So I have been having a bit of back problems and was wondering, how you guys build Lego?

For me most of the time it was sitting on the floor, surrounded by bricks, but I am now in process of putting all on a large table, and sitting on a chair.

What works for you?

P.S. I'm a technic builder, so usualy the building process is a bit trickier than classic Lego.

For me, sitting up straight using proper posture in a suitably supportive desk chair helps me get through those long nights of contemplative construction.  Although I do find that getting up to pour another shot... er stretch my legs from time to time is also very helpful.

I sit on floor (carpet) legs bent ('tailor/Indian/Turkish style') surrounded by a semi-circle of bricks/boxes. Probably not good being hunched over for extended periods but old habits die hard and I have a serious lack of tables and seating in my residence.

I sit in a chair behind a desk, with Lego boxes all around me, building a model/MOC on the desk. Sadly I haven't had the time lately, but that's how I did it. 

This is a difficult one. Ideally you want to avoid hunching over and to reduce the amount of twisting of your spine. However, the volume of pieces that you require for MOCing makes it very difficult keep everything in easy reach. 

A cresent shaped table and a swivel chair would probably be ideal. But, that is a very specific layout that few of us would be able to accommodate in our homes. 

I sit at a low table with space in front of me to build and organize, space on the floor to stack boxes I'm not currently rummaging through, and on my side a storage cart with 10 shallow drawers. It works really well so I can sit up straight most of the time and gives me plenty of almost enough space, but it is a pain (literally) when I drop a piece.

Sitting at my build desk in a swivel desk chair. If I made it to the floor I would never be able to get up again.

Lifetime 28241 Folding Personal Table, 30 by 20 Inch

I used this temporarily as needed and folded it up when done, but after taking it out to build Blue Power Jet, I left it out and assemble things on it. Haven't figured out a better place to put Blue Power Jet and the Lego Dimensions NFC pad.

I also have a Walmart Tritan/Polycarbonate serving tray that I dump parts on to and use to dry parts I washed.

I suffer from spinal disc hernia, sitting on the floor like I used to as a kid is definitely a big no-no. As others advised, sitting at a table with good posture is the way to go for me as well.

Sitting at table would be most comfortable.  Some times I build on floor when my table is full of MOCs awaiting shredding. But I do get up to get parts on a regular basis. Otherwise, I'm down for the count if I stayed too long on the floor.

 

If I'm building with my son, then I'm on the floor. However, being 6'7", my back can't take that for very long. 

For any larger set that I'm working on, I have to be up at a table with proper back support (back cushion). I suffer from mild scoliosis, so if I don't take proper precautions, then I'll feel it the next day in a bad way.

I'm having scoliosis too, have built the tree house on the carpet on New Years Eve. Hell, it was hurting the whole Sunday through. Looks like I'm getting old  Normally I build sitting at a table.

It depends. If I'm building a new set, I can just empty the bags into a few shallow containers and comfortably build sitting before a table.

But if I'm building a MOC and need to search my parts that are organized into little storage containers, I need to stand up and hunch a bit as I peer into or reach for each container. It can get rather tiring.

If it's a small set then I've got a large tray that goes on my lap while I'm on the sofa. With larger sets I generally prefer sitting on our piano stool at the dining room table. No idea why that should be more comfortable than the proper dining chairs (which have backs!) but it works for me. I'm about to embark on building Tower Bridge, so my endurance for the piano stool is going to be thoroughly tested  :)
