Summer is officially here, and so are a host of Memorial Day sales. Most big box retailers are rolling out incredible deals to kick off the season. Of course, beloved wholesale warehouse Costco is in on the summer sale action, too: You can score upward of $700 off appliances and other big-ticket items when you shop online or in person. Costco's 2026 Memorial Day sales are set to run until the end of May and into early June, giving customers plenty of time to shop the offerings.

Costco is already known for its discounted membership prices on everything from food to furniture. This Memorial Day, the store is rolling back prices even further. Even non-members can take advantage of these deals while shopping online (just keep in mind, prices at the warehouse may be lower). Whether you're hoping to upgrade your living room or you want to spruce up your patio space, there are plenty of home and garden deals to explore. We rounded up five of the best of Costco's Memorial Day deals for you to consider, from a wooden accent console to a smart cleaning robot.

If you're looking to create a stylish patio space, check out Costco's deal on the Henredon Arlow 4-Piece Outdoor Patio Seating Set. It's currently $999.99 (that's $800 off the original price). Compare this to a similar piece from Joss & Main, which is currently on sale for $1,449. This Costco furniture set features all-weather, UV-resistant light gray cushions. The framing is made from rust-resistant aluminum. It comes with two chairs, one sofa, and one table. It can seat five people comfortably.

The Henredon outdoor patio seat has a 4.6-star rating. One review gushed, "Love this outdoor furniture set! The cushions are comfortable while still being firm enough to provide good support and easy to get up from. The color was exactly as pictured and matched what I was expecting, which was a huge plus. The set also looks very high-end and adds a nice, stylish touch to my patio space. Overall, it feels well-made, comfortable, and looks great outdoors. Definitely a good purchase for the price!" 

Some customers, however, were disappointed by the color. While the photos appear taupe or tan to some, the set actually leans more cool gray. Otherwise, most buyers seem satisfied with the look and feel of these seats.

According to Consumer Reports, Memorial Day is one of the best times to buy an appliance. There are plenty of deals to explore at Costco. If you're looking to cut back on time spent tidying up, consider checking out the retailer's deal on the Roborock QX Revo PLUS Robot Vacuum and Mop. You can get this device for $479.99. That's a $120 discount. A similar product from Roborock is on sale for $849.99 at Home Depot this Memorial Day.

This cleaning robot comes in white or black. It features a HEPA Filter and a rubber anti-tangle brush and side brush. The multi-functional dock helps keep the Roborock poised to clean your floors. Its smart cleaning capabilities allow it to effectively mop and vacuum your entire home. It boosts suction when on carpet and vacuums twice, so it picks up all the dirt and debris. It also holds off on mopping your hardwood or tile until the carpets are clean. It does all this while easily navigating around obstacles like furniture, shoes, or toys.

The Roborock QX Revo PLUS comes with the robot, a dock, four dust bags, six mop clothes, three filters, and cleaning solution. It currently has a 4.6-star rating. One customer wrote, "I've had this for about three months now and I absolutely LOVE this product. So easy to program and control right from my phone. Lots of options and schedules for customization to your routine. I named her Rosie from the Jetsons cartoons. Highly recommend this product! She even goes under the beds which is amazing!"

The Colin Accent Console is currently $449.99 at Costco. That's $100 off the original price. Compare this to the similar Mid-Century Fluted Storage Cabinet Credenza from Nathan James, currently on sale for $944.97. This console is made from poplar solids and acacia veneers. It features a hand-applied warm, walnut brown finish and gold cabinet pulls. At 72 inches long, it has four louvred-style cabinet doors and a spacious cabinet interior.

The top of this piece has a load capacity of 135 pounds, while the shelves can hold up to 50 pounds. Inside, you'll find adjustable shelves as well as cutouts for cable management.

Boasting a 4.7-star rating, customers seem to appreciate the craftsmanship of the Colin Accent Console. "Absolutely love this piece! The quality is outstanding and it looks even better in person than expected. The wood quality is amazing, solid, beautiful, and clearly well-crafted. The design is clean and modern, and it instantly elevates the space," one review shared. They went on to praise the ease of set-up and the polished look.

The Casper Cooling Memory Foam Mattress is currently $110 or $160 off at Costco, depending on the size. This mattress goes from a size full all the way up to California King. A full size is $459.99.

This product currently has a 4.5-star rating. One reviewer wrote, "This Casper mattress sleeps just as comfortably as my Tempur Pedic at one fourth of the cost. I've undergone six back surgeries including a lumbar and cervical fusion, and I'm usually a back sleeper, but sometimes sleep on my side. This mattress is just fine for either position." Some customers did note that the mattress emits an odor when first opened, but said that the smell dissipated after a few hours.

If you're on the hunt for new furniture, consider checking out the deal on the Tayler Leather Sectional. This Aiden & Ivy Furniture piece is currently $700 off at $1,799.99. This is a great deal compared to similar leather products on sale for upward of $2000.

You can get a complimentary swatch from the manufacturer before you purchase to confirm you like the leather color.

This sectional has a 4.7-star rating online. "Great sectional. Firm but comfy, cool, classy looking. The color is a bit unusual which I love, a mix of brown with an olive tint to it. It's still pretty neutral and goes with most decor," one reviewer shared.
