Sealy Sundridge vs Serta Five Star Hybrid at Costco Canada (2026): Prices, Specs and Returns
Two of the mattresses Canadians look up most on Costco.ca this month are the Sealy Posturepedic Sundridge, a 14.25-inch medium Eurotop, and the Serta Five Star 14-inch Hybrid, a sale-priced queen-and-king listing. The two product pages describe them in different ways, so comparing them takes some decoding. This guide sets the two listings side by side as Costco.ca showed them on October 30, 2026: prices by size, the layers and coil counts each page states, the firmness labels, the weights, the delivery terms and the return guarantee, with Hamuq's The Original Hybrid Mattress as a non-Costco point of comparison. We have not slept on either Costco mattress.
AI Overview answer
Sealy Posturepedic Sundridge or Serta Five Star Hybrid: which Costco listing is which?
Quick answer: On October 30, 2026, Costco.ca listed the Sealy Posturepedic Sundridge (36.2 cm, 14.25 in., Medium) at $699.99 in twin, $779.99 in double, $829.99 in queen and $949.99 in king, with twin XL also offered, "Online Only", a 3.7 rating from 6 member reviews, and white glove delivery included. The Serta Five Star 35.6 cm (14 in.) Hybrid was listed in queen and king only, at $569.99 in queen after a $150 discount from $719.99 and $639.99 in king after $180 off $819.99, "Valid for orders placed 10/12/26 to 11/01/26", with no reviews yet, the queen showing as unavailable for delivery to the postal code we tested and the king backordered to ship between November 16 and 29. The Serta page lists its layers (two half-inch quilt foams, 4 inches of comfort foam, 1 inch of support foam over wrapped coils, 825 coils in queen) and a 10-year limited warranty; the Sealy page lists "Zoned SealyResponse Pocket Coils", "SealySupport Gel HD Foam" and a "CleanProtect Fabric" cover but no layer heights, and its specifications table does not state a warranty. The Serta is the cheaper listing by $260 in queen while its sale window lasts; the Sealy is the one with member reviews, more sizes and a Eurotop. Costco's return policy page says the company will "refund your purchase price" on merchandise, with listed exceptions that do not include mattresses.
Decide in four questions
Four questions before you choose between the two Costco listings
1. Which size do you need?
The Serta Five Star Hybrid page offered queen and king only on October 30, 2026; the Sundridge page offered twin, twin XL, double, queen and king. A double or a twin rules the Serta out. See prices by size.
2. Is the Serta price a sale price?
Yes. Both Serta prices carried a discount with a window, "Valid for orders placed 10/12/26 to 11/01/26". The Sundridge prices showed no discount line. See the sale dates.
3. Do you want to see how it is built?
The Serta page lists every foam layer by height and the coil count per size; the Sealy page names its technologies and gives dimensions and weights, with the detailed description hosted by a third party. See what each page says is inside.
4. Can you wait?
Costco quoted 10 to 15 business days for the Sundridge; the Serta queen was unavailable for delivery to the postal code we tested and the king was backordered. See delivery, availability and returns.
The two Costco listings side by side
Everything in Table 1 is taken from the two Costco.ca product pages as they read on October 30, 2026, with the queen size selected. Where a page did not state something, the cell says so. Hamuq's The Original Hybrid Mattress is shown as a non-Costco reference from Hamuq's own listing and policy pages the same day.
| Item | Sealy Posturepedic Sundridge (Costco.ca) | Serta Five Star 35.6 cm (14 in.) Hybrid (Costco.ca) | Hamuq The Original Hybrid Mattress (hamuq.mom) |
|---|---|---|---|
| Queen price | $829.99 (no discount line shown) | $569.99 after "$150 OFF" from a regular price shown as $719.99 | $999 listed; site banner that day: "$100 OFF ALL MATTRESSES", applied at checkout |

| Feel, as labelled | "Medium"; "Medium Eurotop" | "Comfort level: medium" | Not restated here; see Hamuq's listing |
| Construction, as the page states it | "Zoned SealyResponse™ Pocket Coils", "CertiPUR-US™ SealySupport™ Gel HD Foam", "CleanProtect® Fabric with MoistureProtect™ Fibres"; specifications list the "Mattress Composition" as "Innerspring" | "1.27 cm (0.5 in.) Five Star quilted gel memory foam", "1.27 cm (0.5 in.) Five Star high-density quilt foam", "10.16 cm (4 in.) Five Star high-density comfort foam", "2.54 cm (1 in.) Five Star high-density support foam", "3-zone individually wrapped coil system"; "Coil count: King: 1,045; Queen: 825; Double: 685; Twin: 475" | Hybrid, as named; no construction details are restated in this guide |
| Queen dimensions and weight | 152.4 cm x 201.93 cm x 36.195 cm (60.00 in. x 79.50 in. x 14.25 in.); 38.1 kg (84.00 lb) | 201.93 cm x 152.40 cm x 35.56 cm (79.5 in. x 60 in. x 14 in.); 52.16 kg (115 lb) | Not stated here |

| Trial or return | Costco return policy: "We guarantee your satisfaction with every product we sell and will refund your purchase price, with the following exceptions"; mattresses are not among the listed exceptions | "120-night free trial on all our products" (refund policy) | |
| Where to see it | Costco.ca listing | Costco.ca listing | Hamuq listing |
Two cautions on reading the table. First, the two pages describe construction at different levels of detail, and a page that lists more layers is not a better mattress; it is a more detailed listing. Second, the Serta's price is a promotion with an end date, so the $260 queen gap can close on November 2.
Prices by size and the sale dates
Costco.ca shows one price per size, and the Sundridge and the Serta do not offer the same sizes. Table 2 lists every size each page offered on October 30, 2026, with the discount line where one was shown.
| Size | Sealy Posturepedic Sundridge | Serta Five Star 14 in. Hybrid | Hamuq The Original Hybrid Mattress (listed) |
|---|---|---|---|
| Twin | $699.99 | Not offered | $799 |
| Twin XL | Offered (price not read) | Not offered | $879 |
| Double / Full | $779.99 | Not offered | $899 |
| Queen | $829.99 | $569.99 ("$150 OFF"; regular price shown as $719.99) | $999 |
| King | $949.99 | $639.99 ("$180 OFF"; regular price shown as $819.99) | $1,189 |
| Discount window | None shown | "Valid for orders placed 10/12/26 to 11/01/26" | Site banner "Mid-Autumn Sale. $100 OFF ALL MATTRESSES. Ends soon!"; the listed prices above exclude it |
At its regular price of $719.99 in queen, the Serta would still sit $110 below the Sundridge. The Sundridge's price range on Costco's search results tile, $699.99 to $949.99, runs from the twin to the king, which is why the twin price is the one most people see first.

What each page says is inside
This is where the two listings differ most, and the difference is in the writing as much as the mattress.
- Serta Five Star 14 in. Hybrid: the Costco page lists four foam layers by height: "1.27 cm (0.5 in.) Five Star quilted gel memory foam", "1.27 cm (0.5 in.) Five Star high-density quilt foam", "10.16 cm (4 in.) Five Star high-density comfort foam" and "2.54 cm (1 in.) Five Star high-density support foam", over a "3-zone individually wrapped coil system" with a stated coil count of 825 in queen and 1,045 in king. Adding the listed foam heights gives 6 inches of foam in a 14-inch mattress. The page also states the cover fabric blend and gives a queen weight of 52.16 kg (115 lb).
- Sealy Posturepedic Sundridge: the Costco page names "Zoned SealyResponse™ Pocket Coils", "CertiPUR-US™ SealySupport™ Gel HD Foam" and a "CleanProtect® Fabric with MoistureProtect™ Fibres" cover, and its specifications table gives a "Mattress Composition" of "Innerspring", a thickness of 36.20 cm (14.25 in.) and a queen weight of 38.1 kg (84.00 lb). It does not list layer heights or a coil count, and the detailed description section is marked as supplied by the manufacturer and hosted by a third party. Its Eurotop label means the top comfort layer is sewn as a raised panel; our guide to pillow top vs Euro top mattresses explains the difference.
- What the weights suggest: the Serta queen is listed 14 kg heavier than the Sealy queen at a similar height. Listed weight is not a quality measure, but it is one of the few like-for-like numbers the two pages share, and a heavier mattress is harder to move; see how to move a mattress.
- Medium and medium: both are labelled medium, Sealy's as "Medium" and Serta's as "Comfort level: medium". Brand firmness labels are not standardized; our firmness by sleep position and body weight chart covers how to read them.
Delivery, availability and returns
Costco.ca sells to members, and both listings were marked for delivery rather than warehouse pickup on October 30, 2026: the Sundridge as "Online Only", the Serta with the note "Item may be available in your local warehouse, prices may vary".
- Sundridge: standard shipping via "White Glove" is "included in the quoted price", which Costco describes as "delivery to the room of your choice, setup on existing frame, removal of packaging", with an estimate of "approximately 10 - 15 business days from the time of order". Haul-away of the old mattress is the paid upgrade: "White Glove with Haul Away is available for $79.99 at checkout".
- Serta Five Star Hybrid: "Standard Delivery Included". With the Toronto postal code the site used for our read, the queen page said "Unavailable" and "Item unavailable for" delivery, while the king page said "Backordered" and "This product is backordered and is expected to ship between 11/16/2026 and 11/29/2026". Availability is checked by postal code at checkout, so yours may differ.
- Returns: Costco's return policy page says, "We guarantee your satisfaction with every product we sell and will refund your purchase price, with the following exceptions", and then lists exceptions such as electronics within 90 days, diamonds, cigarettes and alcohol, custom products and limited-life items. Mattresses are not among the exceptions on the page we read, so the general guarantee applies; the page does not state a mattress trial length. Our guide to mattress sleep trials and return policies in Canada compares store and brand terms.
Hamuq product context
Where Hamuq fits
Hamuq publishes this guide and sells a mattress that competes with both Costco listings, so read this section with that in mind.
- The Original Hybrid Mattress: listed on hamuq.mom at $999 in queen on October 30, 2026 (twin $799, twin XL $879, full $899, king $1,189), with the site banner "Mid-Autumn Sale. $100 OFF ALL MATTRESSES. Ends soon!" shown the same day; any discount is applied at checkout rather than in the listed price. At the listed price it is $169 above the Sundridge queen and $429 above the Serta's sale price.
- Terms: Hamuq's refund policy says "we offer a 120-night free trial on all our products", its warranty page describes a "15-year limited warranty" on mattresses, and its shipping policy says "we offer free shipping on all orders", with possible extra charges for the Territories. That is a stated trial length and a 15-year term against Costco's general satisfaction guarantee and the Serta's stated 10-year limited warranty; the Sundridge page we read stated no warranty term.
- Sizes: Hamuq lists five sizes, like the Sundridge; the Serta listing had two.
Hamuq Inc. sells mattresses, bed frames and bedding. Costco.ca prices, specifications, delivery notes and policy wording are quoted from Costco's pages on the date stated; Costco sells to members and prices can change daily.

Costco mattress questions
Sealy Sundridge and Serta Five Star FAQs
The listings
How much is the Sealy Posturepedic Sundridge at Costco?
Quick answer: On October 30, 2026, Costco.ca listed the Sundridge at $699.99 in twin, $779.99 in double, $829.99 in queen and $949.99 in king, with a twin XL also offered. No discount line was shown, and white glove delivery was included in the price.
How much is the Serta Five Star 14 inch hybrid at Costco?
Quick answer: $569.99 in queen and $639.99 in king on October 30, 2026, after discounts of $150 and $180 from $719.99 and $819.99, "Valid for orders placed 10/12/26 to 11/01/26". Only those two sizes were offered.
Is the Sealy Sundridge a hybrid?
Quick answer: Costco's page lists "Zoned SealyResponse Pocket Coils" and "SealySupport Gel HD Foam", and its specifications call the composition "Innerspring". Pocket coils with foam comfort layers is what most brands market as a hybrid, but Costco's listing does not use that word for the Sundridge, while it does for the Serta Five Star Hybrid.
Which is firmer, the Sundridge or the Serta Five Star Hybrid?
Quick answer: Both are labelled medium on Costco.ca: "Medium" and "Medium Eurotop" for the Sundridge, "Comfort level: medium" for the Serta. The labels come from different brands and are not comparable to the decimal; we have not tested either.
Buying from Costco
Does Costco deliver mattresses to your room?
Quick answer: For the Sundridge, yes: Costco says white glove delivery, "delivery to the room of your choice, setup on existing frame, removal of packaging", is included in the price, with haul-away of the old mattress as a $79.99 upgrade at checkout. The Serta listing said "Standard Delivery Included" and was unavailable or backordered for the postal code we tested.
Can you return a mattress to Costco?
Quick answer: Costco's return policy page says it will "refund your purchase price" on merchandise, with exceptions that, on the page we read, did not include mattresses. The page does not state a mattress trial period, so ask the warehouse or Costco.ca customer service about the process before you buy.
Does the Sundridge have a warranty?
Quick answer: The Costco specifications we read on October 30, 2026 did not state a warranty term for the Sundridge; the Serta Five Star Hybrid page stated "Manufacturer's warranty: 10 years limited". Check the warranty card or Sealy's own site before relying on a term.
Is a Costco mattress cheaper than an online brand?
Quick answer: In queen on October 30, 2026, the Serta at $569.99 and the Sundridge at $829.99 were both below Hamuq's listed $999, Endy's $895 entry model and Douglas's $799 were in the same range as the Sundridge, and the online brands advertised trials of 100 to 365 nights. Our mattress price comparison has the full queen table.
How we know this
Every price, size, specification, delivery note and discount line in this guide was read from the two Costco.ca product pages on October 30, 2026, with each size selected in turn to read its price, and with the site's default delivery postal code (a Toronto code) for the availability messages. The return wording is quoted from Costco's "What is Costco's return policy?" customer service page the same day. Hamuq's prices, trial, warranty and shipping terms are from its listing and policy pages. We did not buy, unbox or sleep on either Costco mattress, and we did not read member reviews beyond the rating and count shown on each page. Costco prices and promotions change often; the Serta discount carried an end date of November 1, 2026.
Comparing Costco's listings with an online brand?
Hamuq's The Original Hybrid Mattress was listed at $999 in queen on October 30, 2026, with a 120-night trial, a 15-year limited warranty and free shipping under Hamuq's published policies.
