In accordance with one example, the first layer of foam material includes a first side with a plurality of protrusions and a plurality of channels with the second layer of elastomeric gel material disposed within the plurality of channels. In accordance with another example, the first layer of foam material includes a first side with a plurality of protrusions and a network of channels surrounding at least one of the plurality of protrusions with the second layer of elastomeric gel material disposed within the network of channels. A third layer extends over the first support surface of the protrusions and the second support surface of the second layer of gel material. In accordance with yet another example, the first layer of foam material includes a first side with a plurality of protrusions extending through corresponding Shapertures of the second layer. In accordance with further examples, methods of making a support structure with a first layer of foam material and a second layer of elastomeric gel material are provided.
