There was a problem filtering reviews right now. Please try again later.
The fibers that they make the protective covering out of shed into tiny airborne fibers that you then breathe in they are similar to fiber glass. They get embedded in your skin causing itching and irritation and also when breathed in caused breathing issues.
My husband and myself both started having horrid allergy issues and my husband ended up even having sinus surgery. Turns out our issues are from breathing in these tiny fibers! Very upsetting. PLEASE PLEASE DO NOT BUY!!!! It took us a year to finally figure out what was causing. I know have damage to my lungs from breathing in fiber glass . There should definitly be a law suit banning these as hazardous.
Here are some factors that coincide with my experience. With my Garmond health monitor, I could see a distinct positive difference in my deep sleep cycle between the previous mattress and this Zinus Sleep Master. I used to fall asleep with books, magazines, remote control on the bed next to me and wake up with them on the floor. Now, they stay right where I left them. I may roll over once or twice but I usually wake up in the same position I fell asleep in and when I wake up, I'm awake! It's almost scary to realize how much of my life went by without this kind of rest.
I did read a ton of comments and the ones that cause most concern I'll compare. First, the packaging was fine. The box is big and bulky but I could carry it up 2 flights of stairs without rest or the need for help. The mattress comes vacuum sealed in a thick plastic wrap. Be careful slicing it open as it's tight on the mattress and you can accidentally cut the removable (and washable) zippered wrap or even into the mattress itself. Regarding the odor that people have noted in other comments. There was a factory/chemical/plastic smell. I'd have to say something closer or comparable to a very light 'new car' smell. Like anything new I wear or sleep under, I washed the thin zippered wrap by itself and dried it once. I've always put a couple dryer sheets on a mattress when I change sheets and did so again with the Zinus mattress. There was no chemical smell after washing the wrap and I'm actually in bed now laying on it while writing this review and there's no smell at all.
There was no mold anywhere to be seen. It's unfortunate that people experienced it and I'm not sure if it's a factory issue or a storage issue. Both mattresses came vacuum sealed in heavy plastic - heavy enough to keep the mattress compressed until it was removed from the box AND cut open. I didn't see it mentioned whether or not the mattress seal was broken or the box it came in had any damage. I'd be turned off as well if I saw that kind of mold and wouldn't buy again but having slept on it - It's worth returning for a new one in my opinion.
It did take several hours to uncompress. No more than 24 hours for the 4" and 8" sizes but we both slept on them the same evening and experienced an incredible sleep.
I did purchase two collapsible smart frames (another great purchase I'll have to review later). There's literally no need for a box spring in my setup as the smart frames are high and built to use bins underneath for storage. As is, they would replace your current mattress and sit on top of your current box spring.
My daughter had a fruit punch Gatorade (red) that was not sealed all the way in her soccer bag. It leaked into the center of the mattress about a month ago. To clean, we used a little detergent and warm water to saturate the spot and pressed a towel down to absorb it. Repeated until there was no red coming up but there is a noticeable red stain (as there would be on any mattress I'm sure). What made it easy to absorb is that you can push down into the mattress without air or spring coils so saturating the spot with clean water and detergent really got the bulk Gatorade out.
In the future, I would get the 12" for myself (because I enjoy a high bed) and the 8" can go to the guest room. I'll be getting another 4" full size for the pull out sofa mattress and I'll get my daughter a 4" twin when she goes off to college.

Juntos de nuevo. Cuando te dicen que no escatimes en un colchón no podría estar más de acuerdo, a fin de cuentas vas a pasar un tercio de tu vida ahí, y quién sabe, con suerte quizá más....guiño guiño. Después de todo, despues de dormir, en un colchón puedes hacer una de laws mejores cosas en la vida, es decir...comer en la cama.
Si ustedes, como yo, habían estado presos de los colchones de resorte porque pensaban que no podián costear un colchón de memory foam, permítanme comentarles que estabamos en un error. Un error enorme pero en serio.
El precio de este colchón parece ser demasiado bueno como para ser cierto, y nosotros como mexicanos estamos programados para desconfiar de ello. Pero *spoiler alert* es cierto! Este colchón es una jo-yi-ta, por este precio muy a duras penas podríamos comprar un colchón de resortes de una merca medio conocida que simplemente no nos encantaría y sólo compraríamos porque "es buen precio, total".
Pues no, con el colchón Zinus obenemos TO-DO, priemero que nada, ustedes recibirán en casita este colchón en una caja bastante compacta y no muy pesada. Acto seguido, por favor lean las muy sencillas instrucciones en español o inglés (por si le están pegando duro al Harmon Hall) en donde se les indicará claramente que deben sacarl el colchónj de la caja, que en ese punto parecerá un delicioso burrito de memory foam, después deben rasgar con las manos el plástico para que el colchón se extienda, después deben quitar el plástico protector y como por arte de magia el colchón comenzará a "inflarse" por si sólo.
Las instrucciones dicne que debe dejarse reposar por entre 24 y 48 hrs para que el colchón obtenga su tamaño debido, sin embargo, en mi caso el tiempo en que esto se logró fue ridiculamente corto, en menos de una hora el Zinus se había extendido en su totalida de altura y estaba esponjoso y bonito.
Otra cosa a recalcar, es que en las indicaciones se coemtna sobre la posibilidad de que tu colchón tenga un olor "extraño" debido al material con el que esta fabricado, que esto es totalmente normal y en breve se le quitará. pero, en mic aso este olor simplemente no existía. Al abrir el colchón se sentía fresco, esponjoso y no tenía nungún olor.
El colchón en cuestión viene ya con una funda, la cual se peude quitar en cualquier momento gracias a su zipper y ser lavada si es deseado, auqneu esta funda no es impermeable, por lo que si queiren esta caracterisitca deben comprar una funda. Aunque los colchones tradicionales no vienen con funda y este sí, por lo que es una gran ventaja
Así llegamos a la pregunta obligada: es comodo? Pero increiblemente comodo!!!!
La capa superior de memory foam se almoda perfectamente a tu peso y fugura, si duermes boca arriba te "sumergiras" sólo lo necesario para estar como y no tneer presión en tu espalda, si duermes de lado la presión en tus hombros y cadera simplemente desaparecerá como magia.
El colchón se amolda a tu cuerpo, no sientes presión, no sientes tu peso, pero no te hundes, el soporte es perfecto. Pensar en volver a un colchón de resortes será obsceno. El futuro es hoy, viejo!
Si han llegado hasta este punto de mi review y no han comprado este colchón, hermanos, no sé qué esperan. En cualqueir otro lugar deberían pagar al menos el doble por este colchón, su manufactura es top, su embalaje es top, es precioso, quizá lloren de felicidad en su primer noche juntos, es razonable.
En cuanto a la logistica de mis amigos de Amazon, precisa, perfecta como siempre. Compré este colchón un viernes a las 23:00 hrs y el domingo a las 9:00 estaba en mi domicilio, gracias a las bondades de Amazon Prime, increible!
Nota: Esta reseña no está pagada por Zinus o Amazon....pero debería!!!!!!

Motion:
This is a FOAM mattress, so no springs or coils. You don’t bounce well if you jump on this bed, but that means when you get up at midnight to pee or if you’re on overnight call for work, your partner won’t feel you getting in and out of bed so you don’t wake them.
Also, the mattress covering isn’t too slippery, so the corners of my bedsheets never spring loose and fly off. It’s nice to wake up and not be tangled in a bottom fitted sheet that escaped in the night!
Noise:
Silent! Foam mattress means there’s no metal crunching or creaking!
Comfort:
It’s not like sinking into a basket of feathers, there’s a bit of firmness to it when you first lie down that softens up and shapes to your body within a minute or two. It’s not so firm that it’s uncomfortable though, and you can always purchase fluffy mattress pads for $100-$300 if you prefer something softer. I find it firm enough to give good lumbar spine support while soft enough to prevent pressure points, so you don’t feel stiff or achy in the mornings. It’s a great sleep!
Height:
I was worried about this bed being too low to the ground because it doesn’t need a box spring, but it is actually taller than my old bed. Mattress and frame together are 24 inches high.
Assembly:
Easy peasy. Had it together in 15 minutes or so. Not like IKEA furniture! Promise!
Price:
Can’t be beat!
Mattress was the 10 inch thick King for $370.
The king sized “Zinus Essential Upholstered Platform Bed Frame” was $235.
Boxspring not needed and delivery free, so for a grand total of $605 we had a king size bed delivered right to our front door!
Compare this to the store prices for a king mattress near us - $1500!! Not including the frame, boxspring, or delivery! I figured if I buy a bed online and it’s not comfy, I could always buy a $300 mattress pad to make it more soft or firm to my liking, and I’d still be saving money than if I bought in a store. But turns out, a mattress pad wasn’t needed at all!
Temperature Control:
Foam mattresses do tend to get warmer than interspring mattresses; I don’t personally find a heat/temperature/moisture difference between this mattress and our old coil one, but YMMV.
Durability:
It’s only been one month so too soon to tell, but so far so good. No sagging, still provides great support,
Overall:
Yes, it was nerve wracking to buy a bed online. But this one was so totally worth it. I’m now recommending this mattress to my friends and family and will definitely purchase again for our spare bedroom!
Hope this info helps you make your mattress shopping a little easier :)

I'm heavy and theres no issue.
Mattress is soft enough on surface but firm enough within to support.
I wake up in the same position I fell asleep in.
That's never happened before !!
I'm sleeping better my joints feel better !
Absolutely expanded to 10" in about 5 hours.
Nice covering.
No bad smell at all for me.
I noticed a smell of new plastic when I opened the clear bag but once I left the room with the plastic bag, it disdipated.
Absolutely no smell once I made the bed
I have a high quality gel topper that I put on top.
I could have done without it but I have it so I used it.
Price was incredible !!!
THANK YOU ZINUS !!!
