Is the Prettsun 5 inch twin mattress worth it?

For a bunk bed, trundle, dorm or guest room, yes. At $44.99 at Walmart as of November 4, 2026, it costs less than most twin foam mattresses. For a daily adult bed, a thicker mattress is a better buy.

It is medium-firm. Most sleepers find it supportive for its thickness, but side sleepers over about 150 pounds may want more cushioning.

Does it work on a bunk bed or trundle?

Yes. The 5-inch height is made for low frames, including bunk beds, trundles, daybeds and platform beds. Check your frame's height limit before ordering.

How long does it take to expand?

It ships compressed and usually reaches full height within 24 to 72 hours after unrolling. Some corners may take longer.

Is it fiberglass-free and certified?

Yes. Prettsun states the mattress is fiberglass-free and CertiPUR-US certified, which covers foam emissions and content.

The current $44.99 at Walmart as of November 4, 2026 is already at the low end of its recent range. Watch for back-to-school and holiday sales for further drops.
