Overview
Standing 9 inches tall, the ALDRICH box spring is a metal foundation built for king mattresses, pairing with innerspring, memory foam or latex mattresses per the listing, and rated to 3000 lbs.
A high profile foundation like this is bought to solve two things: bed height, and the sag or squeak of an old box spring. The welded frame and fitted cover are the two features doing that work here.
- 9 inch high-profile foundation
- King size, 3000 lb capacity
- Welded metal slat frame
- Included fitted cover
Who it's for
Fits king bed owners replacing a sagging or noisy foundation, or anyone who wants extra bed height. Not the right pick for a low-profile bed frame or anyone using a platform frame that needs no box spring at all.
Strengths and trade-offs
Drawn from this product's published specifications.
- High 9 inch profile adds bed height
- Welded frame joints aim to cut noise
- Removable cover included for easy cleaning
- 9 inches may be too tall for some frames
- King size only in this listing
- No warranty or steel gauge details given
Performance notes
The frame's poles and supports are welded at both ends, which the listing points to as the fix for the shifting that causes box spring squeaks. Steel slats spread weight across the frame up to the rated 3000 lbs, and the elastic-band cover is meant to keep the mattress from sliding on top of it.
