Hi Anonymous,
This thread may help you and includes some feedback about My Green Mattress which is one of the manufacturing members of the site and offers some of the best quality and value mattresses in the country including several latex options.
Sleeping in a pothole is almost always the result of low quality (density) soft polyfoam in a mattress which is why it’s important to know what is in all the layers inside a mattress so you can tell where the weak link of the mattress is and have a much better idea of how long it will last. Local factory direct manufacturers tend to use much higher quality materials and construction methods so the “sleeping in a pothole” symptoms that are so common in the national brands are far less likely to happen if they even happen at all.
