r/Mattress on Reddit: Recommendations for 5" twin mattress, please!
August 22, 2024 -

I'm looking for recommendations for 5" mattress (preferably foam) that will be mostly comfortable for adults (weights from 150 - 200 lb) who prefer medium firm to firm mattress. We recently bought the Utaker Stackable Twin from Ikea for our guest room with the idea that they will eventually transition to kid beds for our 4 year old and new baby due in September. I'd like to get a couple of decent mattresses for family who will be coming to help out with the new baby next month.

Any recommendations?

UPDATE

We bought the Bear Trundle Mattress. They're a little bit tight, but totally safe and usable. My 180 lb 73 year old father slept on it and said it was very comfortable. Both my spouse and I have taken naps on them and found them to be comfortable. They were firm, but comfortable for stomach/back sleepers.

We actually did the same thing with the Utaker setup; super handy for kid rooms and guests! For a memory foam twin mattress, we went with the Lucid 5" firm gel option, and it surprised us. It’s firm enough for adults (my dad is 190lbs and said it felt totally fine), but still comfy for littles down the line. Plus, the gel foam helped keep it a bit cooler, which our guest room desperately needed. Price-wise, it didn’t break the bank either. Congrats on the new baby, btw—exciting times! 👶

5 inches is tough for adults. I had a very similar setup for guests last year with stackable frames. What we did then was two Walmart Mainstays twins (6 inches), then added two two inch memory foam pads on top. Was surprisingly fine for occasional sleeping, but not amazing and won't hold up honestly. Its a cheap spring thing that feels like a nursury bed ish but with a foam topper it covers over this fact. We put mattress riser feet under these short frames to make it feel like a more normal bed. That said, a better option for adults could be to do 10 inch mattresses and just stack them high when not in use (and don't have people sit on them when stacked high). Buy them cheap enough that you could swap out if you need to get a thinner one when your kids move into the beds. Costco has a 2 pack Comfort Tech 10 inch foam mattress for $460 online. Brooklyn Bedding 10 inch Standard on Walmart is approx $200 each. I have a queen of this and is better than the list price, although unfortunate that the twin and queen are the same price. 6 inches of foambymail hd36-r or similar is $77 each. I haven't tried this myself, and is low key a little DIY.

5-6 inch mattress okay for small adult?
If your current mattress is good and comfortable they make safety rails you can slide in to add…safety to the setup you have. We use them on my kids bed as we got him a 10” mattress so it was above where the guidelines recommended. More on reddit.com

Tuft and needle discontinued the 5 inch version. Any alternative for that price range?

Nothing of any sort of quality. Those are guest room mattresses, kids mattresses, and mattresses designed for temporary use.

Simple question. Is a 5 inch gap at between mattress and headboard normal?

5.0 inches = 12.7 centimetres 1 inch = 2.54cm

I'm a bot. Downvote to remove.

The Best Mattresses Now?
So as someone who’s done mattress research multiple times, who the heck knows. Memory foam is supposed to last like 10 years so I’d never recommend buying one above $800. Most of those brands you named are just good at marketing themselves to be luxury but tempur-pedicure, Casper, Tuft, etc. are all pretty much the same mattress it just depends on the thickness of each layer and the softness of the higher up ones. It a crapshoot tbh and everyone’s back is different. For brands like sealy and serta, they change their models every year too. I just recommend going to Costco, Sam’s club, or BJ’s and picking up your desired firmness of a mattress. Novaform from Costco is good and my fiancé and I like the soft one of that. Casper was sold at Sam’s and still might be for a decent discount too. More on reddit.com

r/Mattress on Reddit: 5-6 inch mattress okay for small adult?
September 23, 2024 -

Hi, so for context I sleep on a bunk bed. The manual for the frame suggests a bed no greater than 6". The mattress I currently use is 8inches, which means the guard rails are very short and somewhat of a safety risk. I'm thinking of grabbing a cheap mattress, around 5-6 inches, but all of the mattresses and reviews for those mattresses have been for kids.

I'm 4'11", 120-130lbs, and have lower back problems due to a spinal birth defect. I need hard beds as I need lots of support for my hip/lower back area, and because I like my spine to feel straight/supported I sleep primarily on my stomach.

I'm just worried if 5 or 6 inches is too thin and if I'll end up feeling the slats of my bunk bed frame, especially if the mattress is something like memory foam (which I've previously slept great on)

I'm on a cheaper budget, and I'm thinking of going for 5 inches maybe because there's a firm 2inch topper I've been eyeing and in case the mattress isn't supportive enough I can add that (it'd be 7 inches total but only 1inch over the max instead of my current 2)
