Mainstays memory foam mattress topper.

In use for about 3 weeks too soon to tell if this will provide the comfortable support needed 3 or 4 years from now. So far it's great. Shipping was quick and the price was reasonable. Took only 1 hour to return to full shape after unpacking. Just hand stretch it a little and it's fine. No holes or bubbles. Nice uniform light blue color. Perfect!

PLEASE READ FOR A TIP

I LOVE this! I've slept on this for two nights, and no more back or hip pain. The negative reviews mostly state that it was squished and didn't fit the bed, and mine was like that too until I began shaking it out. I laid it on the bed, grabbed the side, and started shaking it, like I would do if I was making waves with the sheet (for the kids, cats, etc.), and it only took a couple of minutes for it to completely fluff out. I don't know if it would've fully fluffed on it's own--it's not like those mattresses in a box, it's a compacted piece of foam that may have been stored that way for months. I bought the 3" and it is VERY thick and plush. I would definitely buy this again.

Like Heaven

This 3” Mainstays memory foam topper made a big difference for my bed. It’s super comfy and adds just the right amount of softness without feeling too squishy. It was easy to set up and expanded quickly. I sleep more comfortably now and wake up with less soreness. For the price, it’s definitely worth it and feels like a great upgrade to an older mattress.
