Mattress Helper Under Mattress Support - Fix Sagging Mattress with Firmer Solution, Single Side Coverage for Half Full/Queen Beds, Yellow

I rarely write reviews, but I'm genuinely thrilled with this mattress support purchase. After minimal research, I decided to try it, thinking even temporary relief would be worthwhile. My partner and I received a bed from my mom's guest room, which was never very comfortable and began sagging on the sides we sleep on, leaving an unsupported middle section. As side and stomach sleepers, this caused significant discomfort in my back, hips, and knees. The product arrived quickly, and though installing it alone was challenging due to the mattress weight and the support's flexibility, I managed. Immediately, I noticed my partner's side still sagged while mine leveled with the middle. Testing it confirmed it worked perfectly on the first try, and after a night's sleep, the improvement was undeniable. I'm overjoyed with the results. For authenticity, check my other reviews—I always provide honest feedback.

After several months of testing, I can confirm this product works exceptionally well. My situation involved a furnished apartment with a worn-out mattress that had developed a noticeable valley in the middle, exacerbating my sciatic nerve issues. When my landlord refused to replace it, I explored futons but found them too expensive. This Mattress Helper, purchased for $59, proved to be the perfect solution. By placing it with a plywood board on the box springs, it completely eliminated the indentation, restoring comfort and support. Initially, it raised the middle slightly higher than the sides, but after a couple of months, the bed leveled out. For shared use, consider purchasing multiple units to ensure even support and prevent valleys between them. Highly recommended for anyone seeking an affordable fix for mattress sagging.

I own a three-year-old high-end latex foam king mattress that began to sag, and I was reluctant to spend thousands on a replacement or contribute to landfill waste. Initially, I tried a single Mattress Helper on the sagging side, but this created an uncomfortable raised lump. Adding a second helper improved things slightly, but because the helpers weren't as long as my bed, dips remained at the head and feet—likely due to the heavy, flexible nature of foam mattresses requiring full-length support. After contacting the company, the owner/inventor offered to send me new Mattress Helper Minis, which have fewer slats. Although the minis I received (with two extra slats) weren't a perfect fit for a king bed (ideally needing three slats), they sufficiently evened out the mattress for comfort by covering almost the entire length. I also had to place heavy cardboard under the helpers to prevent them from slipping through the slats of my foundation, ensuring a solid surface for proper support. After several months, the helpers haven't shifted or flattened. While this solution may not work for everyone given varied mattress types and issues, it's worth trying for most. The owner provided outstanding customer service, including a 30-day trial, personalized assistance, and follow-ups. I value supporting companies that prioritize customer care. Note: The minis aren't currently on Amazon but can be purchased directly from the company. They also worked well for my sagging sofa. Update (5/29/16): About six months ago, I needed a new mattress as the poly foam in the helpers eventually broke down, similar to mattress foam, providing only about a year of relief. My parents experienced the same issue. Due to this short lifespan and a price increase, I've downgraded my rating to four stars. It may still be a viable short-term fix, and the service remains excellent, but don't expect a long-term solution. For a new mattress, consider online options, which are often more affordable, higher quality, and better supported than retail stores.
