120-Night Comfort Exchange

We understand that choosing the perfect mattress takes time. That's why Mattress Home offers our 120-Night Comfort Exchange Program, giving you the confidence to make the right choice for your sleep.

If your new mattress isn't the perfect fit, you may exchange it one time within 120 nights of delivery, provided it meets the requirements of our Comfort Exchange Program.

Mattress Home White Glove Exchange Service

Unlike many retailers, Mattress Home manages the entire exchange process for customers within our local Florida delivery area.

Our professional delivery team will:

  • Deliver your replacement mattress
  • Remove your exchanged mattress
  • Handle all transportation and manufacturer return logistics
  • Complete the exchange during a single scheduled visit

To protect the integrity of the exchange process, exchanged mattresses cannot be brought to one of our stores to avoid applicable exchange fees. All exchanges must be completed by Mattress Home's professional delivery team.

Comfort Exchange Fee

A one-time Comfort Exchange fee applies to all approved exchanges.

  • 7% Comfort Exchange Fee on most mattress sizes.
  • 25% Comfort Exchange Fee for California King and Split California King mattresses due to the additional handling and transportation required.

Delivery charges may apply based on your location.

Nationwide & Outside Our Local Delivery Area

Customers outside Mattress Home's local Florida delivery area—including nationwide deliveries—remain fully eligible for our 120-Night Comfort Exchange Program.

However, customers are responsible for arranging and paying for transportation of the exchanged mattress to the Mattress Home warehouse in Florida. Mattress Home does not coordinate or provide pickup or return logistics for exchanges outside our local delivery area.

Once the exchanged mattress has been received and inspected, your replacement mattress will be prepared according to our standard exchange process.

Exchange Requirements

To qualify for the 120-Night Comfort Exchange Program:

  • The mattress must be clean and free of stains, tears, or abuse.
  • A mattress protector is strongly recommended to help preserve exchange eligibility.
  • Only one Comfort Exchange is permitted per mattress purchase.
  • The replacement mattress must be of equal or greater value. Price differences apply where applicable.

Sleep With Confidence

Our Comfort Exchange Program is designed to give you peace of mind. While most customers quickly find the perfect mattress, we're here to help if your comfort needs change after sleeping on it at home.

Delivery & Setup

exceptional service doesn't end when your purchase is complete—it continues through delivery, professional setup, and ongoing support, long after your new mattress arrives.

Unlike many retailers who rely on third-party delivery companies, Mattress Home owns and operates its own delivery fleet throughout Florida. Our uniformed delivery professionals are Mattress Home employees—not outsourced contractors—and are professionally trained to deliver, install, and care for your purchase with the same professionalism and attention to detail you experienced in our showroom.

What makes this mattress different?

WHY CUSTOMERS FALL IN LOVE WITH THE WILLOW

Many customers begin exploring the Natural Collection with the Terra Medium or Terra Firm.

Then they experience the Willow Haven Plush Euro Top.

That's usually the moment they discover just how luxurious natural materials can feel.

The Willow isn't simply the plush mattress in the collection. It's the mattress that demonstrates how premium natural materials can create extraordinary comfort while preserving the responsive support your body needs for truly restorative sleep.

WHAT CUSTOMERS NOTICE FIRST

The first thing customers notice is how effortlessly comfortable the mattress feels.

Instead of creating the deep sinking sensation common in many plush mattresses, the Willow Haven gently cradles the body while maintaining an almost weightless feeling of support underneath. Customers often describe it as feeling lighter, cooler, and more breathable than they expected, especially after comparing it to traditional foam mattresses.

WHY IT FEELS DIFFERENT

Every material inside the Willow Haven Plush Euro Top has been selected because it contributes to healthier, more natural sleep.

Premium New Zealand Joma Wool naturally regulates temperature and moisture to help maintain year-round comfort. Natural Talalay Latex provides responsive pressure relief while improving airflow and making movement effortless. Sustain™ Memory Foam gently cushions pressure points without overwhelming the natural responsiveness of the mattress.

Rather than relying on thicker foams to create plushness, King Koil uses thoughtfully selected natural materials that allow comfort, breathability, and support to work together as one complete sleep system.

OUR PERSPECTIVE

Customers often ask us if they have to choose between luxurious comfort and healthier natural materials.

The Willow Haven Plush Euro Top proves they don't.

It's one of the mattresses we enjoy demonstrating most because it changes expectations. Many customers assume natural mattresses will feel firmer or less refined than traditional luxury mattresses. The Willow Haven quietly proves the opposite. It delivers exceptional pressure relief, remarkable breathability, and beautifully balanced support while showcasing the benefits of premium natural materials in a way that's immediately noticeable.

If you're looking for the most luxurious comfort experience within the King Koil Natural Collection, the Willow Haven Plush Euro Top is one of the mattresses we're proudest to recommend.
