I've had this same situation in my life. I don't want to buy flatpack but getting furniture home is hard. I've done these things:

• Hardware Truck - You can rent a flatbed truck from a lowes or Home Depot for like $20/hour. It doesn't have ratchet straps or anything, and it's first come/first serve so they are limited. Easier in the winter tho.

• U-Haul - in town rentals for a truck are like $20 + mileage but they have a reservation system. You know what you're getting but it's a bit more expensive.

• Paid Help. There used to be a reddit guywithatruck or ihaveatruck or something that was happy to help for a VERY reasonable fee.

• Store Delivery - restrict your shopping to stores with delivery. It's not easy or cheap.
