I am still searching for logical explanation regarding this furniture design

Underbed draws are not meant for you to store tools its for bedsheets, or close. I had a day bed with draws under it and thats what I choice at 18 because I had a lot of soccer stuff. I would put in one draw my soccer shorts in another my socks, and in the last drew I put in my bras and panties. The wood was decent it last many years. My daughter had it for 10 years of her life before she asked for a lofted bed to make more room in her room. My boys have drawers in their bunkbed on their stairs. They use it for things like socks, there boxers, one use it for dress up clothes and the other draw is scouting clothes. My husband and I have a bed that lifts so we are trying to get those plastic containers to put under it since it has a lot of space under the bed for us to places or sheets. Not the comforter but this would allow us more space in our closet which is very small for 2 adults to share.

I had drawers under our bed (both sides) when we lived in Monte Carlo, the bed lasted the 31 years we lived there and it was still perfectly functioning. I store the bed sheets and towels in those drawers.

You are right about 'Frequent pulling and pushing may lead to chipping of the plywood' So I prefer to have drawer separated from the bed. I love to have cup board or drawer which stuck in the upper wall.

These days when people have small homes such things are always handy. We have two such beds and we have stored too much stuff in them and we only open them during the season change.

Our bed has sort of two mattresses - a base and a top mattress so there is no room underneath. Luckily we have enough storage elsewhere.

One of my daughters had a bed like this when she lived at home. Her room was small, so there was not a lot of room for chest of drawers. That is where she put her clothes. It allowed her to keep her room very tidy.

Captain's beds (that's what they're called) are practical in small rooms.

I suspect it isn't even plywood - more likely pressed wood with a vinyl veneer - looks nice when new but really doesn't hold up, My husband makes a lot of our furniture and he insists on solid wood, and even picks over the boards to be sure the quality is as high as possible.

My first wife loved those under-bed drawers. She filled them with pillow cases and sheet sets. But we also had a huge mirrored dresser that matched the headboard of the bed. (She had one drawer under the bed filled with medication bottles... I have no idea why she put them down there. She was odd in a lot of ways.) Comforters went on shelves in our walk-in clothes closet. Shoes also went into the closet. I still prefer clothes and shoes in my bedroom closet. Pretty leaves her clean clothes in a chair in her bedroom with shoes scattered around her bedroom. I won't let her leave shoes in the living room. Sometimes I have to holler at her and remind her to put shoes into her bedroom.

Usually those drawers are used for bed sheets, blankets, etc. or clothing.

I have a bad drawer but I am very gentle with it; looking out at my floor too.
