Most people don’t know the most important service a bed frame provides.
A bed frame raises the mattress off the ground to dry out all the sweat you eject into your mattress each night. If this moisture builds up too much over time your mattress can turn into a perfect new world for colonies of mold and mildew.
But like most things, bed frames are overpriced. I once saw a solid wood bed frame for over $1000! If you want a bed frame for less than 40$ with the added bonus of having more storage space then you’ll ever need, build it with 5 gallon buckets!
