The Vevor 2-tier rolling lab cart is built from thickened 201 stainless steel for durable daily use in labs, clinics, salons, kitchens, and other workspaces. It supports up to 220.46 lbs and features reinforced joints for stable, wobble-free performance. Four PU swivel casters provide quiet mobility, while two locking wheels help keep the cart securely in place. The adjustable-height top tray adds flexibility for different users and tasks. Raised tray edges and sound-dampening cotton help keep items secure and movement quieter.
