  • The Mattress Upgrade That Turned My Son’s Dorm Bed into a Floating Oasis
Color: White Size: Twin XL Style: 6 Inch Pattern Name: Foam Mattress
Ladies and gentlemen, let me introduce you to the NapQueen 6 Inch Twin-XL Size Mattress – a piece of sleep technology so transformative that it might as well come with a magic wand. My son, who previously endured the classic “dorm room paper-thin mattress experience,” decided enough was enough. Enter the NapQueen mattress, and suddenly, his bed went from resembling a stack of cardboard to feeling like he’s drifting on a fluffy cloud. It’s like moving from a wooden bench to a king-sized throne, and let me tell you, he’s ruling the realm of comfort with absolute authority now. First off, the setup was a breeze. It came rolled up in a box, and I half-expected it to unfold into a magical sleep paradise with confetti and fanfare. Instead, it expanded into a mattress so plush, it could probably double as a trampoline if it weren’t for the cooling gel memory foam that ensures he doesn’t wake up in a puddle of his own sweat. It’s like the mattress fairy decided to grant him the best sleep of his life – just without the sparkles and fairy dust. Since adding this mattress on top of his paper-thin dorm bed, my son reports that his bed now feels like it’s been dipped in cloud fluff and infused with dreams of uninterrupted slumber. He says it’s so comfortable, he occasionally considers asking it for advice on life’s big questions or if it could help with his homework. Five stars for turning a barely-there bed into a sleep sanctuary worthy of royal status, and for ensuring that his dorm room is now the envy of every fellow student who still has to deal with a mattress that feels like it was designed by an evil mattress wizard. ... show more

  • Comfortable cooling memory foam mattress
The NapQueen 6-inch Elizabeth cooling gel memory foam mattress is excellent for comfort and support. Sleep quality noticeably improved, and the cooling foam helps prevent overheating and night sweats. It’s firm enough for stability yet soft enough for comfort, making it a good balance for everyday use. Verdict: A great budget-friendly memory foam mattress—comfortable, cool, and supportive. ... show more

  • Quality changed for the worse.
Color: White Size: Twin XL Style: 6 Inch Pattern Name: Foam Mattress
I bought this mattress in July 2024 and it was perfect for my toddlers floor bed. Fit flawlessly, good quality, etc. I bought another August 2025 for my other floor bed and it’s not nearly the same quality. Much thinner, doesn’t fit the bed frame (same frame), and way lower quality. Not cool.

  • Poor Quality
Color: White Size: Twin XL Style: 6 Inch Pattern Name: Foam Mattress
Does not expand to the size you pay for. I brought the 6" mattress, it expanded to 5" at the widest width. The other areas are defected. See photos. It's such an inconvenience to return it. Normally that's exactly what I would do, but I recently had ulnar nerve transposition surgery so the seller got over on me this time, but let my review serve as your warning. ... show more

  • Almost wasn't a keeper.
Color: White Size: Twin XL Style: 6 Inch Pattern Name: Foam Mattress
This package was ripped and taped over when it arrived. It seems that the contents were not damaged, but if it wasn't sorely (pun intended) I would have sent it back without opening, since it is virtually impossible to get it back in the box once you unwrap it. The mattress is not quite the 6" thickness that was chosen, but good enough. The other dimensions are perfect, 38" X80" twin XL. My wife is satisfied with the comfort, and I will be back, if any other problems arise. ... show more

  • Nice bedframe
The bedframe is very sturdy. All parts were, in fact, in the packaging. Parts "S" and "U" I think are the same. For reference these parts were bolts. One set of bolts were shorter than the other set. When laying out all the parts, place bolts on the pics to make sure you're using the correct bolts at the correct stage in assembly! Reading is fundamental! Have 2 people when assembling, makes things much easier. But the frame is quite sturdy. The headboard goes very well with any decor and is well constructed for the price/value. Buy it. It's nice ... show more
