Excellent customer service
Excellent customer service. They even called me to make sure I ordered the right thing (I hadn’t) and they helped me correct the order over the phone so I got what I needed in a timely manner.

Founded by a US Navy Veteran in 1987 as a waterbed manufacture, Sterling has expanded to offer lines of Innerspring and Latex mattresses featuring interchangeable parts that allow you to extend the usable service life of your mattress from the standard 8-10 year, to 15-20 years and beyond by offering replaceable parts. This practice was held by the EPA to be a waste reducing practice as it prevents millions of mattresses from going to the dump. We pride ourselves on customer service, and hold ourselves to the highest standards of quality and on time delivery. We are FDA Class 1 Certified and HubZone Certified by the Small Business Administration.We are, first and foremost a small business. We may be under new ownership, but our main principles are the same. We will answer all calls during our normal business hours as quickly as we can. If we miss your call, we will call you back. We return urgent calls and email inquiries during weekends and holidays as quickly as possible, even when our office is closed. We are here to support you and our products. Aside from our web chat system that provides answers to common questions, you will not get AI responces from us. Web chat, email all go striaght to a person. Phone calls have a very simple phone tree, and you get a person 95% of the time. Missed calls are returned. We are more than happy to help you make educated decisions. Buying a mattress is incredibly important, and we want to make sure you understand what you are getting into with us. We do not have time limits on calls, and we are happy to answer "Dumb" questions if it helps you make a decision. If you want to talk to a real person, and get real answers, on a top rated product that is actually MADE IN THE USA, and dont want to deal with marketing fluff, give us a try. Our customers like us, not just for our winning personalities, but for our high quality products, and our willingness to explain how things works.

..........and found one offered here that was made in Sweden. Got it fast with no problems for a decent price and it came quickly. Very happy with my purchase.

This is my second purchase from Sterling. I bought a soft sided water bed years ago and it was time to replace the mattresses. Anton was so helpful, ensuring I got the right mattress to fit my frame. We love our Sterling bed!!

A live person answering the phone is awesome. Anton understood my needs and helped me with everything to ensure a smooth solution. My needs were met promptly. The time line that I was given was great. When I picked up my order it was ready sooner than expected. It was even loaded for me.

Hands down the BEST place to buy your waterbed and accessories in the US. The service is OUTSTANDING (Antoine is the best!), the prices are reasonable, and they ship quickly. When you call, you get a very helpful and knowledgeable salesperson—you don’t get that on Amazon. And Sterling makes the best soft sided waterbed out there!

This company does not follow their own return policy. They claim to have a 30-day return policy, but when I tried to return my order, they refused to honor it. The item I received was not as described — it was uncomfortable and the size was incorrect. Even when they “agreed” to take it back, they wanted to charge me for shipping and extra fees. Totally unfair and misleading. Avoid them at any cost.
Response from Sterling Sleep Systems (APPF Inc)Sep 25, 2025
Respectfully, that is a very unfair assessment of what happened. You ordered a 3" thick, Twin Extra Long (38x80) Extra Firm Latex. Which we shipped you. But you cant say it "was not as described". The length and firmness are both correct. You received exactly what you ordered. We only offer 1 size in the "twin" category and that is Twin XL (Extra Long), and we spelled it out on our website. You indicated that it was too long for your use. Which is fine. That alone is a perfectly acceptable reason to return something, and as you indicated, it was within the 30 day window. As it says on our website, that any products that are not a mattress (this is an accessory) has a 30 day return window, you are welcome to return it to us at your expense, and there is a 10% restocking fee.(summarized, but you are welcome to read it for yourself here, https://sterlingsleep.com/pages/shipping-and-return-policy) Most customers that return things to us ask us for a return shipping label, because our shipping charges tend to be a bit lower. We could mark them up, but we don't What we offer comes straight from UPS. In this case, it was around $35 for return shipping and a $30 restocking fee. That covers inspection and a new box for the item if it is returned in new condition. Its entirely possible that we cannot re-box it and may be out the product entirely, but we don't fault you for that. We would usually accept it and refund anyway. We are big fans here of working with customers as much as possible before the sale takes place. We are available to answer questions by phone or email, as well as our chat system when it is active on our website, to address as many concerns as we can before an order is even placed. I am very sorry this didnt work out for you the way that you hoped it would, however, in all of our interactions today, we never told you, you could not return it. We offered you an exchange, which was my mistake since we didn't have the smaller size in stock. We offered to cut it down to the size you wanted, and not charge you for the work if you paid the shipping. We offered you discounted return shipping tags to lessen the financial burden. You are still very welcome to return this to us if it is not to your liking. The shipping label i sent you earlier is still valid if you change your mind. I am not going to cancel it because of a 1 star review. We have a very long history of offering very high quality products, and working directly with customers. We imported the foam in this case, but final processing and shipping was done here in our factory, and all communications was through our office here in California. We take a lot of pride in what we do, and take it very personally when someone says we didn't meet their expectations. The only thing we can do here is present the evidence of what actually happened, and hope that this customer, as well as others that might read this complaint get a better feel for what actually occurred.
