The MLILY JAMA 5 and JAMA 7 are children’s mattresses with different profiles. The most useful first question is whether the bed frame permits the extra height: the JAMA 5 is approximately 5 inches tall and the JAMA 7 approximately 7 inches tall. Confirm the exact model, dimensions and availability before ordering.
About this comparison: This guide compares published product information and dimensions; it is not a claim that we performed new side-by-side sleep or laboratory tests. Yawnder sells MLILY products. MLILY’s newer JAMA lineup may use different model names and specifications; verify the exact version with the seller.

Who should choose the JAMA 5?
The lower profile is worth considering for a bed with a strict mattress-height limit. Measure the frame’s stated maximum rather than estimating from photos, and make sure the mattress dimensions leave no unsafe gaps around the bed frame. Ask for the exact cover and included accessories before ordering; older and newer JAMA products can differ.
Who should choose the JAMA 7?
The JAMA 7 has a taller foam construction. MLILY describes the model as medium feel and lists a washable cover; check the care label and the precise version you receive. The extra two inches of nominal height do not guarantee a particular feel or lifespan, and the mattress must still meet the bed manufacturer’s requirements.
Will either mattress fit a bunk bed or trundle?
Possibly, but the model name alone cannot establish a safe fit. Read the bed manufacturer’s maximum mattress thickness and required length and width. On the upper bunk, the U.S. Consumer Product Safety Commission requires the top of the guardrail to be at least 5 inches above the top of the mattress. Children younger than six should not use an upper bunk. Follow the bed’s instructions and safety labels, including any stricter limit.
A 7-inch mattress leaves about two fewer inches of guardrail above the mattress than a 5-inch mattress in the same frame. Measure with the mattress actually in place and account for any topper. For a trundle, measure clearance when the bed rolls under the frame. Read our bunk-bed mattress guide.
Age, support and care
MLILY describes the JAMA 7 for children ages 3 and up. It is not an infant or crib mattress. Always follow the age and safety directions for the specific mattress and bed frame. Use a suitable foundation, check the cover’s care label, and ask the seller whether a protector is included with the configuration you are purchasing.
Price, availability and policies
Prices, sizes, colors and inventory can change. The JAMA 5 and JAMA 7 are listed on Yawnder, but listings and manufacturer lineups do not by themselves guarantee current stock.

Frequently asked questions
Is the JAMA 7 always better than the JAMA 5?
No. A thicker mattress may not fit a bed with a low height limit. Choose based on fit, feel, the child’s needs and the exact model available.
Can I use either for a baby?
These are children’s mattresses, not a substitute for an appropriately sized infant crib mattress. Follow the crib and mattress manufacturers’ infant-sleep instructions.
Are JAMA covers washable?
MLILY lists a washable cover for the JAMA 7. Check the care label and verify the cover details for the specific JAMA 5 version before purchase.
Are newer JAMA mattresses the same as the JAMA 5 and 7?
Not necessarily. Model names, heights, layers and availability can change. Ask the seller to confirm the product specifications in writing.
