by Quick answer: Serta offers a 120-night sleep trial on iComfort mattresses bought directly from Serta.com — full refund, free pickup, no stated return fee. But most iComfort mattresses are sold through third-party retailers (Mattress Firm, big-box stores, locals), and those retailers' own return policies apply instead — with shorter windows, restocking fees, or exchange-only rules. The warranty is a 10-year limited on main lines. Always verify with Serta's site or your retailer before assuming any policy applies to your purchase.

Serta's Direct 120-Night Trial (iComfort Bought on Serta.com)
If you bought your iComfort directly from Serta.com, the current trial window is 120 nights. According to Serta's official copy, returns within the trial period come with a full refund; Serta arranges the pickup and no return fee is stated. There's typically a required break-in period before you can initiate a return — confirm the exact start date on Serta's returns page, since that detail can change.
One limit applies per household per 12 months. And the trial applies to the iComfort line — check Serta's site for any exceptions on hybrid vs. foam models in the current lineup.
Heads-up: Serta's direct channel is one of several ways people buy iComfort. It is not the most common one. If you bought elsewhere, the section below is the one that actually applies to you.
Where You Bought It Matters More Than the Brand Policy
Serta iComfort is widely sold through third-party retailers: Mattress Firm, Costco, Sam's Club, local mattress shops, and department stores. The moment you buy from one of those channels, that retailer's return policy governs your return — not Serta's direct terms.
What that means in practice:
- Trial window: Some retailers match a 120-night window; others run shorter trials (90 nights or less). A few don't advertise a comfort trial at all.
- Refund vs. exchange: Several major retailers offer an exchange or store credit only — not a cash refund — on mattress returns.
- Fees: Return fees, restocking fees, and return delivery charges vary by retailer. Some charge nothing; others deduct a flat fee plus a shipping charge that can reach a few hundred dollars.
- Conditions: Mattress protector use, law-label tags, and minimum sleep time are common requirements. Missing any one of them can void the comfort trial at some retailers.
- Retailer no longer in business: If the store you bought from has closed, there may be no active return policy. The mattress can end up treated as final sale.
The only way to know your actual terms: find your receipt, locate the retailer's current return policy (in writing), and confirm before the trial window closes. Policies update — what was true at time of purchase may have changed.

Warranty: 10 Years, but Read the Fine Print
Most iComfort models carry a 10-year limited warranty. Warranty claims cover manufacturing defects — sagging beyond a defined threshold, cover defects — not normal softening from use or preference changes. The defect threshold that triggers coverage (measured in inches of sag) matters; check your model's warranty card for the exact figure.
Warranty claims are handled through the retailer where you bought the mattress, or directly through Serta if you bought on Serta.com. Keep your proof of purchase. A claim made through a retailer that has since closed can be harder to process, though Serta's own support line is a fallback.
How to Start a Return
- Find your receipt and confirm the purchase channel (Serta.com vs. a retailer).
- Pull up the return policy in writing — check for current terms, not what was advertised at time of sale.
- Confirm whether you're past the required break-in minimum and still inside the trial window.
- Verify your mattress protector use and that law-label tags are intact, if required.
- Contact your retailer (or Serta's returns page for direct orders) to initiate pickup scheduling.
- Ask explicitly: refund or exchange? In writing if possible.
One Alternative Worth Knowing
The "which retailer am I dealing with?" problem is real, especially if you're comparing shopping options. Saatva sells only through its own site, so there's a single policy regardless of when or where you order: a 365-night trial, a flat $99 return fee, and free white-glove delivery with old-mattress removal included. No retailer roulette, no receipt detective work.

FAQ
Does Serta iComfort have a 120-night sleep trial?
Yes — if you bought directly from Serta.com. The 120-night trial applies to that purchase channel with a full refund and free pickup. If you bought from a third-party retailer, that retailer's trial length and terms apply instead, and they vary widely. Check your receipt first.
Can you return an iComfort mattress to the store?
That depends on the store. Some retailers — Mattress Firm, for example — have their own comfort guarantee that includes in-store or pickup returns within their trial window. Others may limit you to an exchange. A few require you to return through their delivery service rather than bringing the mattress in yourself. Contact the retailer where you bought it to get the current terms.
Is there a return fee on Serta iComfort?
For direct orders from Serta.com, no return fee is stated in Serta's current official copy. For retailer purchases, fees vary considerably — from $0 at some stores to a restocking fee plus return delivery charges at others. Confirm before initiating a return, since fees can eat into what you get back.
What if I bought my iComfort from a retailer that closed?
This is a real risk. If the retailer is out of business, their comfort guarantee is generally void — there's no entity to honor it. Your best option is to contact Serta's customer support directly to see if there's any recourse, though they're not obligated to cover third-party retailer guarantees. For warranty claims specifically, Serta is the direct contact regardless of where you bought.
How long is the Serta iComfort warranty?
The typical warranty on iComfort models is 10 years, limited. It covers manufacturing defects like significant sagging (above the defined threshold) and cover issues. It does not cover normal wear, comfort preference, or physical damage. Pull out your model's warranty card for the specific defect criteria — the sagging threshold in particular varies by model and matters for claim eligibility.
Does Serta's return policy apply if I bought iComfort at Costco or Mattress Firm?
No. Those are separate retailers with their own policies. Costco has a general return policy that can be quite generous; Mattress Firm runs its own comfort guarantee program. In both cases, you deal with the retailer, not Serta, for a return within the trial window. Serta only handles direct orders and warranty claims.
