This Gel Memory Foam is great for Euro Top models and is a medium firmness. Its a much more breathable type of memory foam which is designed to sleep cooler than most foams. Overall  In our experience in mattress manufacturing over the years, we have not found a better, overall more durable Memory Foam than this. Unlike most Memory Foams sold today, this foam has very little off-gassing and CERTI-PUR tested. It is 4LB density which is a much more dense and durable foam than the average 2LB or 3LB Memory Foam sold in name brand mattresses. We are also very confident that this foam will last for many years to come.
