I think half rounds would help to avoid bruising oneself on the sharp corners. Of course, most people aren't as klutzy as I am. You could also use garden stools, one-drink cocktail tables or round plant stands if you prefer a more mobile solution.

DMIL uses a couple of one-drink cocktail tables, I think she calls them a tea table (for one cup of tea) in her LR. Pretty handy and you can move them around. Just make sure they are sturdy. I use a small plant stand; I have to say I wouldn't use it by the bed because I don't feel it's sturdy enough.

I like your idea for semi-circular shelves with swing-arm reading lights on the wall. Gives a clear surface for phone, etc, as well as space below for feet, slippers. But I think I'd do two shelves on each side, kind of stacked (one for the book, tablet, or puzzle).

Be sure there's an outlet for charging.

Something like this Annette (size, not necessarily style)

I was going to post a link to something more rustic, but I was blown away by the fact that my search for a round end table came up with the exact table I have sitting in the interior corner of my family room sectional. I can't believe they show a list of $940 and are selling it at $672 -- everywhere. I bought mine at TJ Maxx or Home Goods for $49.99. I had to double check where they had written the price on it with a sharpie underneath. TJ Maxx, Home Goods and Pier One would be good places to look for small side, end, cocktail/martini tables -- whatever you call them. Hope you can find a similarly great find.

The floating shelves are neat too. I just prefer a table that is more flexible and can be used anywhere -- doesn't leave holes in the walls. Especially since you would be mounting into wood rather than drywall.

Found this on overstock. I like the size and shape and could easily paint. So 2 of these would run me around $200, or dh could make the wall shelves for about $10. If he doesn't care about putting holes in the wall then I'll go cheap.

We used the wall shelves in the weekend log cabin we owned several years ago. DH made them out of pine, which made them blend in with the log walls. We used them in conjunction with wall hung lights. We had the space for tables, but I preferred the look over tables.

Dee, great idea. It might be fun to make shelves out of a log on the property and even leave the bark on the edges.

I like a drawer by the bed, or somewhere close to stash things out of sight.

As in inveterate "bumper" I would advise against square end tables, but half round might be cool. Another solution, since you have empty space in the middle of the room to spare, would be to get a headboard with shelves on it. I had one in my tiny guest room and I loved it. Here's an example,

That's just ingenious! Love it! And I like that you're going to keep the light off the shelves allowing more usable space. I'm a fan of keeping everything I can OFF the floor. Makes the space look bigger/less cluttered too.

Hobby lobby has some very tiny tables that would be perfect. I have a few from there for use in my living room for a drink or cup of coffee. All very reasonable prices. Plus there's a 40 % off coupon always on the website to print.

Some cute little tables. There is a hobby lobby somewhere around here I'm sure.
