I have the Dream 12 Inch Hybrid Mattress, Twin Size High Density Foam and Pocket Spring Mattress in a Box, with the CertiPur-US Certified Foam inside. This mattress is super comfortable giving you excellent back and neck support. I love the way it cradles you giving you a refreshed feeling night after night. This mattress is great for anyone that needs extra support during your sleeping hours. I would highly encourage everyone to try this mattress out for that added comfort every night.
