Quick Answer: Mattress Firm sells adjustable bases in-store and online — house-brand Sleepy’s Signature/Deluxe/Elite and Mattress Firm 900 bases from about $600 to $1,199.99, and premium Tempur-Pedic TEMPUR-Ergo bases from about $1,499 to $2,599 (Queen, before sale pricing). The catch most bundle shoppers miss: Mattress Firm backs its mattresses with a 120-night sleep trial, but adjustable bases are excluded from that trial and sold final sale — with the TEMPUR-ActiveBreeze Smart Bed base as the one notable exception multiple return-policy guides flag as still covered.
Mattress Firm is the largest mattress retailer in the country, and its stores and site treat adjustable bases as a routine add-on to almost every mattress purchase — often bundled in as a “free base with qualifying mattress” promotion. That bundle framing is exactly why the return-policy gap catches people off guard: the mattress feels fully protected by the trial, so shoppers assume the base that shipped alongside it is too.
What Mattress Firm actually sells
| Base | Queen price (approx.) | Notable feature |
|---|---|---|
| Mattress Firm 900 Adjustable Base | ~$600 on sale | Entry-tier house base, frequently the "free with bundle" model |
| Sleepy's Signature Adjustable Base | ~$749.99 | Independent head/foot incline, Mattress Firm's own Sleepy's line |
| Sleepy's Deluxe Adjustable Base | ~$999.99 | Adds massage and additional presets over Signature |
| Sleepy's Elite Adjustable Base | ~$1,199.99 | Top house-brand tier, most preset and massage options |
| Tempur-Pedic TEMPUR-Ergo 3.0 | ~$1,499 | Entry Tempur-Pedic base, fine-grained incline control |
| Tempur-Pedic TEMPUR-Ergo Smart | ~$1,899 | Adds app control and sleep-tracking integration |
| Tempur-Pedic TEMPUR-Ergo ProSmart | ~$2,399 | Top Tempur-Pedic tier, most motors and zones |
Every one of these bases can also show up discounted or “free” as part of a mattress bundle promotion, which is standard practice across Mattress Firm’s sale calendar — see our best adjustable bed deals guide for how to tell a genuine bundle discount from inflated “regular” pricing. The bundle framing is also exactly where the return-policy nuance below matters most.
Tempur-Pedic TEMPUR-Ergo Adjustable Base
- Engineered and tuned specifically for Tempur-Pedic mattress firmness and support layers, the same pairing logic covered in our best mattress for an adjustable bed picks.
- Smart and ProSmart tiers add app control, additional massage zones, and more incline presets over the base 3.0 tier.

The return policy gap most bundle shoppers miss
Mattress Firm’s headline trial is generous on paper: 120 nights from delivery to decide whether a mattress works, with a required minimum adjustment period before you can start a return or exchange. That trial is real, and it applies to the mattress.
It does not apply to the adjustable base. Per Mattress Firm’s own return-policy guidance, adjustable bases are excluded from the sleep trial and sold as final sale — the stated reasoning is the mechanical complexity and sanitation logistics of taking back a used, previously-installed base, the same practical objection furniture retailers raise industry-wide. The one documented exception across current return-policy summaries is the TEMPUR-ActiveBreeze Smart Bed’s adjustable base, which is flagged as remaining eligible where standard bases are not — confirm that exception applies to your specific model before assuming it does.
Here’s the part that actually catches bundle buyers: if you bought a mattress-and-base bundle and decide to return the mattress within the trial window, the adjustable base is yours to keep. It isn’t clawed back, and it isn’t credited toward your refund either way — the base was never a return line item in the transaction, so a mattress return simply doesn’t touch it. That’s a different mechanic than Ashley Furniture’s explicit no-return rule on the base itself, and different again from Costco’s open-ended satisfaction guarantee or Walmart’s 90-day window on directly-sold items — Mattress Firm’s base sits outside the return conversation entirely, in either direction.
Who buying at Mattress Firm actually makes sense for
Mattress Firm’s real advantage is selection and bundling: house-brand bases at multiple price tiers, premium Tempur-Pedic options, and frequent “free base with mattress” promotions that can make the base itself effectively free rather than merely discounted. Its stores also offer in-person testing and financing options that pure online brands don’t match, similar to the showroom experience covered in our Ashley Furniture guide.
Where it falls short is any expectation of flexibility on the base after delivery. If there’s a real chance you’ll want to swap models, downsize, or return the base outright, that safety net doesn’t exist here — the mattress trial won’t help, and the base is final sale from delivery day regardless of bundle terms. For that flexibility, Amazon-sold brands like Sven & Son or Lucid carry standard e-commerce return windows that Mattress Firm’s in-store bundle model doesn’t offer on the base itself.
The bottom line
Mattress Firm sells a full range of adjustable bases, from a roughly $600 entry-tier house base up to a roughly $2,399 premium Tempur-Pedic ProSmart model, frequently bundled free or discounted with a qualifying mattress. The nuance worth knowing before you buy: the 120-night mattress trial doesn’t extend to the base, which is final sale in nearly every case, and returning a bundled mattress doesn’t refund or claw back the base either — you simply keep it.
