my hips and back hurt from the overly firm mattress. I assume hybrid mattresses are the rage for the bed manufactures because they are cheaper to make and lighter than standard old school mattresses so cheaper to ship.

Denise H 11/28/2025

I have been sleeping on the floor on a 6" mattress with 3 eggshell foams added to it and still not comfortable. I've done this for over 10 years. My husband passed away and now I have my bedroom back with a new mattress. I have an extra firm, and it is great.

Sinking

Edward M 10/25/2025

The mattress, which I've only had less than 6 months, has a depression that has not recovered. It is right where my hips are. I am normal weight, (185 lbs), and there's no reason this should happen. I paid a lot of money for this mattress, and I'm going to seek a refund.
