What is the opinion of Reddit about the
VIVOHOME Twin Size Waterproof Mattress Bag, Reusable Mattress Cover with 8 Reinforced Handles and 2 Heavy Duty Zippers for Moving and Storage, 77x42x16 inch?

I got this https://www.amazon.com/dp/B08238Z3PR?ref=ppx_pop_mob_ap_share on Amazon stuffed two old mattresses in in, works well and has held up through 2 years of Boston weather so far with no visible damage. I do keep it under the wall, which has a tarp, but it gets it’s fair share of wetness anyway.

I keep this one close to the wall and use my crash pads for further away, as the foam mattresses aren’t as good for ‘high’ falls.
