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.

Are LOUNJ toppers CertiPUR-US®Certified?

Yes, our base foam and our memory foam are both CertiPUR-US® certified safe!

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.

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.
