Yeah its a bummer
@Sasha .
I am also still shielding apart from my carers, who all wear N95 masks & overalls.
But...Just in case its helpful.... I have been
forced to have workmen/delivery men into my house, including upstairs, a total of THIRTEEN times this year, including to deliver a new bed, new washing machine upstairs toilet broke had to be replaced, then downstairs one, a flood, a boiler issue etc etc, it's been a catalogue of disaster! So i've got safe 'intruders' down to a fine art... Here is what i do - just in case it's helpful. (the following is a list of what some would say are paranoia levels of hygeine measures, but i still safe after all those 'intruders' s i'm sticking to it... so if you not interested in reading that just skip to the nxt post)
I provide an N95 mask for them which i leave in a box on the doorstep, & explain (if possible on the phone beforehand, but if not then out of the window before i answer the door, starting with "I'm so sorry I know its a pain but I'm still shielding & still extremely vulnerable to covid, & have been advised that a cloth mask is insufficient to protect me, would you mind awfully wearing the one i provide etc) they are always happy to do so. I then open
every window in the property - wide getting a through breeze.
Then when i open the door, again i apologise, & ask nicely for them to walk/step through the large tray that i put in the doorway with lemon zoflora disinfectant in it (so they're not paddling germs up the stairs from wherever they've been prior) - lemon because it doesnt smell as strong & it's clear - doesnt mark the carpet. It's in a low sided tray with a large spongey cloth in, so it doesnt slip slide in the tray - you can step into & out of it easily.
They go wherever they need to go/do what they need to do but i keep a close eye on what they touch - with their bodies as well as their hands. I wear an N99/FFP3 mask while they are here & also for about 30mins after they leave depending on how windy it is & whether i think the air has been replaced yet.
Then i go round & spray or wipe with either DEW, or zoflora, everything they touched, including banisters etc.
Delivery men dont touch much, but their arses do rub on door frames & hands on banisters on way back downstairs
(lol i say 'I' go round & wipe up... i have to have carers there when they come, especially for workmen as they tend to touch a lot more, & all the wiping would be way too much for me). Where possible furniture gets covered in blankets (which are folded up very slowly & carefully to avoid dislodging particles after they go, & left to decontaminate for a few days - you have to assess before hand whether it wouls be easier to cover the item or wipe it.
When i had the bed delivered I slept on the settee for 2 nights while it 'decontaminated', which was very unpleasant, but better than risk of covid, or anxiety about it.
I think that is all much less risky than going to a store to lay on one to try it, where the environment is less controlled by you & a dozen other people have laid on it that day. ugh
so if you ordered a topper from one of the firms that do a 30 night trial for a full refund if you dont like it, then it might be possible to try one at home & get it delivered/collected direct from your bedroom if you dont like it.
