Nice but for a regular mattress once sleeping one week on it there was already I dip in the mattress

Dustin B 5/22/2025

Leave a dip in the mattress where you sleep. I'm 5"11 215 lbs. I wouldn't think it would leave a sink home so fast.

from mattress in a bag to Serta

Sean S 5/3/2025

We had a nectar mattress for the past 10 years, it was nice but wanted to support of an inner structure with the comfort of a memory foam. This was the best of both worlds getting the Serta hybrid. The Med firm with pillow top is perfect. I get great sleep, I am a side sleeper, wife is a back sleeper. Both are extremely comfortable.
