A steady base for your bed
SEALY® Boxspring — High Profile 9″
The SEALY® Boxspring — High Profile 9″ is the classic, full-height foundation — a solid wood frame paired with the SealySupport™ steel performance grid for a dependable, even base under your mattress. At a full 9″ (22.9 cm), it suits lower bed frames and lifts the mattress to a comfortable, everyday height. Built in Canada and backed by a 10-year warranty.
Key Features
SealySupport™ steel grid
A one-piece steel performance grid over a solid wood frame — a shock-absorbing support system that also helps minimize motion transfer between sleep partners.
Classic 9″ high profile
A full-height base that pairs with lower bed frames and sets the mattress at a comfortable, everyday height.
Solid wood frame
A sturdy Spruce/Pine/Fir frame engineered for even, full-surface support, with corner guards that protect the edges.
Non-Skid Top · vented
A non-quilted stretch-knit fabric that grips the mattress and helps keep it in place; the vented build lets the foundation breathe.
Made in Canada
Built in Canada from responsibly sourced lumber — Sealy's foundation suppliers are SFI, FSC and CSA certified.
Benefits
Steady, even support — the SealySupport™ steel grid over a solid wood frame holds your mattress flat and fully supported, corner to corner.
Helps your mattress last — a stable base supports the mattress to help prevent sagging and bowing over time, so it keeps performing.
The right everyday height — at 9″, it works with lower bed frames and brings the mattress up to a comfortable height to sit on and rise from.
Stays put, breathes well — the Non-Skid Top grips the mattress while the vented frame keeps the foundation airy.
What’s Inside
How the foundation is built, and how to keep it.
Support core — SealySupport™ steel grid over solid wood
A one-piece steel performance grid sits over a solid Spruce/Pine/Fir frame — a shock-absorbing support system that carries the mattress evenly and helps minimize motion transfer between sleep partners. Corner guards protect the edges, and the lumber is responsibly sourced from SFI, FSC and CSA certified suppliers.
Cover — Non-Skid Top
A non-quilted stretch-knit fabric tops the foundation and grips the mattress to help keep it in place. The build is vented so air can move through; fabric may vary.
Care
Spot clean only. The cover is not removable; vacuum the foundation and air it out periodically to keep it fresh.

Getting ready for delivery
- Measure first. Check doorways, corners and stairwells, especially for a King.
- Clear the path. Move pictures, decor and anything you could trip on from halls and stairs.
- Protect floors and steps. Cover delicate floors. In winter, salt the outside steps.
- Tight fit? If the bed has to bend or squeeze through, we may ask you to sign a damage waiver.
Setup upgrades and old mattress removal
- In-room delivery. We carry the bed into the room you choose.
- White-glove setup. We carry it to your room, unbox and assemble it, and take your old mattress to the curb if you need. The packaging stays with you, folded and flattened.
- Old mattress removal on its own. Available in select areas for a fee. Ask our team before you order.
