New mattress for Rob Deptula who's battling ALS

My name is Lisa Nieves and I'm Rob's fiancée and caregiver. Rob has had ALS for 10+ years and the life expectancy is only 2-5 years, and there is NO cure for ALS (Lou Gehrig's Disease). He lives in pain every day and is completely bedridden and can't move or talk. Rob was 188 lbs before ALS, but it stripped his muscle mass down to 110 lbs. He is a true warrior!

This is currently Rob's right shoulder. The wound care specialist said that she could see the bone. Rob is laying on an old used mattress which caused pressure sores on his shoulder and both hips.

Last time Rob was in the hospital he was laying on a Dolphin mattress which is about $28K. But there's no way we can afford that amount. Although, he said it was like floating in the air. We can get a comparable pressure point mattress for $10K-$15K.

Rob deserves to be comfortable, especially since he's bedridden and lost all his motor skills. Please help this ALS warrior. Thank you in advance.
