Beautyrest Black Series One Extra Firm

Sources & review notes

• Exact model — Beautyrest Black Series One Extra Firm. Checked 2026-08-26. Series One is the entry tier of the current four-series Black collection, which runs to roughly twenty models across Series One, Two, Three, and Four. In 2024 Beautyrest replaced its former B, L, C, and K Line names with these series numbers, and the series are not direct renames of the old classes. Retailers and older reviews still use C-Class, L-Class, and K-Class. Results here apply to this variant only.
• Type — Quilted pocketed-coil innerspring. Checked 2026-08-26. Beautyrest gel memory foam over Triple-Stranded Pocketed Coil Technology, under a cool-to-the-touch quilted cover with Sleep Climate Technology. A separate Black Hybrid Series One is sold alongside it, so check whether the listing you are reading says Hybrid.
• Firmness — Extra firm — 8/10 measured. Checked 2026-08-26. Beautyrest sells this variant as Extra Firm and the independent lab measured 8 of 10, placing it at the firm end of the market. Series One also ships in Firm Pillow Top, Medium, Medium Pillow Top, Plush, and Plush Pillow Top — those feel materially different and none of the results here transfer to them.
• Height — 13.5 inches. Checked 2026-08-26. Consistent across sizes on the tested variant. Height climbs sharply further up the collection — Series Four models run past 17 inches — so sheet and bedding fit is not transferable between series.
• Price — Check current price — $1,349 queen on beautyrest.com. Checked 2026-08-26. The independent reviewer recorded a $1,749–$2,899 range across sizes, above the direct queen price on the checked date. The mattress is also sold through Mattress Firm, Home Depot, Macy’s, and JC Penney, each at their own price, so a single figure is unreliable for this model.
• Trial — 100-night in-home trial. Checked 2026-08-26. That is the term when you buy directly from Beautyrest. Third-party retailers set their own trial lengths and conditions on the same mattress, so the decision window depends on where you buy rather than on what you buy.
• Delivery — Free White Glove delivery, 2–4 weeks. Checked 2026-08-26. Includes in-room setup and free removal of your old mattress on request, provided it is in sanitary condition. Not shipped to Alaska or Hawaii. Quick Ship is available on some sizes and locations, which shortens the wait.
• Returns — Full refund during the 100-night trial. Checked 2026-08-26. Free shipping and returns when bought direct. Retailer return policies differ and may add fees or restocking terms, so read the policy of whichever store you actually buy from.
• Warranty — 10-year limited warranty. Checked 2026-08-26. Shorter than the lifetime terms common among online rivals in this price range. As always, coverage turns on the written indentation threshold and on using proper support — read the terms before treating it as long-term protection.
• Firmness — Extra firm (8/10). Measured data. Genuinely firm, and the measurement agrees with Beautyrest’s own Extra Firm label. Expect to lie on top of this mattress rather than in it, which drives almost every other result below.
• Pressure relief — 6.5 / 10 test-lab rating. Measured data. The weakest measured attribute. A thin gel-foam layer over a firm coil unit does little to cushion the shoulder and hip, which is a deliberate design choice rather than a defect — but it is the wrong choice for pressure-sensitive sleepers.
• Cooling — 8.5 / 10 test-lab rating. Measured data. A real strength. Because you sink very little, far less of the body is enclosed by foam, and the pocketed coil unit moves air freely beneath the quilted cover.
• Motion isolation — 6 / 10 test-lab rating. Measured data. Poor for the price. A firm surface with a shallow comfort layer transmits a partner’s movement rather than absorbing it — the clearest reason for light-sleeping couples to look elsewhere.
• Response / bounce — 9 / 10 ease-of-movement rating. Measured data. Near the top of the scale. There is essentially no contour to climb out of, so changing position takes almost no effort — the flip side of the weak motion isolation.
• Edge support — 9 / 10 test-lab rating. Measured data. Excellent, and the standout number on this mattress. The firm surface barely compresses under a seated load, so the full width stays usable for sleeping and for getting in and out.
