These Modrest Frasier dining chairs are a great addition to your dining area. To use them, simply assemble them following the included instructions. Once assembled, they're ready for you to sit and enjoy your meals. When it comes to maintenance, wipe the grey PU upholstery with a soft, damp cloth regularly to keep it clean. Avoid using harsh chemicals as they might damage the material. The stainless - steel legs are durable, but try to keep them dry to prevent rust. Also, be mindful of the weight capacity of 300 lbs, so don't overload the chairs. The plastic glides on the legs are there to protect your floors, so make sure they're in good condition. If you need to move the chairs, lift them gently instead of dragging to avoid scratching the floor.
