Storing Oversize items

Storing oversized items can be challenging due to their size and shape. These items can quickly fill up smaller units, often requiring space that accommodates both their dimensions and specific needs, such as keeping appliances upright or protecting furniture.

Use the chart below to find the right unit size for any oversized items you might be looking to put in storage.

Oversized Item

Unit Sizes

Mattresses & Beds

Are you wondering how to store a mattress in a storage unit? Be sure to clean it, use a breathable cover, and keep it flat to maintain its shape. Ideally, your mattress should be stored in a climate-controlled unit since extreme temperatures and humidity can damage the material.

10x10

Refrigerators & Freezers

How do you store a refrigerator in a storage unit? Switch the appliance off and keep it upright to avoid damaging internal components. Keeping the fridge doors open is a good idea to avoid bad odors and mold.

5x10

Kayaks

The best storage for kayaks are climate-controlled units, which prevent the material from warping or breaking. To prevent damage, lay the kayaks horizontally on foam padding or wall mounts.

5x15

Bicycles

Bikes are best kept stored along the edges of a storage unit. Bikes can often be stored vertically or with the use of wall hooks to save floor space.

5x10

Couches & Sectionals

To store a couch in a storage unit, first, clean the couch to remove any dirt or debris. To store a sectional couch, begin by disassembling it if possible, separating the sections to make handling and storage more manageable. Wrap the couch in moving blankets or plastic wrap to protect it from dust and damage. Position the couch in the unit on its side or upright to save space, and ensure it’s away from walls to allow for airflow.

5x10 to 10x15

Lawn Mowers

Drain any gas or oil from lawn mowers and other outdoor equipment before storage. These can often fit neatly in the corners or beneath other larger furniture items, maximizing floor space.

5x10 to 10x10

TVs

Large flat-screen TVs should be stored upright to avoid pressure on the screens, preferably in their original boxes if possible. Make sure they’re covered and placed away from heavy items that could fall on them.

5x10

Washing Machines & Dryers

Disconnect and drain washing machines and other appliances before storing them. Use the storage space inside the washing machine or dryer for smaller, lightweight items to maximize your space usage.

5x10

Dining Room Tables

Tables can be disassembled to save space; remove the legs and store them separately. Stack chairs when possible, using protective padding to prevent scratches.

5x10

Vehicle Storage Units

Vehicle storage sizes range from 20 feet to 50 feet in length. Most cars will generally fit into a 10x20 unit, and most RVs and boats will generally fit into a 35-foot unit. Oversized vehicles or large Class A RVs may need a unit up to 50 feet long.

Vehicle storage units often provide indoor parking spaces or covered outdoor parking to protect against the elements. Some storage facilities offer enclosed vehicle units.
