The convenience of a mattress in a box is unparalleled. Designed for the modern, busy lifestyle, these mattresses are easy to deliver and set up to apartments and inner city homes. Simply unbox, unroll, and you're ready to enjoy a restful sleep. The mattress in a box is not just about convenience; it's about providing quality sleep in the most hassle-free way possible. Pair it with a stylish nightstand and lamp to enhance your bedroom aesthetics.

How Often Should You Change a Mattress?

The lifespan of a mattress can vary based on its material and usage, but as a general rule, you should consider replacing your mattress every 7-10 years. Signs of wear and tear like sagging or lumps are clear indicators that it's time for a new mattress. To extend the life of your mattress, consider our Mattress Toppers and Mattress Protectors.

What Kind of Mattress is Best for Back Pain?

If you suffer from back pain, the type of mattress you choose can make a significant difference. A medium-firm mattress is often recommended for optimal spinal alignment and pressure relief. Our Mattress Buying Guide offers valuable insights into choosing a mattress that can alleviate back pain. Complement your mattress with a supportive bed base for added comfort.

Do You Have to Wait Before Sleeping on a New Mattress?

Only boxed mattresses (Dreamsuite) that come in a box require a few hours to expand fully. It's advisable to wait at least 4-6 hours before sleeping on your new mattress to ensure it has reached its full size and comfort level. Set up your alarm clock and phone charger nearby so you can start your day right.
