We really liked the features and natural materials of the ***IKEA Sultan Erfjord Natural Latex Mattress***, but it was a bit too firm for us when we layed on it. However, when mated with the **IKEA Sultan Tveit Latex Pillowtop**, it is just about perfect. This topper contains a 1" layer of latex and is covered with mostly natural materials. As a result, it breaths quite well and is very comfortable. It is provides just enough soft latex to cradle the body and help relieve the stress and critial spots. It is possible to remove the cover so that it can be machine washed. We are very pleased with this pillowtop and would recommend it to any one that has a mattress that feels slightly too firm. This item comes rolled up and weighs 37 pounds, but it is pretty easy to move around. Just be sure that it will fit into your car before you walk out the door with it! Other than that, you won't be disappointed, especially since it costs less than any other 1" topper available on the market that we could find and uses better materials!
