The surface you sit on should be part of the choice from the start. Yet “mesh chair” can describe the back alone, with a cushion beneath you. Looking at the seat and back separately makes it easier to choose a chair you actually want to examine.
Shortlist the original SIHOO Doro C300 for a mesh seat and back. Consider the original Branch Ergonomic Chair for a foam seat with a mesh back. The material describes the approach; the shape and adjustments still need to suit you. Neither option establishes which seat will feel comfortable to you.
Separate the seat from the back
The US original SIHOO Doro C300 listing identifies mesh for both surfaces. That gives a reader seeking an open seat a specific model to investigate, rather than relying on a general “mesh” label.
The original Branch Ergonomic Chair combines a mesh back with a foam cushion. It is a relevant alternative when you want to try padding beneath you without ruling out a mesh back.
Keep the versions distinct at the seller. The original C300 is not the C300 Pro or Pro V2, and the original Branch is separate from Pro and Lite. A useful shortlist can become the wrong purchase if another version's features are assumed to be included.
Decide which surface you want to try
A mesh seat has an open structure through which air can pass. Consider original C300 if that is the kind of surface you want to examine. Its construction does not tell us how cool it will feel in your room or how the edge and tension will suit you.
Branch's cushion gives you a padded surface to try. “Cushioned” does not establish softness or comfort for everyone: the particular seat's shape, cover and firmness remain part of the decision. The mesh back and padded seat are a combination of two separate material choices.
Let the chair come toward your work
The seat also needs to work with the way you approach the desk. Branch describes seat-depth adjustment and adjustable, removable armrests on the original Ergonomic Chair. Those are reasons to examine whether that chair can accommodate the sitting position and desk access you want; they do not guarantee fit.
Look at the actual model's controls and seat shape. Can you approach the keyboard as intended, sit back without being pushed away from your work, and position the arms where you need them? Take those questions to the exact seller configuration instead of choosing on material alone.
A useful shortlist can include a mixed design
Imagine a reader who likes the idea of a mesh back but wants to try a padded seat. Original Branch becomes a candidate because its construction matches that preference. Another reader may want to compare an open seat with their current cushion; original C300 provides that documented approach.
These are possible buying situations, not our experience of sitting in either chair. For a separate model comparison, C7 versus original C300 develops the differences between those named chairs. It is optional reading, not a required detour before either seller.
Keep a good chair, or try the exact alternative
A different material alone need not replace a chair that already suits your routine. If you are changing chairs, try the exact model where possible and confirm the selected order's return conditions. Do not assume an assembled home trial or free return shipping.
Choose original C300 when its mesh seat is the approach you want to investigate, then confirm the model, configuration and fit at SIHOO. Choose original Branch when you want to examine a foam seat with a mesh back, then check its adjustments and current order terms at Branch. Let that specific preference lead to the seller choice below.
