we found the topper didn't provide enough cushion or support. After the first couple day trip we quickly got rid of it and brought in a good quality memory foam mattress. Very happy now. FWIW, I'm about 225 pounds. The stock mattress felt like my hip was touch the plywood (no support). My wife (98pounds) found the original mattress hard, but supportive.
