How to Store a Sofa in a Storage Unit
A sofa is one of the most deceptively vulnerable pieces of furniture you own. It looks solid, feels sturdy, and takes daily abuse without complaint. Underneath all that fabric or leather, though, it is quietly absorbing dust, oils, moisture, and whatever crumbs have escaped the vacuum. When that sofa goes into a storage unit, all of those factors matter more than people expect.
Most sofas that come out of storage damaged were not unlucky. They were stored damp, wrapped incorrectly, crushed under weight, or left without airflow. This guide explains how to store a sofa in a storage unit properly so it comes back out looking like furniture instead of a long term science experiment.

If you are in a hurry, here is the quick version
- Measure the sofa and confirm the unit size before moving day
- Vacuum and clean the sofa thoroughly and let it dry completely
- Remove cushions, legs, and detachable parts and store them separately
- Use breathable layers first and padding second
- Never seal fabric or leather directly in plastic
- Elevate the sofa off the concrete floor and leave space around it
- Store the sofa flat unless upright storage is clearly supported
- Use moisture control and check conditions periodically
- Keep heavy items and strong odors far away from the sofa
Step 1: Measure, plan, supplies
Before touching the sofa, measure it fully. Measure length, depth, and height, including attached cushions or high backs. These measurements determine whether the unit you chose actually works and how the sofa should be positioned once inside. Guessing usually ends with awkward angles and scraped door frames.
Next, plan the route from the room to the storage unit. Measure doorways, hallways, elevators, and stair turns. Decide where the sofa will need to rotate and clear the path in advance. Moving a sofa is much easier when nothing surprises you halfway through.
Gather supplies that protect furniture properly. You will need a vacuum with an upholstery attachment, fabric safe cleaner or leather cleaner and conditioner, microfiber cloths, moving blankets, stretch wrap, breathable furniture covers or sofa bags, packing tape, and pallets or boards for elevation. Add moisture absorbers designed for storage environments, not household air fresheners.
Step 2: Clean it thoroughly
A sofa should never go into storage dirty. Dust and debris grind into fabric over time, and food residue attracts pests. Vacuum every surface thoroughly, including seams, creases, and underneath cushions. If cushions are removable, vacuum the base and frame area as well.
Fabric sofas should be spot cleaned using an upholstery cleaner appropriate for the material. Always test in a hidden area first. Blot gently and avoid over saturating the fabric. After cleaning, allow the sofa to dry completely. Any remaining moisture becomes mildew later.
Leather sofas should be wiped down with a leather specific cleaner and lightly conditioned. Conditioning helps prevent cracking during storage, especially in dry environments. Avoid household cleaners, which damage leather finishes over time.
Step 3: Disassemble what you can and protect what you cannot
Remove all loose cushions, pillows, and throws. Cushions should be stored separately in breathable covers or wrapped in clean moving blankets. Storing cushions flat under weight causes permanent compression, so upright storage with airflow is best.
If the sofa has removable legs, take them off. This reduces stress on the frame and prevents breakage if the sofa shifts slightly. Place legs and hardware in a labeled bag and tape it securely to the underside of the frame or store it in a clearly marked box nearby.
Add extra padding to arms, corners, and trim. These areas are the most likely to be damaged during moving and long term storage.
Step 4: Wrap the sofa correctly
The first layer against the sofa must be breathable. Use a fabric furniture cover, a storage rated sofa bag, or a clean cotton sheet. This layer keeps dust off while allowing moisture to escape.
Next, add moving blankets for protection. Focus on corners, arms, and edges where pressure and friction occur. Secure blankets with stretch wrap, but never apply tape directly to fabric or leather.
Stretch wrap should only hold padding in place. Do not compress the sofa tightly or seal it completely. Plastic placed directly on upholstery traps condensation, which leads to mildew and odors that are difficult to remove.
Step 5: Make sure its supported as you load
Move the sofa using lifting straps or a furniture dolly when possible. Avoid dragging it across concrete or asphalt, which can damage the underside and loosen fasteners. Keep the sofa upright during transport to reduce strain on the frame.
Inside the storage unit, elevate the sofa off the floor using pallets, boards, or plastic platforms. Concrete floors release moisture and transfer cold, both of which damage upholstery and wood frames over time.
Position the sofa so air can circulate around it. Leave space between the sofa and walls, and avoid wedging it tightly between other items.
Step 6: Decide upright or flat for storage
Flat storage is usually the safest option for sofas. Store it on its feet if legs remain attached, or on padded supports if legs were removed. Weight should be evenly distributed so the frame is not stressed.
Upright storage can save space but should only be used if the sofa design supports it. If storing upright, protect contact points with thick padding and brace the sofa so it cannot tip. Never lean it at an unstable angle.
Do not stack boxes or furniture on top of the sofa. Cushions compress, frames twist, and upholstery creases become permanent.
Step 7: Control moisture and odors inside the unit
Place moisture absorbers near the sofa, not directly against it. Use products designed for long term storage and replace them as needed. In humid climates, multiple absorbers may be required.
Avoid storing strong smelling items near the sofa. Paint, fuel, cleaning chemicals, and fertilizers release fumes that upholstery absorbs quickly and retains stubbornly. Keep soft furniture isolated from anything with an odor.
Step 8: Check in occasionally
If possible, visit the unit periodically. Look for signs of moisture, shifting items, or damaged covers. Replace moisture absorbers and adjust spacing if airflow has been reduced. Storing a sofa properly comes down to cleanliness, dryness, breathable protection, smart positioning, and moisture control. Follow those steps in order and your sofa will come out of storage ready to sit on, nap on, or quietly judge your decorating choices just like it always has.
