Product adds some additional cushion but I would suggest a 3 inch topper for those that arent very budget conscious. For those that do proceed with this purchase, be sure to allow for it to fully expand before using it and or making the bed. It took a full 2 hours for our pad to fully expand. Although the description states that it is meant to be smaller than the mattress, ours hangs over the edge of a standard twin mattress approximately 12 in. on all sides (this isnt a downfall for us, but may be a factor to consider for others).
