Kingsdown Twin Xl 3" Foundation

Not available in your region

SKU: 51005556

Kingsdown foundations are meticulously hand assembled using sustainably sourced Canadian Spruce, which is exceptionally durable. Each piece of lumber is not only heat-treated, but kiln-dried, which improves the performance of the wood over time. Each wooden slat is placed more closely together and cut a full inch wider than most manufacturers to provide a sturdier base.

Nice cool sheets

This review was collected as part of a promotion

Sheets keep you cool which was the whole reason I purchased them. They aren't the most comfortable sheets as they be rubbing against ones self but if you want coolness while you sleep than they will do the job.

Nice but not the best

This review was collected as part of a promotion

I like these sheets but don’t love them. Not as soft as I thought they would be especially for the price
