When I noticed that my mattress was getting a little soft in the middle my sister-in-law showed me what she bought for her bed. She had bought a Convoluted Foam Mattress Pad from a Family Dollar store. This pad is made to fit a full or a queen size bed but you can also get them for twin beds. The Convoluted Foam Mattress Pad is made of 100% urethane foam. This is not a flat foam pad instead it has foam spikes on it. These spikes are supposed to give you a deep massaging sleep.
The Convoluted Foam Mattress Pad is made to support the total body while allowing air circulation. This pad is advertise to reduce discomfort, tossing and turning. It is also advertise to support tired, aching backs. This pad comes with a full three year warranty.
The package claims this is a soy product making it environment friendly.
While out of town on a shopping trip with family I went into a Family Dollar store and I bought two of these. I've put one long ways on the bed and I put the other one cross ways across the middle of the bed where the mattress is starting to sag down a little. I don't know if this mattress pad does all the things it claims but I do know I get a better nights rest without all the tossing and turning. A really good product.
