Costco sells a wide range of mattresses online and, depending on the model, through its warehouses. The selection includes Novaform, Sealy, Beautyrest, Kirkland Signature by Stearns & Foster, Tempur-Pedic, Purple, and other brands, with memory foam, hybrid, innerspring, and different firmness options available.
Prices vary by brand, size, construction, and promotions. Current Costco listings show options from several hundred dollars to premium mattresses costing more than $1,000, so comparing size, materials, delivery, and warranty terms is important before buying.
Costco Mattress Prices by Size
Mattress prices vary by model and size, so there is no single price for every Costco mattress. As a current example, Costco’s Novaform 14″ ComfortGrande Advanced is offered in Twin, Twin XL, Full, Queen, King, and California King sizes.
A current Costco promotion can also change the final price. The ComfortGrande Advanced is included in Costco Direct Savings from July 26 through August 30, 2026, where buying multiple eligible Costco Direct items can provide additional savings.
| Mattress Size | Standard Dimensions | Best For |
|---|---|---|
| Twin | 38″ × 75″ | Kids, teens, small rooms |
| Twin XL | 38″ × 80″ | College rooms and taller sleepers |
| Full | 53″ × 75″ | Guest rooms and single sleepers |
| Queen | 60″ × 80″ | Couples and primary bedrooms |
| King | 76″ × 80″ | Couples wanting more space |
| California King | 72″ × 84″ | Taller sleepers |
For example, the Novaform ComfortGrande Advanced measures 60″ × 80″ × 14″ in Queen and 76″ × 80″ × 14″ in King. The same model is available in Full, Twin, Twin XL, and California King sizes as well.
When comparing prices, check the exact size, mattress model, current promotion, and delivery terms rather than comparing only the brand. Costco’s online selection and promotional pricing can change, so the product page is the best place to confirm the final price before ordering.
Costco Mattress Queen, Full and King Sizes
Queen mattress
A queen Costco mattress is one of the most practical choices for a primary bedroom because it offers more sleeping space than a full without taking up as much room as a king.
Costco offers queen sizes across multiple brands and mattress types. Current listings include queen versions of Novaform and Sealy models, among others.
Full mattress
A full Costco mattress can work well in guest rooms, children’s rooms, apartments, and smaller bedrooms. Availability depends on the specific model, so check the size selector on Costco’s product page before ordering.
King mattress
A king Costco mattress provides substantially more sleeping space and is commonly chosen for couples who have enough bedroom space. King availability and pricing vary by model, and premium hybrid or luxury mattresses can cost considerably more than entry-level foam options.
Are Costco Mattresses Available In Store?
Some Costco mattresses are available at warehouses, but not every mattress sold on Costco.com is stocked in your local warehouse.
Costco’s current listings identify products as warehouse and online, online only, or Costco Direct. For example, a current Novaform ComfortGrande listing is marked as available through both warehouse and online channels, while some other mattress models are specifically marked online only.
For the most accurate local availability, check the product page and select your warehouse. Inventory can vary between locations.
This is especially important if you want to see a mattress in person rather than ordering one online.
Costco Mattress Novaform: Is It a Good Choice?
Novaform is one of Costco’s major mattress brands, with several memory foam and hybrid models available. Its lineup includes the ComfortGrande, Serafina, Advanced Back Support, DreamAway, and other mattresses.
The Novaform 14″ ComfortGrande Advanced uses multiple foam layers, gel-based cooling features, and a 14-inch construction. Costco currently lists it with a 20-year warranty.
Novaform may appeal to shoppers who want:
- Memory foam pressure relief
- Cooling features
- Multiple firmness choices on selected models
- A mattress-in-a-box style purchase
- A range of prices and sizes
However, comfort is personal. A highly rated mattress is not automatically the right choice for every sleeper, so consider firmness and construction rather than relying only on review scores.
When Does Costco Have Mattress Sales?
Costco mattress sales do not follow one permanent nationwide sale calendar. Discounts can appear through Costco’s warehouse savings, online promotions, Costco Direct offers, and special events.
For example, Costco’s current warehouse savings page shows a Novaform 14″ ComfortGrande Advanced Gel Memory Foam Queen Mattress at $399.99 after $100 off, while a Sealy Posturepedic Plus Prosser Hills 12″ Firm Queen Mattress is listed at $599.99 after $150 off. These offers are time-sensitive and can change.
Costco also runs special events with limited-time pricing. A mattress promotion may therefore be available for only a specific period or while supplies last.
Rather than relying on a specific rumored sale date, compare the current price with Costco’s recent promotions and check the official mattress listings before purchasing.
What Do Costco Mattress Reviews and Reddit Users Say?
Costco mattress discussions on Reddit can be useful for discovering real-world questions about firmness, durability, cooling, delivery, and comfort. However, Reddit opinions should be treated as individual experiences rather than definitive product testing.
One person may prefer a firm hybrid while another may find the same mattress too hard. Mattress comfort is especially subjective because body weight, sleeping position, temperature preference, and personal comfort all affect the experience.
A better buying approach is to combine customer feedback with the manufacturer’s specifications, Costco’s product information, warranty details, and Costco’s return policy.
Costco Mattress Store Hours: When Can You Shop In Store?
Costco mattresses follow the regular warehouse schedule rather than having separate mattress hours. Typical U.S. warehouse hours are:
| Day | Typical Costco Warehouse Hours |
|---|---|
| Monday–Friday | 10:00 AM – 8:30 PM |
| Saturday | 9:30 AM – 7:00 PM |
| Sunday | 10:00 AM – 6:00 PM |
These are typical hours, not a universal schedule. Your local warehouse may have different hours, and mattress availability can also vary by location. Some Costco mattresses are available online only, so check the specific product listing before visiting a warehouse.
Costco hours can vary by location and department, so check the latest Costco hours for warehouse, gas station, pharmacy, and membership information.
What Is the Best Costco Mattress to Buy?
The best Costco mattress depends on your sleep style and the type of support you prefer. For a balance of price, cooling, and pressure relief, the Novaform 14″ ComfortGrande Advanced Gel Memory Foam Mattress is a strong option. It has a medium firmness, triple-action cooling features, and a 20-year warranty. Costco currently lists it with sizes from Twin through California King.
For shoppers who prefer a firm mattress, the Novaform Advanced Back Support Plus 12″ Responsive Foam Mattress is designed with targeted back support and firm responsive foam. It is an online-only model and also carries a 20-year warranty.
Costco also carries hybrid and premium mattresses from brands such as Sealy, Leesa, Purple, and Tuft & Needle, giving shoppers more choices if they prefer coils, softer cushioning, or a different mattress feel.
What Is Costco’s Mattress Return Policy?
Costco states that it offers a risk-free 100% satisfaction guarantee on merchandise, subject to limited exceptions. Its current online-order return information says online purchases can be returned to a Costco warehouse for an immediate refund, including shipping and handling fees.
For a large mattress, review the specific return instructions before purchasing. Delivery, setup, haul-away, and return arrangements can differ depending on the product and order.
The return policy is one reason shoppers should keep their order information and carefully check the product’s terms after delivery.
How to Choose the Right Costco Mattress
Start with the way you sleep rather than the brand name.
Side sleepers often prefer a mattress with enough cushioning around the shoulders and hips. Back sleepers may prefer balanced support, while stomach sleepers commonly look for a firmer surface that prevents excessive sinking.
Also consider mattress construction:
- Memory foam: contouring feel and pressure relief.
- Hybrid: combines foam with coils for a mix of cushioning and support.
- Innerspring: traditional spring feel and responsive support.
- Firm mattress: less sinking and a more supportive surface.
- Plush mattress: softer surface with more cushioning.
Your bedroom size matters too. A queen can provide a useful balance of space and price, while a king requires more floor space but gives couples additional room.
