White Glove Delivery - Available -

What is White Glove service?

Standard common carrier delivery options cover the cost of getting an item to your shipping address but our White Glove delivery service does that and more!

The White Glove agent will call to schedule a delivery appointment within a four hour window, which gives you the flexibility to work around your busy schedule and to prepare the space where your item will be placed. Upon delivery, trained professionals will unload your item from the truck, bring it into the room of choice, unpack the item and remove all packaging debris from the premises.

Please note that White Glove delivery will typically add 5 - 7 business days to your order's transit, and only includes 30 minutes of on-site time. If on-site time beyond 30 minutes is required, you may be responsible for additional fees. Additionally, this service does not include set-up of the items being delivered.
