Mattress depth
Mattress thickness: current product depths and bed-height math
Current Tempur-Pedic models in the cited US lineup are 10, 11, 12, or 13 inches thick. Mattress depth is a finished product measurement—not a standard tied to Twin, Full, Queen, or King width and length.
Semrush US · 1,000 searches/mo · KD 22| Label or calculation | Dimensions | What it means |
|---|---|---|
| Current 10-inch example | TEMPUR-Cloud: 10 in (25.4 cm) | Manufacturer-listed finished model height. |
| Current 11-inch example | TEMPUR-Adapt: 11 in (27.9 cm) | Manufacturer-listed finished model height. |
| Current 12-inch examples | TEMPUR-ProAdapt and ProBreeze: 12 in (30.5 cm) | Two models with the same listed depth. |
| Current 13-inch examples | TEMPUR-LuxeAdapt, LuxeBreeze, and ActiveBreeze: 13 in (33 cm) | Three models with the same listed depth. |
| Top-of-mattress geometry | support height + foundation/base + mattress + added layers | A planning sum; compressible layers can change the observed result. |
This guide records current product depths and measurement geometry only. It does not recommend a depth, firmness, sleeper match, therapeutic use, support system, or adjustable-base pairing.
Width and length do not determine thickness
Two mattresses with the same Queen or King top can use different finished depths. Read the model specification and measure the actual vertical edge after the product has reached its stated setup condition.
Total bed height is an addition problem
Measure from the floor to the support surface, then add any foundation or base profile, mattress depth, pad, and topper. Keep each layer separate so a changed component can be recalculated.
Sheet-pocket depth uses the entire covered stack
A fitted sheet must clear the mattress plus any topper and pad it encloses. Compare the measured stack with the sheet maker’s stated pocket construction and finished dimensions.
Measurement method
Start with the product and space you actually have.
- 1
Measure the finished edge. Record the current mattress depth at a representative side.
- 2
Keep layers separate. List the support height, foundation or base, mattress, pad, and topper.
- 3
Add the covered stack. For fitted sheets, total only the layers enclosed by the sheet.
- 4
Read product dimensions. Compare the result with the manufacturer’s stated measurements.
Questions, answered
Frequently asked questions
How thick are current mattresses?
The current manufacturer lineup cited here spans 10 to 13 inches, with model-specific listings at each whole-inch depth.
Does mattress size determine mattress thickness?
No. Twin, Full, Queen, and King name the top width and length; finished depth is a separate model measurement.
How does mattress depth affect fitted sheets?
Add the mattress, topper, and pad layers enclosed by the fitted sheet, then compare that measured stack with the product’s stated pocket depth and construction.
