The 20 best-selling products from last year's Black Friday - including the ones that surprised us

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. With nearly 80,000 people giving this convenient device a 5-star rating, it's no wonder it was a top-selling product last year.

They're also compatible with Alexa, Google Assistant, and Microsoft Cortana if you want to go hands-free.

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.

With the amount of time we spend sleeping, investing in great bedding should be a top priority — and our readers agree. Last year, our readers loved Parachute's sheets, which come in either an airy linen, smooth sateen, or lightweight percale, and so do we.

Trudging through rain, mud, or snow is no problem with 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 so many tablet options on the market, the Fire 7 Tablet stands out for having the same processor, memory, and storage capacity as the Fire HD 8, but being a little more budget-friendly. If you need a tablet, this one's a good choice for casual browsing and streaming.

This one mat can become a diaper clutch, changing station, or playmat — plus, it folds small enough to fit in a diaper bag. With it's multiple uses and ease of use, it's a great value at just under $30.

From custom pillows, to mattresses, to adjustable bed frames, there are so many products that aim to help you get a great night's sleep. This unique memory foam pillow is one of them. It's made with an elastic memory foam mix and is fully adjustable — just unzip the cover and add or remove foam until the pillow feels just how you like it.

Last year, the Echo was a big hit. The smart speaker comes with Amazon's perennially popular smart assistant, Alexa, built right into the hardware. That means you can call on Alexa to play music, make calls, set alarms, ask questions, control connected devices, and just about anything else.

It features a speaker powered by Dolby and is currently available in six styles, including fabrics and wood veneers — for the holidays, Amazon partnered with (RED) on a limited-edition red Echo to support the fight against AIDS.

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 an essential — and clearly our readers do too. Last year, our readers loved Leesa mattresses. They have the Leesa, an all-memory foam option, and the Sapira, a memory foam and spring hybrid — both are seriously comfortable.
