Friend is a single mom and admitted she sleeps on the floor of her apartment every night, because there’s only room for 1 twin mattress for her son. Is there anything that would help with comfort that doesn’t take up a lot of room?

I work alongside a woman who is one of the kindest, most hard working women I’ve met. She struggles financially but she busts her ass to be an amazing single mother to her young son, and she recently mentioned that she sleeps on the floor of her apartment every single night because there’s only room for a twin size mattress for her son.

Sleeping on the floor sounds terrible enough on its own, but this woman works as a housekeeper 6 days a week. So she spends 8+ hours a day doing physical labor, bending up and down to put in laundry, do the dishes, go and down stairs with heavy laundry baskets, stand on her feet all day long… I can't imagine doing all that and then coming home exhausted at night, only to sleep on the floor.

I'm hoping/guessing it's carpeted, but is there anything that could possibly help with her comfort? She's not the kind of person to ever ask for help, but she does accept things if they're offered. If there's anything I could get her that would help, I was thinking of saying that someone in my apartment building was getting rid of said item on our community table, and I was wondering if it would help her.

If she says yes I’ll obviously order it (don’t want to order it first only for her to say it wouldn’t be helpful), but I’m just not sure what could help in this situation. It sounds like space is the biggest issue, but she’s also a single mom making very little money, so it’s tough because I’m not sure if something like a nice air mattress would help her and she just hasn’t gotten one because she can’t afford it, or if she’s already considered it but determined there’s not enough room?? Idk I think I’m overthinking this but ever since she casually mentioned that she sleeps on the floor it’s been bothering me and I’d like to help if there’s anything available

Edit: thank you for the ideas so far!! just wanted to mention there’s somewhat of a language barrier between us and she’s a couple generations older than me, so while we’re very friendly at work, we’re not on the level where i feel comfortable talking very openly about this stuff with her. i just don’t want to make her feel uncomfortable or put on the spot so this post is really helpful
