I have used a Thermarest Basecamp for years. Too heavy for backpacking Lately I have added another lightweight pad on top of it. My brother's dog punctured it last trip. The light weight pads are kind of flimsy and expensive.
For gravel beaches I got a 2 pound Thermarest cot. A little hard to set up but very comfortable with the pad on top.
