I am experiencing this right now. My daughter bought me a new mattress, and set it up last night. It turns out the mattress which is listed as "firm hybrid, memory foam and coils", is really just a big memory foam pad. It's so squishy that one topples, a little, when they sit up. There are no springs at all, except individual ones at the corners. It's a big wobbly pillow. No springiness or support at all.
My old mattress I had all through cancer, and recovery. It is in poor condition as I have spent about half of my days in bed for several years, and when I had cancer, I was in bed all day.
The description, I looked at it online, it's so deceptive. It's not a mattress at all. It is just a big foam pad. When you go from sitting to standing, that force is enough for me to feel the box spring underneath, for a moment.
I would honestly say that my old mattress was way better. A nice, firm, supportive bed. But the problem is that springs are starting to poke out. It's truly an awful bed. But way more supportive than the new one.
I am writing this at 4:30 a.m. I haven't even slept one whole night in it, and I'm miserable.
My daughter was so happy to get me the bed. My big surprise. Only 80 dollars. But it's all she could afford. I'm dreading telling her that we're going to have to return it. She was beaming with joy. And I was so excited to sleep in the new bed as well, to be honest. She's had so many disappointments lately, I don't want to add to it. I have been tempted for hours to go out and sleep on my recliner, or my old mattress, that we haven't disposed of yet, on the floor.
She's had so few reasons to smile lately. This is going to suck.
