Don't know what your home looks like, but I know in my place if I didn't have a stand, my bass would be in extreme danger of me, my husband, or one of the dogs tripping over it. You can always turn the bridge into a corner & stand it upright that way, but you're relying on the endpin not to slip. When I was a kid I stored my school bass that way & had a low-flying jet from the nearby air base fly over- the vibrations caused the bass to fall over, wiping out a fish tank in the process. No noticeable damage to the bass, but I certainly wouldn't want to risk a quality instrument. Laying on it's side with the bridge to the wall is always safe, but you need at least 7 feet of unobstructed space. I usually put my bass in one for the intermission at our concerts because it brings the bass up to eye level of the rest of the orchestra members & I don't have to worry about them bumping it while they're mucking around, whereas with some of the members, I'd be pretty worried if I left my bass on it's side 
You touch my bass you die!!!
