Thought I needed a firmer mattress- WRONG. I needed this!
I called the customer support number and asked if there was a way to make my regular spring mattress firmer with a topper. After the nice lady assessed my needs, she recommended the Talalay topper and said it sounded more like I needed a softer sleep surface. I decided to chance it, and she was completely right. This is the best sleep I've had since my kids were born 5 years ago. Best decision.
