The bed is super comfortable we are happy with our purchase of the King Hybrid Premier model! It’s super solid, firm, puffed up and comfortable. I let it sit for the recommended 72 hrs to ensure it was fully fluffed up. For the price, it was an absolute steal compared with other top brands. Highly recommend it.

The plush feel gives you that soft, cloud-like sensation when you lie down, but it doesn’t sink too much. The hybrid design combines supportive coils with gel memory foam, so you get the best of both worlds — contouring comfort and stable support.

Get Answers to Commonly Asked Questions About King Size Mattresses
A standard king-size mattress measures 76 inches wide by 80 inches long. It is one of the widest standard mattress sizes available and offers the most personal space for couples, families, co-sleeping with children, or pets.
Two standard twin mattresses do not create a true king-size bed. While they match in width, they fall 6 inches short in length.
1. Twin mattress: 38" x 74"
2. Twin XL mattress: 38" x 80"
3. King mattress: 76" x 80"
To form a king-size bed with two separate mattresses, you need to use Twin XL mattresses. This arrangement is referred to as a Split King.
The Split King is a popular choice for couples because it allows each person to customize their side of the bed with different firmness levels or an adjustable base, all without disturbing their partner.
👉Standard King (Eastern King)
Size: 76" wide x 80" long
Minimum room size: 12' x 12'
Best for: Couples, Families who co-sleep, Master bedrooms.
👉California King (Western King)
Size: 72" wide x 84" long
Minimum room size: 11' x 13'
Best for: Tall individuals (over 6'5") who need extra legroom.
A split king mattress is made up of two separate Twin XL mattresses, each measuring 38 inches by 80 inches, positioned side by side. This arrangement provides the same overall dimensions as a standard king-size bed. It is specifically designed for couples who have different comfort preferences, allowing them to enjoy two independent sleep spaces within one shared bed.
The dimensions of RV King mattresses are not standardized like residential King mattresses. They are specifically designed to fit the unique floor plans of various RVs, resulting in a few common variations.
1. RV King: 72" x 80" – This is the most common RV King size, also known as the "RV Eastern King." It matches the length of a residential King but is 4 inches narrower.
2. RV Short King: 72" x 75" – This popular alternative is 5 inches shorter than a standard residential King, making it suitable for RVs with space constraints.
3. RV California King: 72" x 84" – This longer option is designed for larger RVs that can accommodate the extra length, matching the length of a residential California King.
Yes, a 10-foot U-Haul truck can easily fit any standard king-size mattress, including a California king.
10' U-Haul Cargo:
Length: 9' 11" (119")
Width: 6' 4" (76")
Height: 6' 2" (74")
The width of the truck's interior (76 inches) exactly matches that of a king mattress. While a Cal King mattress is 4 inches longer than a standard king, the truck's interior is 119 inches long, so there is still more than 2 feet of extra space.
Regardless of which king mattress you choose, even a thick 14" pillow-top mattress will take up less than a quarter of the truck's 74-inch interior height, leaving more than 5 feet of space above it for boxes and furniture.
BedStory king-size mattresses are compressed, rolled, and shipped in a compact box small enough to carry and fit through doorways.
Expansion occurs in stages :
4 to 6 hours – Initial expansion, visible shape forming
24 hours – Significant expansion, can sleep on it
48 to 72 hours – Full expansion to the intended shape and firmness
It's recommended to wait 1-3 days before use.
While you can sleep on it immediately after unboxing, the mattress requires 48-72 hours to reach its full shape and firmness. For optimal comfort, wait at least 24 hours.
