Welcome to Superco – Southern California's Premier Appliance, Furniture, Mattress and Massage Chair Store

Good selection of mattresses . Go look for Jacqueline. Awesome communication and even showed me different types of firm and extra firm for my back.

I bought some appliances for my new apartments. I’m a college student who just graduated so I couldn’t afford to pay everything at once. Thankfully the staff there was able to help me set up a finance program. Good interest rate and the cashier Christine was so sweet. I would def recommend my friends to buy electronics and furniture from here. Thanks guys~~

Have been buying appliances from Ken the sales manager since 2014 back in their MPK location. Super friendly staffs and always have little surprise gifts for every customer. It’s really hard to find family owned appliances store that provides professional services and price matching. Hope their business stays strong in the years to come. Highly recommend checking them out.

Very fast delivery and shipping process. Jacqueline put me on the list almost immediately after I made the purchase of a massage chair. Everything worked out smoothly and the delivery guys came to install it for me.

Look no further for lower price. Here's the best deals you can find in town or online. Fabulous and honest customers service. Sue helps us pick out the right washing machine at a reasonable price.

We had Superco to do our kitchen remodel in March 2021. Julie helped us to design the kitchen and made a visual representation of it. Julie spent a lot of time going over design ideas with us to make sure our kitchen looked beautiful and functions efficiently for all we need. The contractors were on time everyday and did work efficiently. Especially the contractor, Luke, he was just Top Notch, he was very responsible for his work and even extended his hours to complete everyday work. It was very pleasant to work with them. Thank you Julie and crew for all your amazing work.

I’ve been coming here for years and years now and I’ve always had help from Ken! He would be the first person to greet you when you arrive. I’d always ask him where everything is and he knows what to recommend and knows everything about anything I ask. This time I came in looking for a new refrigerator for our new house. He was able to direct me to where it was, while also suggesting which one I should get. Great customer service as always, and that’s thanks to Ken !

Excellent customer service and great price deal. The sales person, Ken Cheng, is very friendly, patient and knowledgeable. Thank you for taking the time to explain different models of Zojirushi rice cookers, which helped me to choose the best one for me. Definitely highly recommended!

Growing up in the Diamond Bar area, SUPERCO has always been there for us whenever we need an appliance! This is where my Taiwanese parents buys rice cookers, water heaters, couches, pots and pans—what have you. Now we’re the ones shopping here, who would’ve known? We only come in once in a while because their appliances are quality (and rarely needs replacing), but it’s great that SUPERCO is such a cornerstone of the community. Thank you for always being here!

Salesman Ken Cheng was very personable and friendly, answered our questions, and addressed our concerns as well. Especially with the matter of pricing since the price must be right with furniture. He encouraged us to cross-reference prices on the spot, and there really wasn't a need in the end since they had the best prices as it is! Ken also made us aware of all the potential rebates and perks we could get from our purchases, and made sure we knew how to get them. Overall, great experience and would come again!

Great service, great price. Purchased a hot water dispenser and the price couldn’t be beat. I highly suggest looking here before the big box stores

The sales lady, May Zeng, gave a very detail explanation and we got a great deal for our merchant. Excellent service and we definitely will visit again.

Excellent service and excellent pricing! I have come here multiple times and never got disappointed. Our sales Ken Cheng is friendly, patient and knowledgeable. Thanks, Ken!

I went in to look for a new blender for the summer and for my kids to use. Was greeted quite nicely when we walked in and the cashiers were very friendly. Purchased a Cuckoo hand blender for my daughter and she loves it. Easy to use and wash. 5 Stars.

Friendly staff, let 22 of us hang out and escape the heat for a little bit. We were very grateful! Thank you, we’ll be back to buy some rice cookers and other fantastic appliances :)

Julie (the boss) was a pleasure to work with as we were looking for appliances and even a potential kitchen remodeling project. Highly recommend Superco! There is a reason they've been in business for so long.
