I'll build whatever you want, but it's gonna cost ya.

I wanted a kitchen table to fit my area perfectly. So I had one custom made. It is basic a natural cherry table with two benches no backs and I spent 2700. on i t but to me it was worth every penny.

There are coffee tables with tops that lift -- not sure about the sizes -- but do have a talk with someone at Lowes and/or Home Depot about what hardware they sell that would accomplish the lifting motion you want and then consider making a DIY project. Some Home Depot stores have weekend classes for those that are DIY inclined.

Found these:

I'd try making one, myself, but I know not everyone wants to do that. Maybe you could buy one you like that's 20" tall, and trim the legs, though? That shouldn't be too difficult to do. You can buy little feet that screw into the bottom of the legs and twist to adjust the height, so it wouldn't matter if one of your cuts was off by a sixteenth of an inch or something, you'd be able to level it with the adjustable feet. Or just buy a set of legs in the correct height; there are tons of places online that sell all kind of different legs.

And keep looking, of course, because I'm sure you're not the only person in the world who's ever wanted that (although I know it can feel that way, sigh).

This one is 23.6"L x 23.6"W x 18.3"H

Found some that were close, maybe you could give a little on height or width?

When I was looking for something that would provide a dining table when needed for dinners with guests and serve as a coffee table when I didn't need the extra dining space I found a fabulous mid century elevator coffee table.

It is a coffee table that lifts to dining table height and has 2 leaves that widen it to dining table width.

Just looked and there is one on Etsy:

The Latitude Run table is the only new table in the ones shown above that is really a dining table for anyone not sitting on the couch. The couch ones are good for two or three people at best, since they cantilever over to the couch from the center coffee table area and leave all the other chairs with no place to set anything.

I love the Kai Kristiansen Elevator Table, and if you can fit it in and afford it, jump on it! That is an heirloom! I looked at a few MCM lift tables online when I was looking for my lift coffee table, and did not see one like that. The ones I saw had scissor-lift legs and would not have been as durable. Nor were they as beautiful!

I got a table that had the same idea as this one Sherry Coffee Table at Wayfair for $580.

But mine rotates a half turn and opens like a book, which doubles the table size. I can have the table either small or large at any height between 11" and 30" and it really is a breeze to lift and convert. I got mine at ExpandFurniture.com, and they have this 39 x 22 ish Coffee Table that rises from 10" to a Dining Table at 30" and doubles in size.

It is small enough to be practical in your space, but provide a real table for dining that all knees can tuck under (unlike the Latitude Run and even Expand Furniture's version of it). It is $799, expands to 39" x 45" (which is still half what I paid for mine, that expands to 59" x 43"). Even if you do decide to stick to tables that make a little tabletop that rises and moves over to the couch, look at what Expand Furniture has. Check into what kind of wood product the different tables you consider are made of. I would not expect a moving mechanism in an MDF or particle board to last. The tiny wiggles with each movement would loosen it sooner or later.

Another option for a lift table to bring the table top toward those sitting at the couch is to look at used furniture stores. These tables were popular in the 1990s, but many did not see a lot of use. I see them in my favorite used shop regularly.

There is another thought. Get the coffee table that you want with storage and find space for a side table that converts to a full size dining room table when needed.

My sister has one that is older (from the turn of the century) that is mahogany. They take almost no space and you can use them to place a few pretty things on or as an entry table to set your keys and purse when not in use as a dinning table.
