No Pressure

Dave Reavis was great. From the moment I stepped into the Lawton store, I didn't feel hassled or pressured. He stepped back and let us look while standing by to answer any questions & provide information. It made us want to stay and look around the store. He was very knowledgeable! Delivery was fast and Tyrone & Cal were the nicest guys! I felt safe and taken care of when they set up my mattress. They were so friendly & accommodating!! I definitely recommend the staff I dealt with!

THE Place to Buy

Mattress King is THE place to buy your next mattress. The Norman store sales person, Blayne, was amazing. He was very informative and answered all our questions, and did not pressure us into any decision. Delivery guys just dropped off the mattress we bought yesterday. They actually took it to the bedroom, took the plastic cover off, put it on the frame all in about five minutes. We are very impressed by their website and its maneuverability, the nice showroom, friendly staff, next day delivery, and the whole experience was fun and very pleasant. Highly recommend Mattress King.

Frequently Asked Questions

Should I use a protector even with a mattress that’s easy to clean?

Yes. Waterproof protectors safeguard your mattress from sweat, spills, and allergens—extending mattress lifespan and preserving warranty protection. Even mattresses advertised as “easy to clean” benefit from added protection between use and cleaning.

What’s the difference between a full encasement protector and a fitted protector?

A fitted protector covers only the sleep surface and sides of a mattress, while a 360° encasement fully encloses all sides and often the underside. Encasements offer maximum protection against bed bugs, allergens, and spills.

Are these sheets and protectors hypoallergenic and safe for sensitive skin?

Yes. All products are made with OEKO‑TEX® certified materials or equivalent standards. Microfiber and performance jersey are naturally resistant to allergens like dust mites and mold, offering a cleaner sleep environment.

What type of sheets are recommended for a split adjustable bed in King size?

For a split adjustable bed in King size, which typically consists of two Twin XL mattresses, the ideal choice is a set of Split King sheets. These sheets include two Twin XL fitted sheets to accommodate the independent movement of each side of the adjustable bed, along with one King size flat sheet for complete coverage. Additionally, consider a Split King mattress protector set, comprising two Twin XL mattress protectors, to ensure complete protection and comfort for your adjustable bed setup.

Do your sheets have deep pockets suitable for thicker mattresses?

Yes, our bedding collection is designed to accommodate a variety of mattress thicknesses. Our Performance Jersey Sheets can fit mattresses up to 16 inches thick, while our Soft Washed Microfiber Sheets are suitable for mattresses up to 16 inches in thickness. Additionally, all our mattress protectors are compatible with mattresses up to 22 inches thick. An added feature of our bedding is the all-around elastic band, ensuring a snug and secure fit on your mattress, not just at the corners.

Do keep in mind the average height of a mattress is 14.5" thick.

What is included in your sheet sets?

Our sheet sets are tailored to fit various bed sizes, ensuring a complete bedding solution. For King, Queen, Full, and Split King sizes, each set includes a fitted sheet, a flat sheet, and two pillowcases. Twin and Twin XL sets come with one pillowcase each. The pillowcases are sized accordingly: King sets have King-sized pillowcases, Queen sets have Queen-sized pillowcases, and Full, Twin, and Twin XL sets include standard-sized pillowcases. The Split King set uniquely features two Twin XL fitted sheets, one King flat sheet, and two King pillowcases.

What is the difference between Twin and Twin XL?

The primary difference between Twin and Twin XL mattresses lies in their length. A standard Twin mattress measures 38 inches in width and 75 inches in length. In contrast, a Twin XL mattress has the same width of 38 inches but offers an additional 5 inches in length, totaling 80 inches. This extra length in the Twin XL makes it a suitable choice for taller individuals or for use in college dorm rooms, where extra legroom can be particularly beneficial. Both sizes are often used in smaller bedrooms, guest rooms, or for children's beds, but the Twin XL's extra length can provide more comfort for growing teens and adults.

How often should I wash sheets and protectors, and what care methods prevent premature wear?

Experts recommend washing sheets and protectors at least every week—or right after any spill or allergen exposure. Use cold or warm water with gentle detergents and avoid bleach or fabric softeners. Keep protectors breathable by washing on cold and tumble drying on low.
