Saatva Foundation: Overview
Pros
- More durable than a box spring
- CertiPUR-US foams add cushioning
- Breathable organic cotton cover
- Industry-leading perks
Cons
- Bed Frame sold separately
- Rarely discounted on its own
- Could make your mattress too firm
The Saatva Foundation is crafted from premium materials like CertiPUR-certified foam, organic cotton, and North American spruce for superior comfort, ample breathability, and superb durability. It's designed to provide great support while maximizing the lifespan of your mattress.
The brand recommends pairing its foundation with a standard (non-platform) bed frame or Saatva's Universal Bed Frame (sold separately). You can use it with any memory foam, latex, or hybrid mattress. Just like its mattresses, the Saatva Foundation includes a 1-year trial, a lifetime warranty, and free White Glove Delivery.
Saatva Foundation: Prices and extras
- Discount usually applies when paired with a Saatva mattress
- Comes with a one-year trial and a lifetime warranty
- Also includes free in-room setup and old foundation removal
The Saatva Foundation is available in nine sizes and two heights (4.75" and 8.75") to suit all mattresses. Here is a breakdown of the MSRP for all bed sizes:
- Twin: $225
- Twin XL: $225
- Full: $305
- Queen: $355
- Split Queen: $375
- King: $450
- Split King: $450
- Cal King: $450

While it may not qualify for an individual discount, you can get up to 30% off the Saatva Foundation when you pair it with a mattress. No matter what, you'll still receive Saatva's industry-leading benefits: a lifetime warranty and a 365-night sleep trial. The brand also offers complimentary White Glove Delivery service, which means you need not worry about setting it up or getting rid of an old foundation.
Note that the prices are different for the 2" Saatva Bunkie Board, which starts from $175 for a twin. Go with this low-profile option if you have a platform bed, a bunk bed, a loft bed, or a daybed.
Saatva Foundation: Design and materials
- Available in a 4.75" or 8.75" profile — there's also a 2" bunkie board
- Rounded corners allow it to seamlessly blend in with mattresses
- Made to order in the USA using high-quality materials
A mattress foundation is made of wooden slats for support, as opposed to coils in traditional box springs. The Saatva Foundation uses 3" wide slats, the number of which differs according to the size. The twin, twin XL and full sizes have five evenly spaced slats while queen, king and California king sizes have seven slats.
The 8.75" Saatva Foundation works well for low profile mattresses (11.5" or lower); the 4.75" height is a better option for standard profile beds (12" or above). Either way, the rounded corners help blend the foundation in with the mattress for a streamlined look.
Meanwhile, the 2" Saatva Bunkie Board goes well with slatted platform beds, bunk beds, loft beds, and daybeds. You can also place the bunkie board under dual-sided mattresses like the Saatva Zenhaven or heavier foam mattresses for additional support without the extra height.
The Saatva Foundation and Bunkie Bed are crafted to order in the USA using high-grade materials including CertiPUR-US foam, organic cotton, and North American spruce for support, breathability, and durability.
Saatva Foundation: Comfort and support
- Provides a sturdy base for all types of mattresses
- Wood and foam construction absorbs motion and noise
- Brings mattresses to a manageable height for getting up and down
Traditional box springs may become unsupportive or noisy over time so if a stable surface for an uninterrupted night's sleep is your priority, the Saatva Foundation is your best pick. It's designed to fit any mattress type, providing optimum support while ensuring proper spinal alignment and even weight distribution. It'll also elevate your mattress to a comfortable height and prolong its lifespan.
Couples who share a bed with a restless partner can also benefit from the Saatva Foundation as the wood and foam design will help absorb motion and noise. Those who like a firmer sleep surface will also get on with the Saatva Foundation thanks to the support from the wood slats.
As of January 2025, the Saatva Foundation has a 4.9-star rating out of 5 based on nearly 150 reviews. Dozens of satisfied customers suggest the Saatva Foundation delivers restful sleep and enhances the performance of their beds by reducing noise, adding support, and bringing their mattresses to a manageable height.
Should you buy the Saatva Foundation?
Buy the Saatva Foundation if...
✅ You need a firm mattress: If you're someone who prefers a firmer feel to your bed, this additional support will be ideal.
✅ You share a bed: A mattress foundation will help absorb the motion to an extent, perfect if you're prone to toss and turn all night or have a restless partner.
✅ You want to prolong the lifespan of your bed: Made from premium materials, the Saatva Foundation is crafted to be a sturdy base for your bed and will reduce wear and tear due to regular use.
Don't buy the Saatva Foundation if...
❌ You want a soft bed: If a softer bed is what you're after, this foundation may not be the right choice as it'll create a firmer surface. Opt for one of our best mattress toppers instead.
❌ You want something easy to move around: You will still need a standard bed frame for your mattress. An additional component could make it hard to move around if you're one to change your space often.
❌ You don't need a new mattress: You'll generally only be able to save on a Saatva Foundation when you pair it with a new mattress from the brand.
