Product DescriptionSource Naturals Caffeine + L-Theanine delivers the energy benefits of caffeine with the calming benefits of L-theanine, to help you start the day focused and productive. In contrast to the nervousness that can come from consuming excess caffeine by itself, these two ingredients work together to provide calm, focused energy. Research has shown that caffeine and L-theanine have a synergistic effect on attention and accuracy, and together support healthy focus and memory better than the use of each ingredient by itself. We suggest you start with one tablet but increase to two if the desired effect is not achieved.*

Very happy customer!
Color: Cream White, Color: Cream White
This chair is what you are looking for!!! No serious friends, this chair is everything and so incredibly comfortable! I’m so happy with this purchase. The wood accents I believe are actual wood and the PU leather is gorgeous and seriously looks like real leather. The size is perfect for my frame too. I’m a size medium bottom girly and the curve and level of cushion on the seat is so well executed. The rollability of the rollers are fantastic too, not super loud on our wooden floors and a really smooth glide. Im on the search for a rug to go under my desk but man the patience I used to wait to find this chair truly was worth it. A total lesson on patience and biting when you find the right thing. I think it’s pretty sturdy too. But I’ll report back in a few months. At the moment nothing leads me to be suspicious of a less than long life for this chair.

Good product, could improve backrest depth.
Color: Cream White
Comfortable seat. Stylish looking. Works well. Con is that the backrest is too far away, I had to add a lumbar support pillow. I also added a waffle seat for added comfort as I sit all day in the office. Easy to assemble. Color is nice. Feels sturdy. Rocks back, nice feature. Smooth wheels.

Great production
Color: Cream White
It’s very comfy and doesn’t take too much space like those gaming chairs which I like a lot. I also like the back of the chair is not all the way up but it’s supporting the waist and the back very well. Easy to assemble and very pretty ivory faux leather and wood combination.

Backrest does not adjust in and out
Color: Black
Very comfortable but I wish the back rest was adjustable. It’s too far back to offer any support.
