Sam’s Club vs Costco Mattresses: Prices, Brands & Policies Compared

Both warehouse clubs offer mattresses and satisfaction guarantees, but the right choice depends on the exact bed, the total delivered price and how a return would work for your order.

Costco vs Sam’s Club mattresses at a glance

Selection and the mattress itself

Compare the manufacturer, exact model name, size and construction. An exclusive model may have a similar name but different layers or specifications from a national model. Look at height, foam versus hybrid construction, firmness, edge support, foundation requirements and warranty coverage. Inventory changes, and a model available online may not appear in your local building.

Novaform is a brand sold at Costco, while Member’s Mark is Sam’s Club’s brand. Neither name alone tells you whether a particular bed will suit your body or sleep position. Compare individual models, and check the exact listing rather than assuming that two similarly priced mattresses feel alike. Our Novaform vs Casper comparison is a useful starting point for that brand.

Showroom displays vary by location and may be limited, especially for boxed beds. If firmness is important, test comparable mattresses where possible; a pressure-relieving feel for a side sleeper may not suit someone who prefers a flatter, firmer surface. A generous return policy helps, but it does not eliminate the work of moving a fully expanded mattress.

Membership and total value

At the regular US annual rates, Costco lists Gold Star at $65 and Executive at $130. Sam’s Club lists Club at $60 and Plus at $120. Promotions and member benefits can change; check current eligibility and renewal pricing.

Costco Executive advertises a 2% annual reward on qualifying purchases, subject to terms. For example, 2% of an eligible $900 purchase is $18, but one purchase alone may not justify the $65 upgrade. Compare the full year of eligible spending, any reward limits, and the benefits you will actually use. If you already belong to one club, include only the incremental membership cost in your mattress comparison.

Returns, delivery and pickup

Both clubs publish satisfaction guarantees, with exceptions. Before buying, confirm the return terms for the exact mattress and whether you are buying in a building or online. A general guarantee with no stated deadline for most items is not the same as an advertised unlimited mattress sleep trial.

• Costco.com: Costco’s online return instructions allow a warehouse return or an online request. Eligible items may receive a pickup; large items receive additional instructions. Its page says Costco.com refunds include shipping and handling and return shipping is not charged, subject to the policy and item eligibility.
• Sam’s Club: Its returns page describes club and online return options, with exceptions. It says shipping and delivery charges are refunded only when the return results from a Sam’s error or shipping damage. Contact member services about the practical return method for a bulky bed.
• Purchased in person: Ask your club how to return the specific mattress and whether any collection service is available. Do not assume that the online return method applies to a warehouse purchase.

Ask whether the mattress must be clean, whether tags and packaging are needed, who moves it from the bedroom, and what delivery or removal fees are refundable. Keep the receipt and order confirmation. A compressed foam mattress generally cannot be put back in its original box at home.

A practical buying checklist

1. Compare the precise model and size, not just a brand name or firmness label.
2. Add membership, shipping, delivery, setup and old-mattress removal costs where applicable.
3. Check whether the item is available to try locally and whether it fits your base and bedroom.
4. Read the item-specific return and warranty terms. Ask how a large-item return is arranged and whether pickup and fees apply.
5. Compare any direct-brand option on its own terms: trial length, mandatory break-in, pickup and return fees vary by seller.

Frequently asked questions

Which club has the better mattress return policy?

That depends on the order and how you need to return it. Both offer satisfaction guarantees with exceptions; Costco and Sam’s differ on original shipping and delivery refunds. Confirm pickup eligibility and mattress-specific terms before buying.

Is a warehouse-club guarantee an unlimited mattress trial?

Do not assume so. General merchandise guarantees and mattress-specific terms are different from a published sleep trial. Ask the retailer about the model and order channel.

Can I return a mattress bought in a club by mail?

Sam’s Club says items bought in club cannot be returned by mail. For either retailer, check the in-store return process and transportation arrangements before purchase.

Are Novaform and Member’s Mark equivalent?

No. Novaform is a brand carried by Costco; Member’s Mark is Sam’s Club’s brand. Compare the exact models, their construction and warranties.

Can I try the mattress in a warehouse?

Displays vary by location, and some inventory is boxed. Call your local store about the particular model before making a trip.
