The Days Bariatric Walker in the Low Mack configuration is a four-wheeled seat walker built on a heavy-duty aluminium frame for users who need more capacity than a standard rollator provides, with a safe working load of 150 kg. The padded seat is 50 cm wide and sits 49 cm from the floor, and a padded backrest fits behind it on easy-release pins so that it can be taken off when the walker is folded. Handbrakes lock to hold the walker still during transfers, and the ergonomically shaped handles adjust from 75 to 86 cm. The 20 x 5 cm (8 x 2 inch) castors are specified for rolling over varying terrain. A removable shopping basket carries belongings and comes off for folding. The frame measures 70 cm wide and 64 cm deep and weighs 9.4 kg.

The lower seat and handle settings are what separate this version from the taller High Mack, which makes it the better match for shorter users who need bariatric capacity. A reinforced frame rated to 150 kg, brakes that lock for transfers and large castors together make resting and moving about more practical, while the removable basket and backrest keep folding simple.
