Serta mattress

Sealy mattresses are mostly available through third-party retailers, like Amazon, Walmart and US Mattress. Offerings vary, but they will generally fall within one of these main lines:

Sealy also offers the Cocoon by Sealy Chill Mattress, which is a bed-in-a-box option that you can buy online.

Price range

Most Sealy mattresses fall in the premium price range, though they have some budget options as well. Pricing varies depending on the retailer, but the Response and Conform lines start under $1,000 for a queen, while the Hybrid and Cocoon by Sealy Chill Mattress will run you over $1,000.


Mattress thickness varies depending on the model, with options that are 8, 10, and 12 inches.

Size options

Available mattress sizes include twin, twin XL, full, queen, king, and California king.


You can select your desired firmness for some models. Available firmness levels may vary depending on the retailer.

If the mattress doesn’t specify firmness options, it likely has a medium or medium-firm feel.


Sealy mattresses come with a 10-year limited warranty. Customers can visit the website to initiate a claim.

However, some customers complain that they had a hard time getting the company to honor the warranty when they ran into issues with their mattress.

Customer reviews

Reviews of Sealy mattresses on third-party sites are generally positive.

However, there are some negative reviews about product quality and warranty claim issues. Some reviewers say that their mattress didn’t last as long as they expected.

Where to buy

You can shop for Sealy mattresses online at Amazon, Walmart, or US Mattress. Or, you can buy the Cocoon by Sealy Chill Mattress directly from the brand’s website.

As with Sealy, you can find Serta mattresses from several retailers, including Amazon, Walmart, and US Mattress. You can also buy directly from Serta.

The main lines you’ll find are:

Price range

How much you’ll pay for a Sealy mattress depends on whether you’re buying at an in-person retailer or somewhere online.

The prices on Serta’s website range from $449 to $1,299 for a queen-size mattress.


Mattress thickness varies from 10 to 13 inches.

Size options

Available sizes include twin, twin XL, full, queen, king, and California king.


Serta mattresses come in all firmness levels, from soft to extra firm.


Serta mattresses come with a 10-year limited warranty. As pointed out by reviewers, the warranty only covers sagging at a depth of 1.5 inches. Anything more is out of warranty and not covered.

Customer reviews

Serta mattresses all have overwhelmingly positive reviews. Though, there are some negative reviews on third-party sites, like Consumer Affairs. Most of the complaints have to do with defects and premature sagging.

Where to buy

You can shop for Serta mattresses online at Serta, Amazon, Walmart, or US Mattress.

Picking a mattress has a lot to do with personal preference. Here are a few things to consider.


When shopping for a mattress, the International Chiropractors Association (ICA) recommends choosing the firmest, most supportive model that you also find comfortable.

This means that if a softer surface helps better support your sleeping position, go with that one. Some people like a firmer mattress, but others can’t stand a rock-hard bed. A mattress that’s too firm can increase pressure on your joints and body.

Cooling features

If you like to sleep cool, opt for a mattress with materials that help regulate body temperature as you sleep, like the Cocoon by Sealy Chill Mattress or the Serta iComfort Mattress.


If you’re looking for a mattress that supports spinal alignment, opt for an innerspring or hybrid model.

The ICA says that a queen mattress should have at least 375 coils to provide adequate support. Most Sealy mattresses have well over that many, however Serta doesn’t disclose the number of coils on their site.


If durability is a concern, opt for the thickest hybrid model you can afford. It may also help to get a mattress equipped with handles to make turning or flipping easier.


Sealy offers free shipping if you purchase the Cocoon by Sealy Chill Mattress. Your mattress-in-a-box will arrive sealed in plastic.

Shipping takes about 5–7 days. You can call Sealy to arrange for faster shipping, but you’ll have to pay a fee.

If you’re interested in purchasing another Sealy mattress, you’ll have to buy from an online third-party retailer or in person.


Delivery is free when you buy a mattress directly from Serta. The company also offers white-glove delivery, which includes setup and removal of your old mattress, for a fee.

Shipping takes about 5–14 business days, and the mattress will arrive in a cardboard box. You’ll receive a call to confirm a delivery date and time.

If you’re buying from a separate retailer, delivery may differ.

Both Serta and Sealy mattresses are available for purchase from third-party retailers. The policies outlined below are only valid if you buy directly from Serta or Sealy.


You have 120 nights to try out your Cocoon by Sealy Chill Mattress. During this period, you can decide to return the mattress if it’s not living up to your expectations.

Warranties vary depending on where you buy your Sealy mattress. Mattresses purchased from brick-and-mortar stores, for instance, may not have the same warranty as those purchased online. Most online offerings come with a 10-year limited warranty.


Serta gives customers 120 nights to try out their mattresses. During this period, you can return or exchange it, but the company suggests trying the mattress for at least 30 days before making a decision.

When buying directly from Serta, mattresses come with a 10-year limited warranty.

Both Sealy and Serta use CertiPUR-US certified foams in their mattresses. The foam is tested to verify that it meets specific emissions, content, and durability standards. It doesn’t contain:

  • materials that are dangerous to the ozone
  • mercury, lead, or other heavy metals
  • harmful flame retardants
  • phthalates

These foams are also low VOC, which means they don’t emit harmful volatile organic compounds that can impact indoor air quality.


Sealy has a Better Business Bureau (BBB) rating of A+. However, the company is not BBB accredited.

There have been 30 complaints filed in the last 3 years. Most have been answered, but customers have rejected some resolutions. Most complaints have to do with defects and warranty issues.


Serta has a B rating from BBB and is also not accredited. 40 complaints have been closed within the past 3 years.

Serta hasn’t issued significant recalls within the last 3 years. There also aren’t any recent lawsuits related to business practices or customer-facing policies.

Reviews on both company websites are generally positive. While Serta has a handful of reviews on Trustpilot, there are no Sealy reviews on the website.

Reviews for both brands vary significantly depending on the mattress model. Some models sold by third-party retailers aren’t available on the company websites, and model names vary, so it can be hard to figure out which mattresses reviewers are referencing.

Most complaints about Serta mattresses had to do with premature sagging. Some people also complain about delivery issues.

Negative reviews about Sealy mattresses are generally about warranty issues and mattress defects.

Both Sealy and Serta are well-known mattress brands that have several mattress lines available for purchase. They’re all solid options, but you may want to consider the warranty complaints about Sealy.

If you buy a mattress from one of these brands, make sure you know what you’re buying. If you’re buying from a third-party retailer, find out if the mattress comes with a valid warranty and what that warranty entails.
