# OSASET King 8-Inch Metal Box Spring

The OSASET King metal box spring is an 8-inch-high mattress foundation with a steel frame, removable fabric cover, and a claimed 3000 lb support capacity. It has no legs and requires a compatible bed frame or platform underneath, so it is not a standalone bed base.

## At a glance

- The 8-inch profile is intended to add mattress height without using a taller foundation.
- The listing describes a steel frame and claims it supports up to 3000 lbs.
- Its cover is described as removable using elastic bands for cleaning.
- The included tools and instructions are intended to simplify assembly.

## Pros

- King sizing and stated dimensions provide a clear starting point for checking fit with a mattress and supporting base.
- A removable cover is a practical feature for cleaning.
- The listing says assembly tools are included, avoiding the need to source separate tools.

## Cons

- It has no legs, so it needs a separate bed frame or platform for support.
- Customer feedback reports conflicting experiences with noise, durability, and stability.

## Before you buy

- The listing presents the height as 8 inches and gives dimensions of 80 x 75 x 8 inches, while its Q&A says a supporting bed frame or platform is required and the product has no legs. Check the actual fit and support arrangement for your bed. The 3000 lb capacity and noise-resistant performance are manufacturer claims, while customer feedback differs on creaking and durability.
- A product description says assembly can be completed in minutes, while its Q&A allows up to 30 minutes. Treat both as estimates rather than a guaranteed setup time.

## A good fit for

- King mattress owners seeking an 8-inch metal foundation to use on a separate bed frame or platform.
- Buyers who prefer a foundation with a removable cover for cleaning.

## Less suited to

- Anyone seeking a complete bed frame or a foundation with legs.
- Buyers who need confirmed quiet operation or long-term durability, given mixed customer reports.

## Customer feedback

Customer feedback is favorable about assembly and fit for some buyers, including reports of easy setup with clear instructions. Experiences are mixed on size, noise, quality, and value, and some customers report early breakage or stability concerns. That variation matters for a foundation advertised with a 3000 lb capacity and a squeak-resistant design, since those are listing claims rather than assurance that every setup will perform the same way.
- Positive themes: Some customers say assembly is easy and instructions are clear.
- Positive themes: Some customers report that the foundation fits their needs, including with adjustable bed frames or in small apartments.
- Negative themes: Some customers report breakage within three months.
- Negative themes: Some customers report metallic creaking or stability concerns.
- Mixed feedback: Customers disagree about whether it stays quiet, fits as expected, and offers satisfactory quality and value.
