You're looking for an interior solid core door if you plan to attach anything more than a hook for a robe.

Yes that is correct. Apparently it’s hard to find “solid”. They have these two options. The stave is basically like slats of wood glued together as apposed to particle which is more like a compressed wood made of lots of tiny bits glued together.

Stave core superior to particle core for screw/ nail holding purposes. Stave core is real wood vs 'sawdust & glue' particle board.

A bad idea for ANY door. Backpacks need a wall, backer board IN that wall, and sturdy hooks. Solid brass........NO NAILS EITHER. Screws with quality coat hooks.

Better to outfit the INTERIOR of the closet ( left side of pic

I would do that to the interior of the closet; however, we will have one shared closet for a family of 4 which will include linens, cleaning supplies and vacuum, coats, outdoor toys and scooters, etc even if we don’t put backpacks I would like to hang the elfa rack and be able to put kids shoes, heads bands, and other little things. I can’t use the hanging system they offer with elfa bc it’s for an 80” door and our will be 95”

In this case? You hide the very ugly, cleaning supplies etc.......and you need an alternate solution unless this is a twelve foot closet : )

Under the bed linen boxes would be a start.

We already have lots of under bed storage too. Even if we don’t hang backpacks I would like to hang some light things like a bar for head bands to hang, maybe some kids shoes, sunglasses etc....does it matter which door I use for that stuff

We can't see your house. Your apartment. It is possible you are asking a miracle from a small space and limited storage, Light weight items can hang on the back of any SLAB solid core mdf door.

Solid core doors are recommended for use on all bathroom and bedroom applications. MDF doors are made from an engineered wood product called medium density fiberboard and are used in paint-grade applications. ... MDF doors are all heavier doors and provide high levels of privacy and noise control.

Thanks Jan. So take home message is that MDF (which I think is the same as particle core?) is sufficient for hanging that rack from the container store as long as I don’t hang anything too heavy? Or are MDF and particle core different? Stave (large slabs of wood glued together) not necessary? Sorry I’m so confused now.

Also yes definitely expecting a miracle. 4 people in 800 square feet. Fun times over here. 😂

Take a trip to a lumber store & look at particle board and MDF. So you know what is what.

They are not the same thing. What both products have in common is both are made of waste products and both have poor fastener holding properties. Also, both products swell up when they get wet and crumble to pieces after they dry out.

Thanks Ci_lantro. So would you recommend the stave door?

Please refer to the specifications shown by the manufacturer you are considering. If it's Masonite, you will find diagrams of just how their doors are fabricated.

There are other criteria that decide what solid door you pick. A particle core will most likely be on a pressed hardboard paint-grade slab. A stave core will most likely be on a stain-grade slab. The design of the door (paneled, routed, etc) may also vary the core depending on manufacturer. So if all new in the house, pick a door that covers most criteria for every door and budget and stick to 1 type. If only 1 or 2 doors for a remodel, match existing which may limit you on type.

Here's a video which will give you more info than you can imagine:

FWIW if your closet is only a standard 24" deep, hanging backpacks (at least if stuff is still in them) will interfere with the hanging coats when the door is closed.
