All Your Questions Answered!

How firm are your mattresses?

Our mattresses are available in plush, medium-firm, and firm options — each designed for different sleep preferences.

How does the 100-night trial work?

At SleepMart, we want you to feel confident about your sleep. That’s why every SleepMart mattress comes with a 100-night risk-free trial. We recommend giving your mattress at least 30 nights to fully adjust—just like breaking in a good pair of shoes. If after that you feel it’s not the perfect fit, simply reach out to our Customer Care team anytime before the 100th night. We’ll guide you through the quick return process and arrange for a hassle-free pickup. Where possible, returned mattresses are donated to local charities, at no extra cost to you.

Do all SleepMart mattresses come with a warranty?

Yes! Every SleepMart mattress is backed by our 20-year warranty when purchased through SleepMart.com or an authorized retailer. This long-lasting coverage gives you peace of mind, knowing your investment in better sleep is well protected.

What makes a Plasmabed mattress different from other mattresses?

Plasmabed mattresses are designed with over 20 years of expertise and advanced sleep technology. We use Nano Technology for a cleaner, more breathable surface, the Frosty layer for cooling comfort, and our exclusive Gelastic™ Comfort System for targeted support and pressure relief.

Is the Frosty layer really effective for hot sleepers?

Yes! The Frosty layer is engineered to draw heat away from your body, helping you stay cool throughout the night. It’s ideal for those who tend to overheat while sleeping or live in warmer climates.
