Review: One of my best purchases of 2025 - Update: I slept on this mattress every single night for six months while my dog battled epilepsy. It allowed both of us to sleep on the floor safely without having to worry about her having a seizures and getting seriously injured by falling off the bed and it allowed me comfort while I slept on the floor next to her. This mattress gave me six months of snuggles and cuddles with a life cut too short. My dog passed away two weeks ago and I folded it up and put it away today. Crying while I did it. It’s just a foldable mattress but it gave me such a sense of peace, comfort, love, and safety every night for the past six months. Never thought I’d be emotional over a mattress but here I am sobbing my eyes out over having to sleep in my actual bed again. Best money I’ve spent. I bought it to sleep on when I had company in town but ended up sleeping on it when my dog got sick. She started having seizures and breathing issues. I slept on the floor by her crate until she was in better health and was so so glad to have a comfortable place to sleep. I don’t know what I would have done with out it. It head a little more support when it was new but it still provides a soft place to lay down. It expanded quickly and off gassed over a couple days. It’s about four inches thick. And it’s just enough that’s it’s easy and light to fold up and move out of the way during the day
Review: Awesome, awesome, awesome! - I ordered two of these to try them out. they worked out so well that I have a third and fourth on order. I have also purchased the 6 inch queen size as well. I rent out an apartment in my home on Airbnb. These are great for allowing guests to have a comfortable sleeping space, while allowing me to be versatile when setting up the apartment. For example: I purchased 4 twin sized mattresses and use them with a fold away metal frame. I can cater the set up to how ever many guests book with me. If it's just a single couple visiting from Philly, I use the queen bed set up, but if it's four college kids from China, I put out the four twin mattresses with fold away frames. When I am not renting out, I stack and fold the beds away in storage and use the space for entertaining. The mattresses are all super comfy, and allow for my guests to get a really great nights sleep. My reviews on Airbnb all reflect a comfortable sleeping arrangement, and I have these mattresses to thank for it. I purchased waterproof mattress covers that are washable to protect the mattresses from spills, and dirt. Even though these are used for short stays in my Bnb, they could easily and enjoyably be used for long term use as well. I think the price is fair for the quality you receive. Set up: Initial set up was very easy. simply remove the rolled up mattress from the box, cut (carefully) the mattress out of the plastic and allow it to lay flat for at least a day or so. I have read other reviews where the mattresses didn't completely plump up or half filled after opening. I'm not sure if they didn't allow them to lay flat or if they just received a dud mattress. All 5 of the mattresses I have purchased (4 twins and 1 queen) opened up with no issues, and all the segments are evenly plump and comfortable. There is a slight chemical smell when you initially open them, but I let them air out for a couple of days then sprayed a little febreeze on them and the smell was gone. Again, I highly recommend purchasing these mattresses. One note I will pass on, I found that the twin XL sized sheets fit a little better on this mattress. A regular twin will fit, but it will be snug. A normal twin mattress usually has 'rounded' corners where as these have fully squared off corners and i *think* this is where the snugness comes in to play. desertcart Basics offers a great twin XL sheet set (also a purchase of mine) that fits these mattresses perfectly. All in all, these mattresses are a great investment for someone looking to have easy to store away beds for guests or family visiting. Highly recommended!

Let me tell you about this sleeping mattress . I've tried quite a few mattresses in my time – some that felt like they were made from the backside of a Hutt, and others that left me more restless than a dianoga in a bathtub. But this one? It's a real game-changer! When I first plopped my... er, considerable presence onto this mattress, I was skeptical. After all, comfort isn't exactly a trait associated with my lifestyle. But lo and behold, it was like sinking into a pool of carbonite – supportive yet oh-so-gentle. I've slept like a rancor that's been fed a barrel of nerf steak every night since I got this mattress. The way it cradles my... unique physique is something to behold. It's like a warm Hoth summer's day wrapped in a cozy Tauntaun hide. I've hosted quite a few soirees in my palace, and let me tell you, even my fellow Hutt cronies were amazed by the comfort this mattress provided. No one believed that a mattress could make me, of all beings, look forward to bedtime. I even caught Bib Fortuna trying to sneak a nap on it – quite the sight, I must say! As I recline on this glorious marvel of sleep technology, I can't help but marvel at how it's transformed my slumber. No more tossing and turning like a starfighter caught in a tractor beam; just pure, uninterrupted beauty sleep that leaves me feeling rejuvenated and ready to tackle the challenges of being a galaxy-renowned crime lord. So, if you're searching for a mattress that'll cradle you in comfort like a Gamorrean cradles his vibro-axe, look no further. This is the mattress you've been looking for – a true sleep oasis in a desert of subpar slumber solutions. May the Zzz's be with you, my friends!
