I am a disabled individual living on SSI alone. I am lucky enough to have a partner but we keep finances separate. So, because of chronic pain issues I am no longer able to sleep in a bed we share. I am sleeping in one of his daughters rooms in a cheap twin size bed that doesn't offer the support I crave and nor does it give me space to stretch the legs, which is where the chronic pain is. I don't mean to be picky, but I'm looking for something like a hybrid that is thicker than 6 inches and can hold an overweight old lady. Something on the newer side and clean. We already have an issue with carpet beetles and on occasion, spiders. I'd like to avoid any other kind of insects. It's like the wild kingdom for bugs here. I am just very nervous about it. I've not had to ask for help like this before. I am humbled and embarrassed. I also have no way of picking up said mattress & foundation, so that's a whole other issue. I would like full size because that would work best in his daughters bedroom. No hurt feelings if there's not any available or a reply to this post. Thank you.
