Linenspa 3 Inch Gel Memory Foam Mattress Topper - Twin XL Size, Blue Swirl Design | Pressure Relief & Airflow Technology for Better Sleep | Perfect for Guest Beds, Dorm Rooms & Home Comfort Upgrade

We have loved our king sleep number bed because of the side by side air adjustable firmness. My wife setting is 70, I am 50. We had the older C model, no topper, so we always added a 3" memory foam topper and a plush, pillowy, water proof, mattress pad. The combo of dialing in the firmness with the air, and plushness of the topper & pad gave us the best sleep. It is awesome.Now, we get a new bed, cuz we wanted the base to tilt up the head (and feet) which helps for snoring. We need a spit king (3 twin-xls) for the this. Loved the tilting, snoring is better, but hated the foam toppers that came with the i8. It's foam did not really spring back and had only 1/4 inch bumps. We removed them and replaced them with two twin-XL of these 3" memory foam toppers. They resembled the king version we had before. The bumps add cooling as previously. We loved them. As good, if not better than our old ones.Out of the box, they smelled just a bit, and it dissipated before we slept on them the first night.They unrolled and puffed up in less than 20 min.They fit well on the twin-XL mattress and the pad held them in place individually very well.You can see that they are really 3.4 in high (in picture) to the peaks and 2 in in the valleys.They also spring back nicely as our old ones did when you press your hand on.We bought these tentatively because of all the reviews and varying pictures. But they look like they should, blue, thick and bumpy, and work like they should too. I think the bad reviews and pictures are all old ones or from a bad batch or something. We Love em. A bit pricey for the pair of twin-xls to make a king. Thought about buying the cheaper solo king version and then just cutting them in half but didn't. They should sell tow xl-twins as a pair and give a discount.PS: The WhatsBedding Waterproof Mattress Pad Twin XL pair nicely with these memory foam toppers. Nice and puffly and plush pads.
