- Is this mattress good for side sleepers?
- It is firm, so most side sleepers will find it too hard on shoulders and hips. Side sleepers usually do better on a medium or plush mattress.
- What is the difference between the Classic and the Elite LTD?
- The Clarks Hill Elite LTD is the 13-inch firm all-foam model in Serta's Classic line. Check the exact model name on the law tag, since Serta uses similar names across retailers.
- Does it need a box spring?
- A firm foam mattress like this works on a platform bed or a slatted frame with close slats. A box spring adds height but is not required.
- How thick is it and will sheets fit?
- It is 13 inches thick, so use deep-pocket sheets rated for 13 to 15 inches. Standard sheets may pull off the corners.
- Is $934 a good price?
- It is the only new price we track, $934 at The Home Depot as of November 8, 2026. Without other stores listing it, compare against similar firm California King foam mattresses before buying.
- Is it hot to sleep on?
- All-foam mattresses without cooling layers tend to trap heat. Hot sleepers should look for a hybrid with coils or a breathable cover.
- Where is the Serta Classic Clarks Hill Elite LTD 13" Firm Mattress cheapest?
- At The Home Depot, for $934.00, as of our latest check.
