Our beautiful foundation fits any metal frame, but is made especially for ours. Top with your Leesa mattress and you're ready for good sleep.

All your questions answered

1. When will I receive my Leesa Foundation?

Once an order is placed, we need 2-4 business days to build and box your foundation before shipping it directly to you.

We are currently experiencing delays due to COVID-19, so it may take up to 3 weeks to receive your foundation. We will send you an email with your tracking details as soon as your foundation leaves the building.

If you opt for White Glove Delivery for in-home setup, please allow up to 7 additional business days for our partners to receive all of your items, schedule and complete your delivery and setup.

2. How do I clean my Leesa Foundation?

It'd be a little tough to put the four rails in the washing machine (and we don't recommend trying) but you can spot clean the fabric with a mild detergent if you need to remove a stain.

3. Do I need tools to put the Leesa Foundation together?

The foundation consists of four outer rails held together by pins and a center rail that slides into place. No Allen wrench or power tools needed. If you're unsure about how to set up your foundation, give us a call or send us a message. We're here to help!

4. What's the difference between a foundation and a box spring?

Box springs are designed to support inner spring mattresses and can change the way a foam mattress feels to sleepers. A foundation is a hard, firm surface that provides the support a foam mattress needs.

5. Do I need a frame for my foundation?

We recommend putting the foundation on the Leesa bed frame. However, you can place the foundation on the floor or any standard bed frame.
