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 THE CULVER IS THE BENCHMARK

Whenever customers begin exploring the King Koil Intimate Collection, this is almost always where we start.

Not because it's the middle model.

Because it's the mattress that best demonstrates what the Intimate Collection was engineered to achieve.

The Culver combines premium natural materials, advanced cooling technologies, handcrafted construction, and King Koil's dual-coil comfort system into a sleep experience that appeals to the widest range of sleepers. It provides the ideal reference point before deciding whether you'd ultimately prefer the firmer Bristol or the plusher Alton.

WHAT CUSTOMERS NOTICE FIRST

Most customers don't describe the Culver as "medium."

They describe it as incredibly balanced.

Your shoulders and hips settle naturally into the comfort layers while your lower back remains comfortably supported. As you change positions, the mattress responds immediately without feeling either too firm or too plush. Many customers who arrive convinced they need an extremely soft or firm mattress find themselves returning to the Culver because everything simply feels proportioned correctly.

WHY IT FEELS DIFFERENT

The Culver's comfort comes from intelligent engineering rather than a single premium material.

Graphite Talalay Latex delivers responsive pressure relief while enhancing airflow. HyperGraph™ Cooling Memory Foam gently cushions the body without creating excessive sink. Premium Silk & Wool naturally regulate temperature and moisture throughout the night.

What truly separates the Culver from many luxury mattresses is its dual-coil construction. The 2,000 Zoned Perimeter Micro Coils create a second layer of adaptive support directly beneath the comfort materials, allowing the mattress to contour more precisely while improving airflow and responsiveness. Beneath them, the 850 ContourFlex® Individually Encased Coil System provides individualized support that promotes healthy spinal alignment and reduces motion transfer between sleeping partners.

Rather than asking one material to perform every job, King Koil assigns each layer a specific responsibility, creating comfort that feels remarkably refined and consistently supportive.

WHO WE RECOMMEND IT TO

The Culver is one of the easiest luxury mattresses we recommend because it accommodates such a wide variety of sleepers.

It's an outstanding choice for combination sleepers, couples with different comfort preferences, back sleepers, and many side sleepers who want pressure relief without excessive softness. Customers who appreciate premium craftsmanship but aren't sure whether they ultimately prefer a plush or firm mattress often discover that the Culver delivers exactly the balanced feel they've been searching for.

THE MATTRESS HOME RECOMMENDATION

If we could introduce someone to the King Koil Intimate Collection using only one mattress, this would almost always be our choice.

The Culver captures everything that makes the collection exceptional. Premium natural materials. Graphite Talalay Latex. HyperGraph™ Cooling Memory Foam. Handcrafted Tailormade Tufting™. Most importantly, its advanced dual-coil comfort architecture creates a level of adaptive support, pressure relief, and responsiveness that many customers have never experienced before.

What impresses us most isn't that the Culver avoids extremes. It's that it demonstrates how thoughtfully engineered materials can work together to create exceptional comfort without compromise. That's why it has become one of the most trusted luxury mattresses in our showroom and the benchmark against which the rest of the Intimate Collection is measured.
