Truly luxurious inside and out.

- Tom H., Portland, OR

Mattress World Northwest went above and beyond the call of duty to ensure I had a bed that would give me plenty of back support. After testing out about 15 different models, I kept coming back to the Coningsby. Everything about this mattress was perfect for my needs. Firm, but not overly hard, a silk covering that feels cool all the time, and strong innerspring coils for total body support (I weigh 295 pounds so this was important!) It was time that I invested in my health, and the Stearns & Foster beds are truly luxurious inside and out.

Like sleeping in a 5-star hotel every night.

- Katrina E., Portland, OR

My last Stearns & Foster mattress served me well for nearly 11 years, so I couldn’t help but see what new products they had in store. It was a no brainer after lying down on the Coningsby Luxury Firm, and the price point couldn’t be beat! I‘ve only had the bed about 6 weeks, but totally LOVE it! It’s like sleeping in a 5-star hotel every night. My hot flashes don’t bother me as much since the mattress quilting stays cool, and I now sleep soundly for a solid eight hours.
