Best Mattresses to Buy at Costco: 2026 Buying Guide

Finding the right mattress can make a significant difference in your nightly comfort and overall sleep experience. Whether you prefer a firm sleeping surface, pressure-relieving memory foam, or the balanced support of a hybrid mattress, choosing the right bed requires careful consideration.

For American shoppers, Costco has become a popular destination for affordable mattresses from established manufacturers. Its selection includes brands such as Novaform, Casper, Sealy, Tempur-Pedic, Leesa, and Kirkland Signature.

However, not every mattress is suitable for every sleeper. Firmness preferences, body weight, sleeping position, temperature sensitivity, and budget all influence your decision.

If you are researching the best mattresses to buy at Costco, this guide will help you compare popular options, understand mattress materials, evaluate customer feedback, and make a more informed purchase.

Why Consider Buying a Mattress at Costco?

Costco is known for offering member pricing on household products, including mattresses and bedroom furniture.

Its mattress selection includes affordable foam models, traditional innerspring mattresses, and premium hybrid designs.

Competitive Member Pricing

Costco frequently sells mattresses at prices that may be competitive with other retailers.

Some brands offer models developed specifically for Costco, allowing shoppers to explore different configurations.

However, a warehouse price is not automatically the lowest available. Compare equivalent products and manufacturer promotions before purchasing.

Multiple Mattress Brands

One advantage of Costco is the ability to compare several recognized manufacturers through one retailer.

Homeowners can browse different firmness levels, mattress thicknesses, and construction styles.

Customer Reviews and Return Options

Costco provides customer ratings and product information to support purchasing decisions.

The retailer also maintains a satisfaction guarantee, subject to stated exceptions and conditions.

Understanding the applicable return procedure is especially important when purchasing a mattress online.

Best Mattresses to Buy at Costco in 2026

The following mattress models are among the notable options listed by Costco. These selections reflect their construction, features, and potential suitability rather than independent hands-on testing or a definitive performance ranking.

1. Novaform 14-Inch ComfortGrande Advanced Gel Memory Foam Mattress

Best for: Budget-conscious shoppers who prefer an all-foam mattress.

Novaform is a familiar name among Costco mattress buyers.

The ComfortGrande Advanced model features a 14-inch foam construction designed to combine cushioning with supportive underlying layers.

Its gel memory foam is intended to provide pressure relief and help manage temperature.

This mattress may appeal to people who prefer a more contouring surface without the traditional bounce of an innerspring bed.

However, memory foam firmness can feel different depending on body weight and sleeping position.

Some customer feedback discussed in mattress review resources raises concerns about long-term durability across selected Novaform models.

Buyers should examine reviews for the exact ComfortGrande version rather than assuming all Novaform mattresses perform identically.

2. Casper Cooling Select 12-Inch Memory Foam Mattress

Best for: Shoppers seeking a medium-feel foam mattress.

The Casper Cooling Select is a Costco mattress featuring multiple foam layers.

According to its product specifications, the construction includes breathable foam, pressure-relieving memory foam, zoned support, and a durable base layer.

Its cooling knit cover is designed to improve surface comfort.

The mattress arrives compressed in a box, which can make delivery more convenient.

Couples who prefer reduced motion transfer may find an all-foam design appealing.

However, the mattress may not provide the bounce preferred by traditional innerspring sleepers.

Review individual feedback about firmness and temperature comfort before ordering.

3. Kirkland Signature by Stearns & Foster Lakeridge Mattress

Best for: Buyers interested in a traditional luxury-style mattress.

Costco offers the Kirkland Signature by Stearns & Foster Lakeridge in different configurations.

The 14.5-inch pillow-top model combines a cushioned upper surface with an innerspring support system.

Its listed features include moisture-wicking TENCEL Lyocell, specialized memory foam, an IntelliCoil support system, and reinforced edge construction.

A separate 14-inch tight-top version is available for buyers seeking a firmer sleeping surface.

These mattresses may appeal to shoppers who prefer the feel of a substantial innerspring bed.

Because the mattress is heavy and relatively tall, homeowners should consider bed-frame compatibility and overall bed height.

4. Tempur-Pedic Supreme 11.5-Inch Mattress

Best for: Premium memory foam buyers.

Tempur-Pedic is recognized for its pressure-responsive foam technology.

Costco’s Supreme collection includes medium and firm foam configurations, along with a medium hybrid option.

The all-foam model uses TEMPUR material designed to adapt to body weight, shape, and temperature.

It also features a cooling-oriented cover.

For people who enjoy a close-contouring mattress feel, this may be an option worth considering.

However, premium pricing does not guarantee individual comfort.

Shoppers should evaluate how quickly the foam responds to movement and whether the available firmness suits their sleeping position.

5. Leesa Legend 12-Inch Hybrid Mattress

Best for: Sleepers seeking a softer hybrid feel.

The Leesa Legend available through Costco is marketed as a medium-plush hybrid mattress.

Its construction includes multiple layers of foam and individually wrapped coils.

The coil system is designed to provide support while limiting some movement transfer.

The mattress also includes breathable materials and cooling-oriented comfort layers.

Its softer surface may appeal to certain side sleepers who prefer additional cushioning.

However, people who require a firmer feel may find another model more suitable.

Compare the exact Costco configuration with any similarly named mattress sold directly by Leesa.

6. Sealy Posturepedic Pro Lincoln Heights Mattress

Best for: Shoppers comparing several firmness options.

Sealy has an established presence in the American mattress industry.

Costco lists the Posturepedic Pro Lincoln Heights 14-inch mattress in firm, medium, and plush configurations.

This range allows shoppers to consider different comfort preferences without changing product lines.

A firm model may appeal to certain stomach or back sleepers, while a plush option might feel more comfortable for people who prefer extra surface cushioning.

Customer feedback varies, so pay attention to reviews discussing support, edge performance, and durability.

Choosing the correct firmness is more important than simply selecting the most expensive configuration.

Comparing Different Mattress Types at Costco

Understanding mattress construction makes shopping easier.

Memory Foam Mattresses

Memory foam responds to pressure and conforms around the body.

These mattresses often reduce the transfer of movement between sleeping partners.

However, some sleepers find them warm or difficult to move around on.

Hybrid Mattresses

Hybrid mattresses combine foam comfort layers with an innerspring support system.

They may offer a balance of cushioning, airflow, and responsiveness.

The actual feel depends on coil design, foam thickness, and firmness.

Innerspring Mattresses

Traditional innerspring mattresses use metal coils as their primary support structure.

They generally provide a responsive feel and may offer more pronounced bounce.

Pillow-top versions add extra cushioning above the coil system.

How to Choose the Best Mattress for Your Sleeping Position

Side Sleepers

Side sleepers often benefit from a mattress that cushions the shoulders and hips.

A medium or medium-plush surface may be worth trying, although individual preferences and body weight matter.

Excessive firmness can create uncomfortable pressure points.

Back Sleepers

Back sleepers generally need a comfortable balance between contouring and support.

Many prefer medium to medium-firm mattresses.

A suitable mattress should allow natural spinal positioning without excessive sinking.

Stomach Sleepers

Stomach sleepers may prefer firmer support to limit excessive sinking around the hips.

However, firmness should still provide reasonable comfort.

Combination Sleepers

People who frequently change positions may prefer responsive mattresses that make movement easier.

Hybrid models can be useful options, but foam mattresses may also work depending on their responsiveness.

How Much Do Costco Mattresses Cost?

Costco offers mattresses across several price categories, from budget-friendly foam beds to premium options costing well over $1,000.

Prices vary by mattress size, construction, manufacturer, and current promotions.

For example, Costco has listed the Novaform ComfortGrande in a lower price category than many Tempur-Pedic Supreme configurations.

The Kirkland Signature Lakeridge and Leesa Legend generally occupy higher price segments than basic foam mattresses.

When comparing costs, check whether the price includes a foundation, delivery, setup, or mattress removal.

A lower-priced mattress may become less attractive if additional services increase the final cost.

Prices and promotions can change, so confirm current amounts directly before purchasing.

Understanding Costco’s Mattress Return Policy

Costco is known for its satisfaction guarantee.

However, shoppers should understand the distinction between its general merchandise policy and the 90-day return restriction that applies to specified product categories, primarily electronics and certain major appliances.

Mattresses are not listed among those standard 90-day categories.

Costco’s published merchandise satisfaction guarantee generally applies, subject to exceptions and limitations.

Before ordering, review the specific mattress listing and contact customer service if anything is unclear.

For online orders, Costco offers warehouse returns and eligible online return arrangements.

Do not confuse the retailer’s return policy with the manufacturer’s warranty, which usually addresses defined product defects.

Mattress Delivery and Setup Options

Delivery services vary significantly among Costco mattress listings.

Some premium models include delivery to a selected room, setup, packaging removal, and eligible old-mattress haul-away.

Other models, particularly compressed mattresses shipped in boxes, may include only doorstep delivery.

For example, Casper Cooling Select listings describe doorstep delivery, with setup available separately in certain circumstances.

Check your ZIP code, delivery restrictions, mattress dimensions, and the services included before ordering.

If replacing a heavy king-size mattress, professional setup may be worth considering.

Tips for Finding the Best Mattress Deals at Costco

Start by establishing a realistic budget and identifying your preferred mattress type.

Compare similar sizes and specifications rather than choosing based exclusively on price.

Watch for Costco Direct promotions, manufacturer discounts, and seasonal mattress sales.

Review customer feedback from people with similar comfort preferences.

Also compare prices directly with manufacturers, since some brands offer exclusive trials, accessories, or promotional packages through their own websites.

Finally, remember that mattress quality involves more than thickness.

A supportive 11-inch mattress may be more comfortable for you than a 14-inch model with an unsuitable firmness.

Common Mattress Buying Mistakes to Avoid

One common mistake is buying a mattress simply because it has thousands of positive reviews.

Comfort is subjective, and two people may experience the same mattress differently.

Another mistake is choosing firmness without considering sleeping position and body weight.

Buyers should also avoid overlooking bed-frame compatibility, delivery conditions, and warranty exclusions.

Read recent reviews carefully, especially those discussing long-term comfort rather than only the first few nights.

A mattress should fit your individual needs, not just your budget.
