A 110 year old yellow pine floor.
Monsters.
Dust bunnies, most likely the remote for the TV and probably a few wallets and sets of keys I lost and could never find…plus, possibly, RTFirefly’s Cat…
Two of those plastic flat bins-on-wheels to store stuff. I just pulled them out over the weekend to store away summer clothes and take out winter clothes.
The rug
Dust bunnies
The pump for our Sleep Number mattress
Probably a few smallish items that got kicked under by mistake
Our bed frame is wood and goes almost all the way down to the floor, so you can’t really put anything under there on purpose (nothing thicker than a thin book, anyway).
Both my kids have underbed storage boxes with their bedding and other stuff. My son’s bed at college is on risers so he has footlockers full of stuff.
Plastic bins filled with shoes and summer clothes.
I read that is “marital.” :eek:
Dustbunnies. There’s only about a 4 inch gap between the bottom of the box spring and the floor so no storage 
That’s why you need the dust bunnies, they eat the monsters. That’s why I never vacuum under there.
I don’t think there’s anything under mine, except the dust bunnies, as I have storage space.
Storage boxes full of yarn, shoes, office supplies and assorted other junk. Board games.
luggage
weights
laundry hamper
dust
dog/cat toys
Guns. Storage boxes with gun stuff in them - cleaning equipment, spare mags, slings, holsters, etc. Maybe a cat or two.
Nothing. My frame sits right on the floor, so there is no way to get anything under it.
Boxes of off season clothes.
Boxes of costumes.
Boxes of stuff inherited from one grandma and one aunt.
I reall need to go through that last box and get stern with it. Some of it is (select examples of) my uncle’s baby clothes.
Nothing, not even dust bunnies. I have pretty bad allergies so my wife vacuums under there bi-weekly while the mattress is leaning against the opposite wall and I’m holding up the box spring. Up until a couple years ago we kept a cardboard box of sex toys and associated paraphernalia, but once the kids got to snooping age, we moved it to a high shelf in the closet. Not as convenient to get to, but worth it.
Hm, sjambok, long sword, AK-47 [legal and licensed], some dust bunnies, a startledcat, the bottle of ibuprofin that went missing yesterday, my favorite pen that I accused mrAru of stealing and taking to work, wad of hair the cat fished out of the trash to play with.
A bleeping mess. Some old papers that I need to go through, some old files that need to be trashed, some weights, a roll-around storage box and 12 tons of dust and dog hair.
I just moved in so absolutely nothing yet, not even dust bunnies.
But I like having monsters under the bed. Much better than in the bed next to me, like when I was married.
A guitar. A really good, small one - that happens to fit into a case that just gets under the bed. I keep the rest of my guitars in their cases in another room, but like having one I can pull out easily when I have a few minutes and can sit on the end of the bed, with one foot propped up on the case…
