The decision: You're browsing mattresses, toppers, and bed bases and have narrowed it down to two in-a-box chevni gel memory foam spring mattresses. One is listed as the 12"14" Mattress In a Box Gel Memory Foam Pocket Spring Twin Full Queen King Size; the other is the 12" 14" Twin Full Queen King Mattress Gel Memory Foam Hybrid Spring Bed In a Box. The specs look close, so the real question is which cover color and price point fits your bedroom.
Quick verdict: If you want the slightly lower listed price, the Pocket Spring model in Dark Gray makes more sense. If you prefer a Black cover and want a listing that calls out High breathability, the Hybrid Spring model earns the nod at a slightly higher listed price.
| Product | Listed price | Price bar | Highlighted details |
|---|---|---|---|
| 12"14" Mattress In a Box Gel Memory Foam Pocket Spring Twin Full Queen King Size | USD 315.38 | Gel memory foam and pocket springs; Dark Gray cover | |
| 12" 14" Twin Full Queen King Mattress Gel Memory Foam Hybrid Spring Bed In a Box | USD 320.80 | Gel memory foam hybrid springs; Black cover |
Shared ground: Before splitting the differences, note the overlap. Both are chevni mattresses with fabric covers and a department aimed at Kids, Teens, and Adults. Both listings cover the same suite of Twin, Full, Queen, and King sizes. The real separation is in cover color and the small price gap.
Where the Pocket Spring model wins:
- It lists a lower price, with a spread of about USD 5.42 between the two listings.
- The Dark Gray cover fits neutral or gray-toned bedrooms.
- The pocket spring construction is the specific support story behind this in-a-box mattress.
Where the Hybrid Spring model wins:
- Its listed attributes include High breathability, so airflow-minded shoppers get an extra detail to weigh.
- The Black cover gives a darker profile for the bed.
- Given the small price gap, the color plus breathability note can be the deciding factor.
12"14" Mattress In a Box Gel Memory Foam Pocket Spring Twin Full Queen King Size

At USD 315.38, this is the lower-priced listing of the two. It combines gel memory foam with pocket springs for a medium-firm feel, and the cover is Dark Gray. The listing also notes breathable, hypoallergenic, and portable features. Choose it when the gray cover and the modest price saving match your priorities. The trade-off is the shade: if Black is the cover color you want, the other listing is the one that pairs that color with its attributes.
12" 14" Twin Full Queen King Mattress Gel Memory Foam Hybrid Spring Bed In a Box

This chevni hybrid lists at USD 320.80. It blends gel memory foam with hybrid spring support and a medium-firm feel, wrapped in a Black cover. Its listed attributes call out High breathability in addition to the same breathable, hypoallergenic, and portable feature set. Pick it when the darker cover or the high breathability detail is worth the roughly five-dollar price step from the other model. The main limitation is the higher listed price; otherwise, the two are very close in what they promise.
Final choice by use case:
- Choose the 12"14" Mattress In a Box Gel Memory Foam Pocket Spring Twin Full Queen King Size for the lower listed price and Dark Gray cover.
- Choose the 12" 14" Twin Full Queen King Mattress Gel Memory Foam Hybrid Spring Bed In a Box for the Black cover and the listed High breathability attribute.
