Saatva

Saatva mattresses are a perennial favorite of "GMA" viewers and a common pick is the Saatva Classic.

This bestseller for the brand is made to order and features a cover made from organic cotton, recycled steel innersprings and comfort foams. Three comfort levels allow you to customize your sleep -- plush soft, luxury firm and firm -- and two height options adds further personalization.

Just for "GMA" fans: Saatva is offering $550 off a purchase of $1,000 or more from Sept. 25 to Oct. 2 at 11:59 pm ET.

Athleisure

Athleisure always strikes a chord with TRS fans, but one product has continued to draw in shoppers: lululemon's align high-rise pant with the 25" inseam.

The weightless, buttery leggings feel like a second skin, making them ideal for low-impact workouts like pilates and yoga. They're available in more than three dozen color options and have a super flattering fit, so try out these must-haves to feel good while you move your body.

Walking pad

Getting your 10,000 steps a day can seem daunting, but a sturdy walking pad allows you to do so in the comfort of your own home while getting some work done or catching up on your favorite TV shows.

The UREVO Smart Walking Pad, which costs less than $200, is a consistent top seller for "GMA" fans thanks to its shock absorption, quiet motor and app that gives walking insights.

Luggage

When it comes to luggage, "TRS" fans are all about value. And you'll be hard-pressed to find a better value than the Zimtown three-piece nested spinner suitcase luggage set for $79.99.

These pieces feature three-digit TSA-approved locks, durable zippers and 360-degree double spinner wheels, a retractable handle with three varying lengths and ultra-strong ABS material so they can stand up to the rough and tumble nature of air travel. Choose from 11 color options like this beautiful rose gold, basic black, dark green and more.

Stanley

When it comes to Stanley, our viewers have two clearcut favorites: the Quencher and the Flowstate. Shop the bestsellers below for yourself or someone you want to give the gift of hydration.

Brooklinen

The luxe linen brand is a longtime viewer favorite, so give Brooklinen a shot for yourself with the perfect introductory item like the Marlow pillow.

Vacuum

The Bissell Little Green Machine is a must for anyone with pets, carpet, or simply the general want to have clean floors! Check out this bestselling model, the Little Green Mini Portable Carpet Cleaner.
