The top 20 Black Friday bestsellers among Business Insider readers last year

Hulu is one of our favorite streaming services — it's a great way to stay up to date on your favorite cable TV shows sans cable. A basic Hulu subscription usually goes for $7.99 a month, but last year, Black Friday shoppers could get it a year of Hulu for just $0.99 a month. It's no wonder that this was one of the most popular deals.

Trudging through rain, mud, or snow is no problem with L.L.Bean's Bean Boots. The leather and rubber combo keeps your feet warm and dry through all weather conditions. They are seriously durable and comfortable — which explains why they have a cult-like following, and are known to sell out frequently.

With the amount of time we spend sleeping, investing in great bedding should be a top priority — and our readers seem to agree. Last year, the favorites included Parachute's sheets, which come in airy linen, smooth sateen, or lightweight percale. These sheets are pricier than many other options on the market, but their high-quality materials, craftsmanship, and design make them worth the price tag. You can read our review of Parachute sheets here.

Allbirds have been dubbed "the world's most comfortable shoes" for their soft, breathable, and supportive construction. Whether it's the wool runners, loungers, or tree skippers, Allbirds are always a popular choice among Insider Picks readers — including last year on Black Friday.

A 6-foot-long charging cable gives you maximum flexibility to charge your phone, even when an outlet is far away. That plus the quick charging speed makes this a really practical Black Friday purchase.

We're big fans of Brooklinen, the direct-to-consumer brand that sells luxurious bedding for a great value. Last year, our readers loved Brooklinen too, using Black Friday to stock up on options like the classic percale, luxe sateen, and linen sheets.

If the increasing popularity of DNA test kits tells us anything, it's that we're all pretty interested in learning more about our roots. So interested, in fact, that we now even have the option to test the DNA of our pets. Our ever-growing fascination with where we come from explains why these DNA testing kits were top sellers among Business Insider readers last Black Friday.

The Instant Pot will probably be a fan favorite for years to come. After all, it combines seven kitchen appliances in one and can cook meals quickly, all for a reasonable price. Pair it with these accessories to get even more use out of it and expand the recipe possibilities.

Bose makes some of the best noise-canceling headphones out there, but they don't come cheap. The QuietComfort Headphones combine Bose's quality noise-cancellation technology with an extremely comfortable, flexible fit. It's no surprise that our readers jumped on the opportunity to snag these headphones on sale last year.

Braun's electric razors promise a clean shave, even in those hard-to-reach areas. This one even has Intelligent Sonic technology which automatically increases the razor's power when it comes in contact with denser patches of hair. The high-tech gadget is pricey, which explains why so many of our readers took advantage of the Black Friday discount.

Grapes make for a delicious snack, but are easy to choke on — especially for young kids. This little gadget cuts grapes quickly and easily, so you can give your tot a safer snack. It works just as well for adults who prefer cut grapes, and grape tomatoes, too.

A wireless charging pad — which you literally just drop your phone onto when you need a charge — feels futuristic. It's easy to use, makes a great addition to any room, and is a nice gift for tech lovers, so we're not surprised it was a bestseller last year.

The Echo Dot is small but packs a punch with all its capabilities. Use it to call, shop, play music, set a timer, and control other parts of your home by connecting it to other smart home devices. If you need more convincing, nearly 80,000 people have given this convenient device a five-star rating.

The Ring Video Doorbell lets you monitor what's happening outside your front door whether you're in sitting in your home or somewhere far away. Last year, a great Black Friday deal led many of our readers to swap their regular doorbells for Ring Doorbells instead.

As we mentioned before, investing in a great night's sleep is a no-brainer, given how much of our lives are spent sleeping. That's why we think a great mattress is so important — and clearly our readers do, too. Last year, Leesa mattresses came out on top. The Leesa is an all-memory foam option, and the Sapira, a memory foam and spring hybrid — both are seriously comfortable.

You've probably, at least once, been in the predicament of questioning whether or not you unplugged your devices after you've left the house. A smart plug lets you control your outlets from your smartphone, no matter where you are — therefore quelling any fears that you left the toaster on or a hot iron plugged in. It's also compatible with Alexa if you want to go hands-free.

The Philips Hue Ambiance Starter Kit is our top pick for the best smart light bulbs you can buy, and last year, our readers loved them, too. They're easy to set up and use, are compatible with Alexa, and lets you set the right mood with their 16 million color options.

As an owner of a Fire TV Stick myself, I can attest to the convenience of the streaming media player. This device puts all your streaming services, like Netflix, Hulu, HBO NOW, and YouTube, in one place so you can easily navigate through them all. Outside of your home, you can pick up right where you left off by plugging the Fire TV Stick into any TV's HDMI port and connecting to Wi-Fi.

If making restaurant-quality meals from the comfort of your own kitchen sounds too good to be true, you need to try using a sous vide. This little kitchen gadget will help you make delicious, juicy cuts of meat, plus it's super easy for cooks of all levels to use.
