An ergonomic office upgrade can solve two very different problems: easier pointer control at the desk or more structured support while seated. The three M103 choices are closely grouped wireless mice, while the Ergonomic Back Support for Office Chair is a foldable seat cushion and backrest system at a substantially higher listed price. Start by deciding which part of your workstation needs attention.
Quick take
Pick an M103 mouse when your main need is a compact, wireless pointing device. The Q6W0 gives the clearest detailed specification, ERPM carries the lowest listed price, and SXMN is another M103 version with the same core connection and adjustable-DPI direction. Choose the Ergonomic Back Support for Office Chair when you want an armless, indoor seating accessory with a backrest rather than a mouse.
The full range runs from USD 18.01 to USD 207.49, a USD 189.48 spread. That gap reflects a difference in product type as much as price: handheld mouse versus integrated seat-and-back support.

Product notes
M103 2.4G+BT5.1 Dual-mode Ergonomic Office Mice 3-gear Q6W0
The M103 Q6W0 is the clearest fit for shoppers who want stated operating details alongside an ergonomic mouse shape. At USD 18.35, it lists 2.4G and Bluetooth 5.1 dual-mode connection, an up-to-15m transmission distance, and three DPI settings of 800, 1200, and 1600. It also specifies a built-in 500mAh rechargeable battery, silent buttons, and five controls including the roller wheel. The stated curved design and slim, lightweight format suit a portable desk setup. Its key limitation is the listed 1600 DPI upper setting, so its specification is centered on everyday office and entertainment use rather than a higher-DPI mouse configuration.
M103 2.4G+BT5.1 Wireless Dual-mode Mouse Ergonomic Office Mice 3-gear Adjus ERPM
At USD 18.01, the M103 ERPM is the lowest-priced choice in this group and makes sense for a shopper whose priority is keeping the mouse purchase at the bottom of the range. Its description includes 2.4G and Bluetooth 5.1 dual-mode wireless connection, up to 15m transmission distance, three adjustable DPI levels, silent buttons, and a slim, lightweight profile. That combination gives it a direct role in desktop navigation and daily office tasks. The tradeoff is category-specific: the ERPM is a mouse, not a seat cushion or backrest. Shoppers focused on changing chair support should look to the dedicated Ergonomic Back Support for Office Chair instead.
M103 2.4G+BT5.1 Wireless Dual-mode Mouse Ergonomic Office Mice 3-gear Adjus SXMN
The M103 SXMN is the choice for shoppers who specifically prefer this labeled version of the M103 dual-mode mouse. Its description matches the core working approach of the ERPM: 2.4G and Bluetooth 5.1 connectivity, up-to-15m wireless transmission, three adjustable DPI levels, silent buttons, and a slim carry-friendly design. It is aimed at daily office and entertainment needs, with adjustable positioning speed for changing cursor response. The limitation is straightforward on listed price: USD 18.82 makes SXMN the highest-priced M103 mouse here, USD 0.81 above the ERPM. Choose it when the SXMN version is your preference, not when the lowest mouse price is the deciding factor.
Ergonomic Back Support for Office Chair, Seat Cushion with Backrest, Adjustab
The Ergonomic Back Support for Office Chair addresses a different workstation need: chair-based seating support. At USD 207.49, it combines a seat cushion and backrest in one foldable, armless indoor form. The brown unit lists chenille fabric, memory foam fill, and steel as its materials. Its backrest has 12 adjustable positions, which is the central reason to choose it when you want to vary your seated angle for desk work or home use. The built-in steel skeleton is another stated part of its construction. Its limitation is the higher price position and its specific brown, indoor configuration, making it a more focused chair accessory than the compact M103 mouse options.
Final recommendation by use case
For a clearly specified everyday mouse, choose the M103 Q6W0. For the lowest listed price among the mice, choose the M103 ERPM. Choose the M103 SXMN when that particular version is your preference despite its higher M103 price. If your goal is to alter chair seating rather than pointer control, the Ergonomic Back Support for Office Chair is the appropriate match because it brings together memory foam cushioning, a backrest, and adjustable positions.
