Beautyrest World Class Level Four: exact plans, heights and seller limits
This is a model-specific guide to Beautyrest World Class Level Four, not a comfort test. Keep it separate from the World Class Level Three quilted mattress and from either World Class Hybrid family. The current maker pages identify four quilted plans, six standard sizes and four plan-specific ProductGroups with six size-coded children each.
Compare the four exact plan labels
The exact plan pages list Firm Pillow Top, Medium, Plush and Plush Pillow Top. Firm Pillow Top is the only name that enters the finder’s broad Firm choice; Medium enters the Medium choice. Plain Plush and Plush Pillow Top are not the separate Plush Soft, Supportive Plush or Medium Firm choices. There is no shared numeric firmness score.
Beautyrest’s plan pages attach different broad guidance: Firm Pillow Top for back and stomach sleepers, Medium for all sleepers, and the two Plush plans for side sleepers. This is a maker description, not a personal outcome. Compare the plan and maker guidance in the full assessment.

Six standard sizes; no split size shown
Each exact plan page lists Twin, Twin XL, Full, Queen, King and Cal King. Neither Split King nor Split California King appears. Verify that the seller’s offer has the selected feel and size together; a maker SKU, common size name or photo does not identify an outside retailer package.
Height depends on the feel plan
The manufacturer’s quilted dimensions table lists Medium at 15 inches, Plush at 15.25 inches, and both Pillow Top plans at 16.25 inches for each of the six sizes. These are mattress-only product dimensions—not full bed height, frame clearance or stairwell clearance. Do not round the source values merely because the finder accepts half-inch steps.
Firm Pillow Top under a 16.5-inch ceiling
A 16.5-inch ceiling includes the exact 16.25-inch Firm Pillow Top profile when the Firm plan is selected; it does not prove the base, bedding or room clearance will fit.

Firm Pillow Top with a 16-inch maximum
A 16-inch ceiling excludes the exact 16.25-inch Firm Pillow Top plan, even though the same family’s Medium and Plush profiles are shorter.
For a separate Firm Queen under this ceiling, BeautySleep by Beautyrest Dream Weaver lists an 11.5-inch Firm plan; it is not a World Class option or a complete-bed height.

Medium at a 15-inch minimum
The maker lists the Medium profile as 15 inches, so a 15-inch minimum is within the selected Medium plan's documented range.

Medium below a 15.5-inch minimum
A 15.5-inch minimum excludes the 15-inch Medium plan; the taller pillow-top plans are different feel plans, not a reason to call Medium taller.
If a 15.5-inch minimum is essential, the separate Purple RejuvenatePlus page lists a 15.5-inch Medium Queen plan. That is a different model, not a taller configuration of World Class Level Four.

Foundation and direct-site terms
Beautyrest says a box spring is not required, but a sturdy, stable support surface is. Its adjustable-base FAQ limits compatibility guidance to Beautyrest-branded bases the maker has tested with its mattresses; this is not universal third-party or split-system approval. Check both base and mattress instructions.
The plan pages display a 100-night in-home trial and 10-Year Limited Warranty headline. The free return pickup described by the maker applies to eligible direct-site orders under the actual policy, not automatically to an outside seller. Confirm the order-date terms and law-label Warranty Code.
The 100-night direct scenario
For an eligible maker-direct order, the published 100-night trial reaches a 100-night minimum and the current direct policy describes no pickup charge; that does not establish terms for another seller.

How to read the source records
The main family page’s ProductGroup contains 24 children named by size. Separate exact Firm Pillow Top, Medium, Plush and Plush Pillow Top pages each expose a distinct six-size group, so the SKU/GTIN set for each named plan is retained without using row order to assign a feel. Those maker codes are not ASINs. The official staged photo in the review belongs to the Firm Pillow Top page and does not depict every selector.
Beautyrest describes this as a quilted innerspring. Its separate Hybrid page uses a smooth surface and a different foam arrangement. The brand’s “cool-to-the-touch,” pressure-relief and motion-separation descriptions remain design claims, not independent measurements or a prediction of comfort.
