My family bought me a similar Serta topper 5 yrs ago after a major surgery. My matress has seen better days. The first one was very comfortable and I was still using it but my large dog digs at the bed before laying down and did rip it. Honestly, the first one was a little too soft. I had a full open abdominal so those muscles were cut and I have bad joints , so sitting up can be tricky. I found you sink in and had to actually roll to get up. This Serta topper is much more comfortable & much easier to get up from because all though soft, it is firmer. It bounces right back after you get up. . It gives but doesn't make you sink. This helps sleeping when you have joint pain. I didnt feel as hot with it as much as the first either but could just be me. It came in a solid box ,( grandkids LOVE the box with the sheep and large flaps lol) compressed, well wrapped and in a duffle bag. It was fully expanded as soon as I opened it. I didnt notice any smells. This was the best sleep I've had in a long time and at this price I've considered buying an extra when it inevitably rips and wears down but I've read some reviews online that toppers didn't fully expanded after stored a long time. Ill just enjoy this till it dies and replace it then. It was very fast shipping also. I HIGHLY RECOMMEND THIS & WILL buy again! Review: Great quality mattress - Great memory foam mattress for the price. This is a great alternative to replacing my whole mattress. Great quality mattress, so comfortable and soft. The mattress doesn’t move around when I sleep which is awesome. My back pain is gone. Definitely recommend this mattress. ## Features - UPGRADES FULL-SIZE DORM & APARTMENT BEDS: Sized 53" x 75" to fit standard Full mattresses common in suite-style dorms and off-campus apartments.

This is a great alternative to replacing my whole mattress. Great quality mattress, so comfortable and soft. The mattress doesn’t move around when I sleep which is awesome. My back pain is gone. Definitely recommend this mattress. ### ⭐⭐⭐⭐ My back pain improved, pros & cons *by M***. on September 25, 2025* I haven't been a fan of memory foam in the past, but I went on vacation and slept on a memory foam bed. I noticed my back was not hurting as much, I've had chronic back pain for years. So when I got home I added this topper to my bed. The first night or two took some getting used to, but my back was feeling better so I stuck with it. Its been and week now and I must say, I don't think I could sleep well without it now...once you get used to it, its really comfy and I don't wake up with back pain anymore and better through the day.. *The downside is that it is not "cooling" and I'm a hot sleeper. We just had a heatwave, so I think it'll be better as the weather gets colder. I would definitely recommend this to those with back pain, it made a big difference for me. Update: still sleeping better, however on the nights that my back is really bothering me, it's challenging to turn over, since you sink a bit into the memory foam. I am still sleeping more solidly, dreaming a lot, which means I am getting more REM sleep than in the past. ## Frequently Bought Together - Serta ThermaGel Cooling, Pressure-Relieving Memory Foam Mattress Topper, 3 Inch, Full,Blue - EASELAND (Full, White) - Luxury Hotel Quilted Mattress Pad Cover 300TC 100% Cotton Top - Goose Down Alternative Filling -Stretch Up to 8-50cm Deep -Mattress Topper (Full, White) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/208669180-serta-thermagel-cooling-pressure-relieving-memory-foam-mattress-topper-3](https://www.desertcart.co.za/products/208669180-serta-thermagel-cooling-pressure-relieving-memory-foam-mattress-topper-3) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-21*
