I’m in the design stage of building a storage chest that I also intend to use as a bench at the foot of my bed. The sides will be frame and panel construction, and the rough dimensions will be 48” wide, and 18” deep. I’m second guessing myself on the thickness needed for the top. It will be supported around all 4 edges, but needs to support the weight of a ~200lb adult daily without harm. I plan to make it from cherry boards edge-glued together.

I was thinking of making it from 6/4 stock, but I’m wondering if that will be overkill. This is my first project working with hardwood, and this seems like one of those things I will eventually just have a feel for, so I figured I’d ask for advice. Thanks in advance for your help!

Josh

4/4 is fine. It takes a lot of force to break
a 3/4” thick piece of hardwood.

3/4” finished size is plenty strong enough.

Loren:
Awesome link. Thanks for posting.

JoshinDC:
No problem using 3/4 material for the top. I have a tool box about 24×36 with 1/2 ply lid panel that I have no problem sitting on.

4/4 is fine for the top, but generally speaking, thicker tops look better.

The problem with 4/4 for tops is yes you may get a 7/8” if you’re boards are nice and straight and behave well during milling. But that rarely happens so start big and give yourself less headache.

For tops I start with 5/4. Often this is 1 1/8” actual thickness, so material selection is still crucial.

6/4 may be necessary depending on bows, cups, etc, but would be more wasteful.

Me i work with what i got. If I got 5/4 handy then it will be 4/4 finsished. If I got 4/4 then it will be 3/4 finished.

Even if its only 5/8” or 1/2” if engineered properly it will be fine.

Go with your gut.
