Professional furniture assembly costs about $50 to $550 on average, depending on the size and type of the furniture you need help with:

• A handyman might only charge $50 to $150 to assemble a small chair or simple bookshelf. 
• Putting together a large dresser or desk usually costs $100 to $550.
• Large desks and office furniture costs $100 to $1,000.

Most furniture takes between 1 to 4 hours to assemble, depending on the size and type. If you plan on hiring a handyperson or professional and want an accurate time estimate, you'll have to give them specific details about the piece of furniture you need help with.

A handyperson or furniture assembler doesn’t usually expect tips, but they may appreciate a $10 to $20 tip, especially if the furniture was difficult to put together or if they had to go up any stairs during the job.

You can always assemble furniture yourself without hiring anyone. However, the DIY route may be time-consuming and frustrating, especially if you're not used to assembling furniture. Screwing legs onto a chair is more beginner-friendly than putting together a complicated desk or cabinet with lots of drawers or doors.

Follow these steps to find the right professional for you:

• Get 3+ estimates from local businesses if possible.
• Read customer reviews on HomeGuide and Google.
• Choose a licensed, bonded, and experienced contractor.
• Make sure you have an estimate in writing.

Ask the following questions can help you choose the right person for the job:

• How much experience do you have assembling furniture like this?
• What tools or materials will you use for this job?
• Do you need my help or input at all?
• How would you handle any potential on-the-job damage?
• Does this quote include trash disposal?
• How long will this assembly job take?
• Do you offer a warranty or some kind of guarantee for this?
• Will you give me a written estimate?
