Why you should buy the Serta Perfect Sleeper Innerspring Mattress

The Serta Perfect Sleeper Innerspring Mattress is a kind of mattress that is among the oldest and most traditional options, according to our guide on the best types of mattresses. An innerspring mattress uses coils to provide support while you sleep so that you can move and change your position with ease, and this one by Serta features a total of 825 coils. The mattress also comes with a gel foam lumbar support band that relieves pressure on your lower back and hips for a more seamless rest.

Cyber Monday alert — Get great TV sound with the Sonos Beam 2 at 26% off

A woman touches a Sonos Beam 2 that is below her TV.

It's Cyber Monday and the last big named day of the 2024 deals season (except, perhaps, Christmas Eve). While there are plenty of Cyber Monday deals to be found, the deals people are interested in now tend to shift to the more digital realm. That can mean Cyber Monday AirPods deals and Cyber Monday iPad deals, but it also means that deals at your local retailer will be more technologically oriented. Here, we're looking at the Sonos Beam Gen 2 (or Sonos Beam 2, for short) that we think you'll want for the shiny new TV you picked up over the weekend. TVs, as you've probably noticed, don't have the audio power they did when we were kids and can really benefit from the boost, so get the Sonos Beam 2 for $369 while this deal lasts. That's a savings of 26% or $130 down from its usual $499 price. Tap the button below to grab it now, or keep reading for our take on it.

We're not sure how much time is remaining before these discounts expire or stocks run out, though, so if you see something that you like, you'll have to push forward with your transaction for it as soon as you can.
