No, I buy them refurbished. They strip the mattresses and boxsprings down to the wood and wire, disinfect them, then replace the fabric/padding/etc with new materials.

It's essentially no different than newly built. I've been buying these for decades and have never had an issue with bedbugs or any other nastiness.

They are less expensive, but not dramatically so. But I get a quality bed, don't have to deal with mattress shops, and get a little bit of feel-good from helping to employ people who otherwise have difficulty finding work.

And they deliver.
