FAQs

What is a mattress topper and do I need one?

A mattress topper is an additional layer of cushioning or support that sits on top of your mattress, designed to enhance its comfort or adjust its firmness. If your mattress feels too firm, a topper can add softness, or if it's aging, a topper can help improve support without needing to replace the entire mattress. Mattress toppers are typically thicker than pads or protectors, ranging from 1" to 4", and are ideal for providing that extra layer of comfort for a better night’s sleep. If you’re looking to refresh your current mattress or change its feel, a topper could be the perfect solution.

What is your return policy?

We offer a 30-day sleep trial, which means you have 30-days after receiving to return it. We think you'll love it, but in the event you have any issues, please reach out to us to start the return process.

How do I know if I need a 2", 3", or 4"?

Choosing the right thickness for your gel memory foam mattress topper depends on your comfort preferences and needs:

2" Topper: Ideal for those who want a slight upgrade in comfort without altering the feel of their existing mattress. It provides moderate cushioning and support, perfect for enhancing a firm mattress.

3" Topper: Offers a balanced combination of softness and support. This is the most versatile option, providing more cushioning for pressure relief while still keeping you well-supported. Ideal for most sleepers.

4" Topper: Best for those who want significant pressure relief and a softer sleep experience. A thicker topper helps with deeper contouring, making it a great choice for people with joint pain or those who need extra softness.

Consider your sleeping position, mattress firmness, and personal preference to choose the right thickness for you!

Can you put a mattress topper on an old mattress?

Yes, absolutely. A key benefit of a mattress topper is its ability to refresh an old mattress. If you're not ready to purchase a new mattress, adding a topper that matches your sleep preferences can provide added comfort and extend the life of your current mattress.

How long do mattress toppers last?

Our LOUNJ memory foam mattress topper will last 5-10 years. We guarantee it for 5. Most poor quality toppers that are cheaper, imported, will only last 1-3 years.

Are LOUNJ toppers CERTIPUR-US Certified?

We've submitted our new foam formulation for review on 2/14/2025. We are confident that it will pass the test with flying colors. Check back for the CERTIPUR-US seal in about 30-60 days.

Do you have a cover for your mattress topper?

Upon request, we can add a bamboo cover to the topper. Please call or email us for more information!

Is the foam safe and hypoallergenic?

Yes! Our gel infused memory foam is certified free from harmful chemicals, hypoallergenic, and odor-free, making it safe for both people and pets.

Is your foam really made in the USA?

Yes! We source the chemicals, pour, cut, and package our foam ourselves to provide you with a clean, durable, and premium product. Our factory is located in Phoenix, AZ.
