Product Q&A

Ask a Question

Can you please check with the manufacturer to see if all their products contains charcoal (to help with off-gassing) as I know one Spinal Response mattress we have does? When I purchased mine they only had a couple different mattresses available and now they have over 40 so the item descriptions have changed and many of them do not mention charcoal. weasle34 on May 11, 2013

Answer This Question

Hello weasle34! This mattress does contain charcoal in the foam which does minimize the "off gassing" commonly found in many memory foam products. I hope this helps. Thanks for shopping with us. overstockcustomercare1 on May 16, 2013
