Very comfortable
Mattress is extremely comfortable and so glad there are 2 sides. We thought we wanted firm, but were wrong. After 3 nites of pain, we flipped it and wow! However, it is incredibly difficult to flip since the mattress is very flimsy and heavy. If we had known we needed a medium firmness, we would have gone with a hybrid. We also bought the frame and base from latex4less. Frame was tricky since instructions didn't match what we received but customer service was great and got us on track. The base doesn't really fit the frame. It's 2 inches narrower than frame and 3 inches narrower than mattress
