Quick Answer: The Saatva Solaire is a $4,264 (sale; $4,789 regular) air-chamber mattress with 50 firmness settings per side, adjustable from an included remote — it is not an adjustable base and doesn’t ship with one, per Saatva’s own product page. It carries a 365-night home trial and a lifetime warranty with full coverage for the first 3 years. If you want the mattress to also raise and lower at the head and foot, Saatva sells its separate Adjustable Base Plus as an add-on — the two products are commonly confused because they share a brand, a remote-control interface, and a checkout page, not because one includes the other.
“Saatva Solaire” shows up in a lot of searches on this site’s exact topic — adjustable beds — which makes sense, since the name sounds like it could be a base, and Saatva’s own Adjustable Base Plus is already one of our top picks. It isn’t. Here’s what the Solaire actually does, what it costs, and the one real reason the confusion exists in the first place.
What the Solaire actually adjusts
The Solaire is a 13-inch hybrid mattress — organic cotton cover, cooling gel-infused memory foam, and a 5-zone natural latex layer, per Saatva’s own 2026 product materials — built around dual air chambers instead of a fixed foam or coil structure. Each side of the mattress (Queen and larger) has its own chamber and its own remote, and the firmness runs across 50 settings per side, measured in millimeters of mercury (mmHg) and displayed on the remote in real time. Saatva also buckets that range into Soft (settings 3-4 of 10), Medium (5-6), and Firm (7-8) for shoppers who’d rather not think in mmHg. None of that changes the mattress’s shape — it stays flat. There’s no motor, no incline, no head or foot articulation anywhere in the product.
What it doesn’t do — and the base it’s built to pair with
A base in this category means something specific: a motorized frame that raises and lowers the head and foot, usually with presets like zero-gravity or anti-snore. The Solaire has none of that built in. Per Saatva’s own product page, the Solaire can sit on a flat foundation, a box spring, a platform bed frame, or — if you want incline on top of the firmness adjustment — Saatva’s own Adjustable Base Plus, the $1,374 sale / $1,599 regular (Queen) base this site already reviews in depth, including its 25-year warranty and the massage-spec correction we made after checking Saatva’s current listing directly. Saatva sells the two as a bundle with a modest discount, but the base is always an optional add-on, never included.
| Saatva Solaire | Saatva Adjustable Base Plus | Sleep Number FlexFit (any tier) | |
|---|---|---|---|
| What it is | Mattress | Base | Base |
| What it adjusts | Firmness (50 settings/side) | Position (incline, massage) | Position (incline, massage on FlexFit 3) |
| Price (as shown) | $4,264 sale / $4,789 regular | $1,374 sale / $1,599 regular (Queen) | $999–$1,999 (Queen, by tier) |
| Sold bundled? | Base is optional add-on | Mattress is optional add-on | Marketed as one "smart bed" system |
| Trial | 365 nights | No base trial (per Saatva's terms) | Base excluded from 100-night trial |
Saatva Adjustable Base Plus
- Head-and-foot articulation with zero-gravity and anti-snore presets — the incline the Solaire itself doesn't have.
- Pairs with the Solaire for a bundle discount, or works under most other mattresses Saatva sells.
- Split King and Split Cal King versions exist, but the Solaire's Upper-Flex Queen/King sizes only pair with the Upper-Flex King base — check your size match before ordering either piece separately.
Why the confusion exists
Sleep Number built its reputation on bundling the two ideas — a firmness-adjustable mattress (SleepIQ) and a position-adjustable base (FlexFit) — marketed and sold together as one “smart bed.” Saatva’s Solaire does the firmness half of that same idea, with a comparable remote-and-settings interface, but Saatva doesn’t default-bundle it with a base the way Sleep Number does — the Adjustable Base Plus stays a separate line item even when discounted together. If you came looking for “the Saatva version of a Sleep Number bed,” the honest answer is: you need to buy both pieces, and only one of them is a base.
Who should buy which
- Want firmness control, don’t care about incline: the Solaire on its own, on any flat surface you already own.
- Want incline, massage, and presets, don’t care about firmness settings: the Saatva Adjustable Base Plus under whatever mattress you already have.
- Want both: buy them together for Saatva’s bundle discount, and double-check the Upper-Flex sizing match above before you do.
- Want one bundled “smart bed” product instead of assembling two separately-priced pieces: Sleep Number’s FlexFit lineup is built around that exact use case, at a lower combined price than the Solaire alone.
The bottom line
The Saatva Solaire is a premium firmness-adjustable mattress, not an adjustable bed — a genuinely easy mix-up given the shared brand and the Adjustable Base Plus already sitting one click away on Saatva’s own site.
