bed in a box

It is best to listen to all the instructions. Given to you, they even give you a cutting tool. If you do it gradually, it will inflate slowly. There's no telling how long it's been deflated, so it will take some time to inflate once again. The majority of it will expand quickly, but there will be some parts of it that will take time to get acclimated to its use. Space. I put it on top of the bed. I cut it open very slightly. It inflated slowly, then I hesitated to remove the old mattress, and I just inflated the new one on top of the old giving it to the high-rise. Look, being that the old one was already 8. It's just wide and this oneone0 is one8 on top of the box spring. It has soft sides in the beginning, but after sleeping throughout the night, it has stiffened up quite a bit, and I bet that throughout the next days or so, it will stiffen a bit more.

Super happy with my purchase!

I have to say I'm always scared ordering a bed online but, in this case, I'm SUPPER HAPPY! Just as pictured. I have slept so good every night. I usually toss and turn throughout the night because I have back issues. I would highly recommend this bed. It has a nice give to it. It's not firm like my other one. I would hurt every morning when getting up but haven't since sleeping on this bed. Even hubby said after the first night sleeping on in how much better he slept. I'm so glad I decided on this bed. If you like a NOT to firm bed that lets you sink in where needed. then you will like this bed. Again, I'm super happy with this bed and super happy with how fast I got it.
