5x5
5x5 STORAGE UNIT GUIDE
A 5'x5' storage unit is about the size of a walk-in closet. This size is ideal for holding a small mattress set, a chair or dresser, sports equipment, or a few extra boxes. Renting a storage unit this size could help you free up a cluttered spare room or store seasonal items.

5x10
5x10 STORAGE UNIT GUIDE
A 5'x10' storage unit can hold a queen-size bed, a few chairs and a dresser, and extra storage boxes. Drop off a TV or other large appliances, or park your bike inside a safe, clean spot for the winter. You can even store a desk or extra office equipment. Most units have eight foot ceilings, so a little space goes a long way. If your home or apartment is getting a little too cozy, a five by ten unit from Extra Space Storage could be the answer for you.

10x10
10x10 STORAGE UNIT GUIDE
A 10'x10' unit can hold about as much as an entire family room, or two extra bedrooms. Load in a mattress set, bookcases, tables and dressers. Or pack away that old couch, or set aside old books or appliances you're no longer using. This space is a great way to keep your things safe, secure, and clean. A ten by ten unit can also hold the contents of an entire office, including desks, chairs, files, and storage boxes.

10x15
10x15 STORAGE UNIT GUIDE
A 10'x15' storage unit provides plenty of room to store larger items such as pianos, couches, tables, or big screen TVs. Most units have eight foot ceilings, giving you plenty of room to stack things up. A ten by fifteen unit gives you a secure, tidy spot to safeguard all your goods. It's like having three spare bedrooms that are available whenever you need them.

10x20
10x20 STORAGE UNIT GUIDE
A 10'x20' gives you two hundred square feet of room - that's enough to store the contents of a five-bedroom house. Large appliances are no problem for a ten by twenty unit. Drop off your refrigerator, washer and dryer, or dining room set. Roll in a pool table, or box up all your office paperwork and tax files for secure storage. With eight foot ceilings these large spaces will give you plenty of room for storage - whether you need to stack things up or organize for easy access.

I've been a customer of Extra Space Storage since July of 2012 and I'm impressed with cleanliness, security and friendliness of the staff. Cynthia from Bloomington and Letty at the Claremont facility on Mills Ave. are very accommodating. Marvin on Mills Ave. processed my papers and set up for me the gate passcode; very helpful. The hallways and storage itself are very clean. CCTV everywhere for a peace of mind. I will strongly recommend Extra Space Storage to anyone looking for a place to put their personal items in a well lit, well secured storage.

Spoke to Letty and Nicole several times before I could come in and see the unit. Each time I talked to them, they knew my situation and answered all my questions. I came in to rent and took the 1st unit I was shown. Nicole was great, answered all the questions my dad and I had. I even got a great lock. The facility is close to my school and they have the best gate hours out of everywhere else I checked. I WILL reccommend this to my fellow classmates looking to store their belongings.
