Costco Adjustable Bed Return Policy & Warranty Explained
Every point below is quoted from Costco's own published policy pages, with the source beside it — because the version circulating in forums is not the version Costco publishes.
Research evaluation. We have not run adjustable bases through a physical lab protocol, so there are no measured noise, durability or motion figures on this page. Ratings are editorial, based on published specifications, warranties, policies and owner feedback.
This page reports retailer policy, not product testing. Policies change without notice — follow the source link beside each point for the current wording.
What Costco publishes
Costco's stated policy is a risk-free 100% satisfaction guarantee on merchandise, with a short list of exceptions that sets a 90-day window.
The 90-day exception list covers electronics categories — televisions, projectors, major appliances, computers, tablets, wearables, cameras, drones, camcorders, MP3 players and cell phones. Adjustable bed bases and mattresses are not on that list, so no published deadline applies to them.
Other published exceptions are diamonds of 1.00ct or larger, cigarettes and alcohol where prohibited by law, products with a limited useful life such as tires and batteries, custom special-order items, and airline and live event items.
Warehouse returns are handled at the Member Services desk and a receipt is helpful but may not be necessary.
Costco Customer Service — Returning an item purchased in a warehouse
An online order can be returned to any warehouse for an immediate refund including shipping and handling, or started from Orders & Returns on Costco.com. Large items generate an email with separate collection instructions rather than a printable label.

Valid reasons listed for an online return include simple dissatisfaction, buying by mistake, a defective or damaged item, the wrong item, duplicates, and refusal on delivery.

Where the warranty takes over
The guarantee and the warranty answer different questions. The guarantee answers "I do not want this". The warranty answers "this stopped working". On an adjustable base the second one is written by the maker, and its two halves rarely match: 7 of the 16 bases we review publish a frame term of 15 years or more, while the motor and electronics term on the same base is typically a fraction of that.
The return guarantee and the manufacturer's warranty are two separate things. Costco's guarantee is about satisfaction; the warranty on the frame, motors and electronics is written by the base's maker and is what covers a motor that fails in year four.
SleepSage editorial explanation
Costco's free lifetime technical support is listed for televisions, computers, cameras, printers and similar electronics, not for bed bases.

Returning a base in practice
- Find the order under Orders & Returns on Costco.com, or take it to any warehouse Member Services desk.
- For a large item, expect an email with collection instructions rather than a shipping label.
- Returning an online order to a warehouse refunds the shipping and handling you paid.
- Return through Costco while the guarantee applies rather than contacting the manufacturer first.
- If the base has failed rather than disappointed, go to the manufacturer's warranty — that route can replace a part without replacing the bed.
- Return through Costco rather than the manufacturer while the guarantee still applies — it is the more generous of the two routes.
- Keep the order confirmation: for a large item the return is scheduled rather than shipped, so you need the order on your membership.
- Check whether the listing is fulfilled by Costco or drop-shipped by the maker, because that changes how collection is arranged.

Questions people ask
How long do I have to return an adjustable bed to Costco?
Costco publishes a risk-free 100% satisfaction guarantee on merchandise with a specific list of exceptions that carry a 90-day window. That list covers electronics categories, diamonds over one carat, tobacco and alcohol, limited-life items such as tyres and batteries, custom special orders, and airline and event items. Adjustable bed bases are not on it, so no published deadline applies to them.
Do I need the original box to return an adjustable base?
Costco says a receipt and original packaging help but may not be necessary for a warehouse return. For a large item bought online, Costco emails collection instructions rather than issuing a printable label, so start the return in Orders & Returns and follow the instructions it sends.
Can I return an online Costco order to a warehouse?
Yes. Costco states that returning an online purchase to any warehouse gives an immediate refund including the shipping and handling you paid. For a base that is only practical if you can transport it, which is why the scheduled collection route exists.
Does Costco cover the motor if it fails in year four?
That is the manufacturer's warranty, not the return guarantee. Frame terms and motor and electronics terms are usually different lengths, and the motor term is the shorter one. Costco's free lifetime technical support is listed for electronics such as televisions and computers, not for bed bases.
Does the Costco guarantee cover a mattress bought with the base?
Mattresses are also outside the published 90-day exception list, so the same satisfaction guarantee applies. The mattress and base may still be separate line items on the order, so check both are included when you start the return.
Can I return it if I simply do not like it?
Costco lists dissatisfaction with the item and buying it by mistake among the valid reasons for an online return, alongside damage, wrong item, duplicates and refusal on delivery.
